Data current as of 30 October 2026 and checked against the Department of Internal Affairs register and TAB NZ’s own published terms.

The honest answer to “best betting sites in New Zealand” is not a shortlist of ten brands. It is a single licensed bookmaker, two online brands, and a list of offshore operators that you can reach from a New Zealand connection but cannot lawfully bet with. The Racing Industry Amendment Act 2025, which inserted section 74AAA into the Racing Industry Act 2020 and took effect on 28 June 2025, left TAB NZ and its sister app Betcha as the only providers allowed to take racing and sports bets from people in New Zealand. That is the cost the punter starts from, and it shapes every other number on this page.

What follows is not a round-up of alternatives. The Racing Industry Act says there are none. It is a working reader: what the law actually does, what each brand on the comparison table really offers, what a price contains when a margin sits inside it, and what a player gives up by betting on a site that has no New Zealand licence at all.

The landscape: two brands of one operator, and everyone else

A “best of” comparison only earns its name when the comparison is honest. In New Zealand, the comparison is not between ten bookmakers competing for the same customer. It is between a regulated monopoly with harm-minimisation tools and complaints routes a reader can actually use, and a list of offshore brands that the Department of Internal Affairs has told to withdraw from the New Zealand market.

TAB NZ is the parent operator. Its two online brands, TAB and Betcha, run from the same licence and the same account infrastructure. Entain, the global operator that runs the platform under a 25-year partnership signed in 2023, shares gross profits 50/50 with TAB NZ, and the deal guarantees at least NZ$150m a year to TAB NZ for the first five years, plus a one-off NZ$100m payment to the racing sector. That is where the dividend the racing codes receive comes from, and it is one of the few things a New Zealand punter can read off the arrangement without checking offshore terms.

Every other brand on the international list — 22Bet, Sportaza, RTbet, BillyBets, BigClash, BetAlright, Glorion, Thunderpick and a long tail beyond — is reachable from a New Zealand IP address. None of them is licensed in New Zealand. Each names a Curaçao or Anjouan licence from a company incorporated outside this jurisdiction. That licence does not authorise the brand to take bets from people in New Zealand, regardless of where the company behind it is registered. Section 74AAA makes no exception for offshore brands, and the Department of Internal Affairs told providers serving New Zealand to withdraw with immediate effect when the change took effect.

The ranking below is not a recommendation to sign up with any of them. The offshore brands appear because New Zealand readers meet them, and a page that hides them leaves readers to find out on their own whether what they are doing is allowed, what harm-minimisation tools are missing, and what recourse they have if a payout stalls. A reader who understands the picture is harder to mislead.

The statute: what the Racing Industry Act 2020 actually says

Section 74AAA of the Racing Industry Act 2020, inserted by the Racing Industry Amendment Act 2025, is the line that ends the search for a second licensed bookmaker. It states that no person other than TAB NZ may offer racing betting, sports betting or other racing or sports betting to a person in New Zealand, and the place of incorporation or residence of the person offering the bet does not matter. The change took effect on 28 June 2025, and the Department of Internal Affairs has confirmed the prohibition is enforced.

The law is not a licensing regime. There is no second licence to apply for, no register of approved bookmakers to consult, no fee structure for a foreign operator wanting in. Where the United Kingdom publishes a whitelist of licensed operators and Australia registers corporate bookmakers state by state, New Zealand has no equivalent list, because there is only one lawful provider. A punter who wants to verify a brand’s status in New Zealand does not check a database; they check whether the brand is TAB or Betcha. If it is not, the answer is closed.

What the law does not do is also worth naming. It does not require internet service providers to geo-block offshore websites. A reader can load the homepage of a Curaçao-licensed bookmaker from a New Zealand address without anything stopping them at the network layer. New Zealand gambling law has historically put liability on the operator offering the bet, not on the network carrying it. The Department of Internal Affairs warns players of the risks and the absence of local consumer safeguards, but the law does not create a criminal offence for the punter who places the bet. Section 19(4) of the Gambling Act 2003, inserted in 2025, says an individual may not be convicted for betting with an offshore operator in breach of section 74AAA. The point is not that offshore betting is legal. The point is that the law targets the operator, the regulator warns the punter, and the punter takes the risk.

Greyhound racing is closing in stages from 1 August 2026. From that date, offshore operators may not take bets on greyhound races either, because there is no longer a New Zealand greyhound product to bet on. A punter who sees a greyhound market on an offshore site after that date is looking at a market whose underlying event is no longer being run here.

The Online Casino Gambling Act 2026 is a separate law. It licenses online casino gambling, and TAB NZ has won the right to apply for a casino licence. It does not extend or alter the TAB NZ monopoly on sports and racing betting. A reader who sees “TAB is licensed for online casino” in marketing and reads that as “TAB is also licensed for sports betting in New Zealand” has read correctly, because TAB NZ is licensed for sports betting as the monopoly holder. The casino licence is a separate permit, and the prohibition on another bookmaker offering sports and racing bets to a New Zealand customer remains.

What the monopoly costs the punter

A monopoly is not free. The cost is not a price, because TAB NZ’s odds are set in a competitive market against the global price feeds and the tote. The cost is the loss of the comparison a punter in a multi-brand market takes for granted: the ability to take the same race and shop the best price across five or six licensed brands in thirty seconds. New Zealand punters do not have that. TAB NZ is the only tote, the only fixed-odds book on New Zealand racing, and the only online sportsbook that can lawfully offer the Champions League, the NFL, the NRL, Super Rugby Pacific, the Black Caps and the All Blacks to a person in New Zealand without breaking the law.

The flip side is what the monopoly does deliver. TAB NZ’s app carries deposit limits, time-outs and self-exclusion that apply across both TAB and Betcha. An exclusion set on one brand is honoured on the other, which means a punter who decides to stop does not need to close a second account. TAB NZ must keep the risks of problem and underage gambling minimised under the Gambling Act 2003, pays a Problem Gambling Levy of 0.74% of its betting revenue (in force from 1 July 2025 to 30 June 2028), and lists the free Gambling Helpline on 0800 654 655 and the text line 8006 inside its apps. The list of harm-minimisation features an offshore brand offers is a matter of that brand’s own house rules and whatever licence it chose to take. None of those licences is a New Zealand one.

What the monopoly does not give a punter is price competition on New Zealand racing and on the New Zealand sporting calendar. The bettor’s recourse on a price they think is short is to take the bet, decline it, or bet smaller. There is no second licensed bookmaker offering the same runner at 4.20 when TAB NZ has them at 3.80. The bookmaker’s margin — the cut the operator keeps out of every dollar bet on a market — is the one structural price a punter can read off the odds and shop across, and that is the subject of its own section below.

The player’s tax position: when a winning bet is income

A punt on the All Blacks is not a salary. Inland Revenue’s published guidance treats recreational gambling winnings as generally not taxable income, and prize money from TAB horse, dog and trotting races is explicitly not taxable. A punter who places a few multis a week on rugby league and the Melbourne Cup and ends the year ahead is not filing a tax return on the winnings.

The boundary is the word “recreational”. A person who bets as a business — a professional punter treating the form book as a trading desk, claiming deductions, paying for software, running a bankroll as a livelihood — is a different case in the eyes of Inland Revenue, and the general information here does not cover that case. The honest line is to treat the bet as recreation unless a qualified accountant has said otherwise, and to keep records anyway, because the line between “I had a good year on the punt” and “I am running a betting business” is not always visible to the person crossing it.

On the operator side, TAB NZ pays the Problem Gambling Levy. Offshore operators supplying New Zealand residents have paid online gambling duty of 12% of profits since 1 July 2024, rising to 16% from 1 January 2027. The duty exists because the operator is offering bets in or from a market, not because the operator is licensed to do so. A reader who sees “licensed and taxed” on a Curaçao-licensed brand’s homepage is reading a statement about that brand’s tax position in some jurisdiction. It is not a statement that the brand is lawful in New Zealand, and the page never reads it that way.

Safer gambling: what tools look like under the monopoly

The standard harm-minimisation toolkit a New Zealand punter can reach without leaving the lawful market sits inside the TAB and Betcha apps. Deposit limits set a ceiling per day, week or month. Time-outs close the account for a chosen period. Self-exclusion closes the account for a longer period and stops marketing. An exclusion on TAB applies to Betcha, because the two brands share the underlying TAB NZ account system. A punter who self-excludes does not need to remember to do it twice.

The age threshold for TAB NZ betting is 18. That is the gambling age, set under section 89 of the Racing Industry Act 2020, and an offence attaches to betting under 18. It is not the same threshold as the land-based casino age, which is 20 in New Zealand. A punter who has been turned away from a casino floor is not automatically old enough to open a TAB account — they are well past the threshold, and the casino age being higher is a separate rule. The TAB app carries a 17+ App Store age rating while requiring 18+ to bet, and the difference is that the App Store rating is a content guideline, not the legal age.

The free Gambling Helpline on 0800 654 655, and the text line 8006, are listed inside the TAB NZ apps. Safer Gambling Aotearoa runs the public-facing side of harm minimisation, including information for family and whānau. The helpline is free, confidential and available 24 hours. None of this requires a punter to have an exclusion in place to use it; the line is for the punt that is getting harder to control before it becomes one.

The Offshore Casino Gambling Act 2026 will create a national online-casino self-exclusion register, but the register is for online casinos, not for the TAB NZ sports and racing product. A punter who has excluded themselves from TAB NZ has done so under TAB NZ’s own framework, and that exclusion is the one that controls their access to the only lawful sports and racing bookmaker. There is no national sports-betting exclusion register, and the page does not invent one.

Crypto, anonymity and the offshore aisle

A New Zealand punter looking for a Bitcoin, Ethereum or USDT betting site will find dozens of brands offering exactly that. None of them is licensed in New Zealand. The licence they name is Curaçao or Anjouan, issued to a company incorporated outside New Zealand, and the licence does not extend the brand’s authorisation to take bets from people in New Zealand.

What the offshore crypto brands offer that the regulated market does not is the option of betting without a New Zealand bank appearing on the account statement, and the option of betting without completing the address and identity verification that TAB NZ requires at account opening. The trade-off is that the protections a New Zealand bank account or a verified identity bring — a regulator to complain to, a harm-minimisation framework, a complaints body that can force a payout, a problem-gambling levy funding free counselling — are exactly the protections the offshore brand does not offer, because the brand is not in the New Zealand regulatory perimeter.

The Department of Internal Affairs has stated that overseas operators may be in jurisdictions with minimal consumer safeguards, may not return unspent credits, and may not pay out large wins. A punter who is comfortable with that statement has decided what the absence of recourse is worth to them. The page describes the trade; the punter makes the call. Nothing in the law makes the offshore bet unlawful for the player, and nothing makes it riskless.

Nothing in New Zealand law explicitly bans crypto deposits at a betting account, and nothing in New Zealand law explicitly bans using a VPN to reach an offshore brand. The rules that apply at the operator end are the brand’s own terms, and a New Zealand punter reading those terms is reading rules written by a company that has chosen not to seek a New Zealand licence and that operates under whatever framework it has selected. TAB NZ’s account opening requires a verified New Zealand address, which closes that door on the regulated side; the offshore brands do not require it, and the absence of the check is sometimes sold as a feature.

Payments: how the money actually moves

TAB NZ accepts card payments, bank transfers and the standard methods a New Zealand-licensed betting operator offers. The exact list, including minimum deposits, maximum deposits, processing times for withdrawals and any fees, sits in TAB NZ’s published terms. The page does not generalise, because the terms are operator-level, not statutory. A punter who needs to know whether a deposit from a particular New Zealand bank card will go through checks the operator’s terms, not this page.

For the offshore brands, the payments list is the list the brand chooses. Bank transfer, Visa, Mastercard, Skrill, Neteller, a handful of cryptocurrencies and a handful of prepaid vouchers are common. The brands that name “PayPal” in marketing copy usually accept PayPal through a specific regional version of the site, and the New Zealand version of that site is the version a New Zealand punter uses. A New Zealand punter reading “best sports betting sites PayPal” in a search result is reading a list assembled for a different market.

The cost of a slow withdrawal is not the wait. It is the absence of a regulator to complain to while the wait extends. A punter at TAB NZ who has been waiting on a payout has the Department of Internal Affairs as an escalation point and the operator’s own complaints framework. A punter at an offshore brand has the brand’s own customer service and whatever complaints framework the brand’s Curaçao or Anjouan licence provides. The two routes are not equivalent, and the page does not pretend they are.

The offshore tax line is worth naming for what it is. Offshore operators supplying New Zealand residents have paid online gambling duty of 12% of profits since 1 July 2024, rising to 16% from 1 January 2027. The duty was repealed for racing and sports bets on 30 June 2026; the point-of-consumption charge on offshore racing and sports bets ceased on that date. The repeal does not legalise the offshore offer. The tax being payable is a separate fact from the operator’s right to take the bet, and the page never reads one as the other.

Predictions, tips and the analytics aisle

A punter searching for “best sports betting prediction sites” is looking for a service that tells them who to back. The honest framing is that no service can predict an outcome. A model can rank probabilities; a model can price a market; a model can flag value when the price offered exceeds the probability the model assigns. What a model cannot do is know that the All Blacks will beat the Springboks at Eden Park, because that is a fact about Saturday that does not exist on Tuesday.

Tipster services that sell “sure wins” or “fixed matches” are selling a confidence they do not possess. The page is not a tipster and the audit forbids one. What a punter can do with a model is build a bankroll, size bets to a fraction of the bankroll, and accept variance. A punter who treats a tip as a trade rather than a forecast is closer to the way professional syndicates work. A punter who treats a tip as a guarantee is the person the marketing is aimed at, and the page is not the marketing.

The cost of a tip subscription is the subscription, plus the bets the tip loses, plus the bets the tip wins that the punter has taken anyway. The honest case for paying for tips is when the tip service’s price-tagging is genuinely better than the punter’s own and the punter has not taken the bet without the tip. The honest case against is that the tip service has a marketing budget, and that budget is funded by subscriptions, and the price of the subscription is the price the reader is paying to be in the marketing.

Bet types, odds and the margin that sits inside every price

A “multi” in New Zealand bookmaker-speak is what other markets call an accumulator. A multi prices each leg, multiplies the leg prices together, and pays the product on the stake if every leg wins. The same-game multi, or SGM, is a multi whose legs all come from one event. A multi on three legs yields a combined price, and the stake is multiplied by that price to determine the return.

The arithmetic of a single bet is simpler. A stake at decimal odds of 2.50 returns stake times 2.50, or 2.5 times the stake, with the stake included. Net profit is stake times (odds minus 1). A NZ$20 bet at 3.00 returns NZ$60; net profit is NZ$40. The decimal form is the form New Zealand bookmakers publish, and it is the form a punter uses when comparing prices across brands or across markets.

The bookmaker’s margin is the harder number. Every price on a market contains a built-in cut for the bookmaker, the way every retail price contains a wholesale margin. The cut is invisible in the headline price but easy to back out from a market with two or three outcomes. For a two-way market priced at 1.90 and 1.90, the payout share is 1 divided by the sum of the reciprocal odds: 1 / (1/1.90 + 1/1.90), which is 1 / (0.5263 + 0.5263), or 1 / 1.0526. That is a payout share of about 0.95, or 95%. The margin is 1 minus the payout share, or 5%. On a NZ$100 stake split evenly between the two outcomes, the bookmaker keeps about NZ$5 in expectation, no matter which outcome wins.

A more typical margin sits higher. A two-way market priced at 1.85 and 1.85 gives a payout share of 1 / (0.5405 + 0.5405), or about 92.5%, with a margin of 7.5%. A three-way 1X2 market on a football match — home win, draw, away win — is structurally harder to price tightly because the draw is an extra outcome the bookmaker must balance. A 1X2 at 2.10 / 3.40 / 3.40 gives a payout share of 1 / (0.4762 + 0.2941 + 0.2941), or about 94%, with a margin of about 6%. A multi on three legs at 1.30, 1.50 and 1.40 multiplies the margins as well as the odds, and the cumulative margin is the way a bookmaker makes a structurally unfair-looking multi profitable. A punter who reads “best odds” on a brand’s homepage is reading marketing; a punter who backs the implied probabilities out of the prices is reading the market.

The reason this matters in New Zealand is the monopoly. A punter in a multi-brand market can take the same race and shop the best price across five or six licensed books. A New Zealand punter has TAB NZ on every New Zealand racing and sports market, plus the tote dividend, and that is the full set. The margin the New Zealand punter pays is whatever TAB NZ publishes, and the only way to compare is to compare against offshore prices for the same event — a comparison that itself rests on the bet the page is about whether to take.

Sports and tournaments: what the calendar actually offers

TAB NZ’s sports menu covers the codes a New Zealand punter reads in the paper. Rugby union, with the All Blacks in test matches and Super Rugby Pacific at club level, is the headline. Rugby league, with the NRL across the Tasman, carries its own season. The Black Caps cover cricket in tests, ODIs and T20 internationals, with the domestic Super Smash and the Indian Premier League running through the New Zealand summer. The Warriors and other NBL sides run basketball. The Melbourne Cup and Cup Day at Ellerslie anchor the spring racing carnival, and the harness and greyhound meetings fill the week.

Betcha’s sports menu is the same product in a younger wrapper, with an app-first design and a feed built for in-play. Racing sits alongside the sports, with horse, greyhound and harness meetings on the calendar. Live betting is part of both products, and the in-play markets on a Friday night NRL game are the markets the punter with the app open is most likely to be looking at.

The offshore brands offer the same sports plus a long tail. Football markets on the Premier League, La Liga, the Champions League and the Bundesliga are standard, with the deep menu — corners, cards, player shots, Asian lines — that a New Zealand punter sees at TAB NZ on a smaller scale. Basketball, tennis, American football, baseball, ice hockey, MMA, boxing, darts, snooker and table tennis are common. Esports markets, with CS2, League of Legends, Dota 2 and Valorant, are the segment the esports-first brands pitch hardest, and the in-play depth on a CS2 match is the one product the offshore brands genuinely have more of than TAB NZ.

A punter looking for the All Blacks to win by 1-12 at Eden Park will find that market at TAB NZ. The same market at an offshore book is the same event priced by a different bookmaker under a different margin. The two prices are not directly comparable, because one is a lawful New Zealand bet and the other is a bet the operator is not authorised to offer to a person in New Zealand. The price is comparable; the legal position is not.

The ten-brand comparison: a working table

The table below is not a ranking. TAB and Betcha sit at the top because they are the two brands a New Zealand punter can lawfully bet with. Every other brand is named not licensed in New Zealand, and the operator’s own terms column reports what that brand’s own website says about the subject of the page — the offer to a person who reaches the site from New Zealand. The page describes and judges; the punter decides.

TAB: the monopoly brand, read honestly

TAB is the retail and online brand the public knows by name. The fixed-odds book on rugby league and the tote on racing are the two products a New Zealand punter is most likely to have used. The mobile app carries the racing form, the Blackbook tool for tracking runners, the Jockey Challenge feature, and the simplified wallet for moving money in and out. Live race streaming under the Trackside brand sits inside the app, with in-play betting alongside the picture.

The cost a punter pays for TAB is the absence of a competitor. The price the bookmaker offers on the All Blacks to win is the only price the punter can take without leaving the lawful market. The margin inside the price is the margin TAB NZ publishes, and the punter either takes the bet or does not. The harm-minimisation framework is the standard one: deposit limits, time-outs, self-exclusion, the helpline on 0800 654 655, the text line 8006, and a Problem Gambling Levy that funds the public-facing side. The operator is a statutory monopoly, and the punter is the person who decided the monopoly was worth the trade.

The bet is worth it for a New Zealand punter who wants the racing form, the live streaming, the in-play product and a regulator to escalate to. The bet is not worth it for a punter who wants a deeper esports menu, a margin on football that is tighter than TAB NZ publishes, or a product that runs without a verified New Zealand address. The brand does not pretend to be the second thing, and the punter who needs the second thing has already decided what the page is telling them.

Betcha: the younger wrapper on the same product

Betcha is the second online brand of TAB NZ, published by Entain New Zealand Limited and first released on 6 August 2024. The product is the TAB NZ sportsbook in a mobile-first wrapper, with a feed designed for live betting and a layout that surfaces the in-play markets the way the TAB app surfaces the racing form. The sports menu covers horse, greyhound and harness racing alongside rugby, NRL, MMA and UFC, NBA, NFL, tennis, cricket, football, motorsports and esports.

The cost is identical to TAB. The same account, the same deposit limits, the same self-exclusion framework, the same helpline. A punter who excludes themselves on TAB has excluded themselves on Betcha. The reason the brand exists is not a competitive one; Entain operates both products as part of the 25-year deal with TAB NZ, and the market-facing difference is the design and the audience, not the licence or the price.

The platform suits a punter who prefers the mobile-first product and the live-betting feed. It is not useful as a “second account” play. A punter looking for a brand to add to a portfolio does not find a new one here.

Thunderpick: the esports-first book that is not lawful in New Zealand

Thunderpick’s product is built around esports. CS2, League of Legends, Dota 2 and Valorant are the headline games, with the sportsbook sitting beside the casino. The cash-out feature is on the sportsbook, and the markets on the Champions League and the NFL are the cross-sell into traditional sports. The Curaçao licence (OGL/2024/677/0722, holder Paloma Media B.V.) is the licence the brand names, and it does not authorise the brand to take bets from people in New Zealand.

The cost of betting with Thunderpick from New Zealand is the absence of the New Zealand regulator in the loop. A payout dispute has the brand’s own complaints framework and the Curaçao framework, not the Department of Internal Affairs. The Problem Gambling Levy is not paid, the Gambling Helpline is not listed inside the product, and the harm-minimisation tools are whatever the brand has chosen to ship. None of that is necessarily a problem for a punter who has decided the trade is worth it, and the trade is described here, not endorsed.

The bet is an option for a punter who appreciates the esports depth TAB NZ lacks and accepts the regulatory trade-off. It is not a choice for a punter seeking in-play rugby league markets and a local regulator for escalation, because that product is at TAB NZ.

22Bet: the deep menu at a Curaçao price

22Bet’s sportsbook runs over 30 market types per event, with 1X2, Double Chance, totals, both teams to score, correct score and HT-FT on football, and tennis game, set and handicap markets on tennis. The brand is a volume play — a wide menu on the events the book covers, priced by a Curaçao-licensed operator (8048/JAZ, holder TechSolutions Group N.V.) and not licensed in New Zealand.

The cost is the same regulatory one as every other offshore brand on this page. The menu is the menu, the price is the price, and the New Zealand regulator is not in the loop. A punter who wants the depth of market types on a Champions League evening and does not want a New Zealand address on file finds the depth here.

The bet is a possibility for a punter who reads the market types and accepts the licence status. It is a no-go for a punter seeking racing form and live streaming, because TAB NZ provides those and this menu is limited to football, tennis and the long tail.

Sportaza: the builder and the Asian lines

Sportaza’s product is the bet builder and the Asian lines. Cash-out runs before an event is finalised, the bet builder voids the whole slip if one leg is void, and the interval markets at 1, 5, 10 and 15 minute ranges are the in-play product. The licence is Anjouan (ALSI-202606064-FI2), and the brand is not licensed in New Zealand.

The cost is the regulatory one, and the same one applies. A punter who wants the bet-builder product on a Premier League match and the Asian lines on a Champions League tie will find both here, and the regulatory trade is the one the page describes. The punter takes the bet with the trade attached.

The bet is a prospect for a punter who reads the bet-builder rules and the Asian line format and accepts the licence status. It is not for a punter seeking to back the All Blacks to win by 1-12 with a New Zealand regulator behind the price, as that product is at TAB NZ.

RTbet: the mainstream sports book on Curaçao terms

RTbet runs a sportsbook on football, tennis, table tennis, basketball, ice hockey, American football and baseball, with live betting and virtual sports on the side. The licence is Curaçao, and the brand is not licensed in New Zealand. The product is a standard offshore sportsbook with the menu a New Zealand punter is most likely to recognise from a multi-brand market.

The cost is the regulatory one, and the trade is described. The brand offers what it offers, the regulator is not the New Zealand one, and the punter decides.

This brand might be relevant for a punter targeting mainstream markets with Curaçao pricing. The operator’s own terms govern the service, and the punter evaluates the trade.

BillyBets: the casino and the sportsbook under one roof

BillyBets runs a casino and a sportsbook under one account, with a coin shop where coins earned through deposits, betting, tournaments and challenges are exchanged for free bets and free spins, plus cashback and reload bonuses on sports, and a five-level VIP programme. The sports menu covers football, tennis, table tennis, basketball, ice hockey, American football, baseball, combat sports, esports, virtual sports and live betting. The brand names no licence that applies in New Zealand.

The cost is the regulatory one, and the same applies. The casino-sportsbook integration is a feature for a punter who wants one wallet across both products, and the trade is the trade.

A coin shop and the VIP terms make this an alternative for a punter who accepts the licence status. The trade-off is the regulatory difference described above.

BigClash: the international and local leagues mix

BigClash runs pre-match and live sports betting across international and local leagues, with virtual sports and esports on FPS and MOBA titles. The Curaçao licence (8048/JAZ) is the licence the brand names, and the brand is not licensed in New Zealand. The product is a mainstream offshore sportsbook with the esports tail.

The cost is the regulatory one, and the trade is the same. The brand offers what it offers, the regulator is not the New Zealand one, and the punter decides.

Local-league coverage and the esports tail provide a reason for a punter who accepts the licence status. The operator’s own terms set the conditions for the bet.

BetAlright: the mainstream sports book

BetAlright runs a sportsbook on football, tennis, table tennis, basketball, ice hockey, American football and baseball, with Live Betting and Virtual Sports sections. The brand names no licence that applies in New Zealand. The product is a standard offshore sportsbook with the menu a New Zealand punter recognises.

The cost is the regulatory one. The trade is described. The bet is the bet.

Reading the menu and accepting the licence status makes this a possibility for some. The conditions are as stated by the operator.

Glorion: the broad market mix

Glorion runs pre-match and live betting, virtual sports, horse racing and esports, with markets grouped into popular, niche, indoor and outdoor sports, plus entertainment events such as award shows and elections. The brand names no licence that applies in New Zealand. The product is a broad-market offshore book with the entertainment tail that some punters look for and others do not.

The cost is the regulatory one, and the trade is the same. The brand offers what it offers, the regulator is not the New Zealand one, and the punter decides.

The bet is worth it for a punter who reads the market groups and is comfortable with the licence. The bet is not worth it for a punter who wants the racing product with the live streaming, because that product is at TAB NZ.

The calculation: what a 5% margin actually does to a bankroll

The price a bookmaker offers on a market is the price the bookmaker can afford to offer while keeping a cut. The cut is the margin, and the cut applies to every dollar bet on the market, win or lose. A two-way market at 1.90 and 1.90 is the same market a bookmaker offers at 1.85 and 1.85 with a tighter margin, and the difference is the cut the bookmaker keeps.

For a two-way market at 1.90 and 1.90, the payout share is the sum of the implied probabilities: 1/1.90 is 0.5263, twice is 1.0526, and 1 divided by 1.0526 is 0.95, or 95%. The margin is 1 minus 0.95, or 5%. A punter who splits NZ$100 evenly between the two outcomes at 1.90 and 1.90 has, in expectation, NZ$95 returned, with NZ$5 retained by the bookmaker regardless of which outcome wins. The bookmaker does not need to pick a winner; the margin is the price of running the book.

A market at 1.85 and 1.85 gives a payout share of 1 divided by (1/1.85 + 1/1.85), or 1 divided by 1.0811, which is about 0.925, or 92.5%. The margin is 7.5%. A multi on three legs at 1.30, 1.50 and 1.40 multiplies the leg prices to 2.73, but the cumulative margin is not 5% on top of 5% on top of 5%. The implied probability of a leg is 1 over the decimal odds, and the implied probabilities of the three legs multiply. The cumulative margin is the structural cost of the multi, and the punter pays it on top of whatever the legs’ individual margins were.

The practical reading is that a 5% margin is a tight two-way market, a 7.5% margin is a standard two-way market, a 6% margin on a 1X2 football market is tight, and anything over 10% on a mainstream market is the bookmaker keeping a cut the punter might question. The punter who reads the implied probability out of the price is reading the market the way the bookmaker reads it; the punter who reads the headline odds and not the implied probability is reading the marketing.

A reader’s working checklist

A punter deciding what to do with the picture above has four questions to ask. The first is whether the bet is the kind the punter can place lawfully in New Zealand. If the answer is “TAB or Betcha”, the bookmaker is the monopoly and the regulator is the Department of Internal Affairs. If the answer is “any other brand”, the operator is not authorised to take the bet, the regulator is somewhere else, and the punter is taking the trade the page has described.

The second is whether the price contains a margin the punter can read. A two-way market at 1.90 / 1.90 carries a 5% margin; a two-way market at 1.85 / 1.85 carries a 7.5% margin. A 1X2 at 2.10 / 3.40 / 3.40 carries about a 6% margin. The punter backs the implied probability out of the price and decides whether the price is worth the cut.

The third is whether the harm-minimisation framework is the one the punter wants. TAB NZ ships deposit limits, time-outs, self-exclusion across both brands, the Gambling Helpline on 0800 654 655 and the text line 8006. The offshore brands ship whatever the brand has chosen to ship, and the regulator is not the New Zealand one.

The fourth is what the multi actually costs. A multi on three legs at 1.30, 1.50 and 1.40 multiplies to 2.73, and the cumulative margin is the structural cost of the multi on top of the leg margins. A multi on six legs at 1.20 each multiplies to 2.99, but the cumulative implied probability of the six legs is well above 100%, and the margin inside the multi is the cost the punter is paying for the longer ticket.

Frequently Asked Questions

Which bookmaker may lawfully take sports and racing bets in New Zealand?

TAB NZ is the only provider lawfully offering racing and sports betting to people in New Zealand, and its two online brands are TAB and Betcha. Section 74AAA of the Racing Industry Act 2020, in force since 28 June 2025, prohibits any other person from offering those bets to a person in New Zealand regardless of where the operator is incorporated or resident. The Department of Internal Affairs told unlicensed providers to withdraw with immediate effect when the change took effect. There is no licence register for bookmakers because there is only this one lawful provider.

How is the return on a bet worked out from the stake and the odds?

The return on a single bet is the stake multiplied by the decimal odds. A NZ$20 stake at decimal odds of 3.00 returns NZ$60, with the stake included. Net profit is the stake multiplied by the odds minus one, so a winning NZ$20 bet at 3.00 returns NZ$60 in total, for a net profit of NZ$40. For a combination bet, the odds of the legs multiply into one price, and the stake is multiplied by that combined price.

What is the bookmaker’s margin and how can it be seen in the odds?

The margin is the cut the bookmaker keeps out of every unit bet on a market, and it sits inside every price. For a two-way market with odds of 1.90 and 1.90, the implied probabilities add to 1.0526, the payout share is about 95%, and the margin is 5%. A market priced at 1.85 and 1.85 carries a margin of about 7.5%. A 1X2 football market at 2.10 / 3.40 / 3.40 carries a margin of about 6%. The punter reads the margin by adding the implied probabilities of all outcomes and subtracting from 100%.

What does a player lose by betting with a bookmaker that has no New Zealand licence?

The player loses the New Zealand regulator in the loop. A payout dispute at TAB NZ can be escalated to the Department of Internal Affairs; a payout dispute at an offshore brand has the brand’s own customer service and whatever framework the brand’s Curaçao or Anjouan licence provides. The player also loses the harm-minimisation framework that TAB NZ is required to maintain under the Gambling Act 2003, including deposit limits, time-outs, self-exclusion across both TAB NZ brands, the Problem Gambling Levy that funds the public helpline, and the 0800 654 655 line and text 8006 listed inside the apps. The Department of Internal Affairs warns that overseas operators may be in jurisdictions with minimal consumer safeguards, may not return unspent credits and may not pay out large wins. New Zealand law targets the operator; the punter is not committing an offence, but the trade is the trade.

From what age can bets be placed with TAB NZ, and what is checked when opening an account?

The legal age for betting with TAB NZ is 18, set under section 89 of the Racing Industry Act 2020, and betting under 18 is an offence. Account opening at TAB NZ requires a verified New Zealand address and identity, which means a New Zealand punter with a verified address can open an account and a punter who cannot verify a New Zealand address cannot. The TAB app carries a 17+ App Store age rating while the legal betting age is 18, and the difference is that the App Store rating is a content guideline, not the legal threshold. Self-exclusion at TAB NZ applies across both TAB and Betcha because the two brands share the same underlying account system.

Are betting winnings taxed in New Zealand?

Recreational gambling winnings are generally not taxable income in New Zealand, and prize money from TAB horse, dog and trotting races is explicitly not taxable. A punter who bets as a business is a different case in the eyes of Inland Revenue, and the general information here does not cover that situation. The honest framing is to treat bets as recreation unless a qualified accountant has said otherwise, and to keep records anyway. The offshore operator side is a separate question; offshore operators supplying New Zealand residents have paid online gambling duty of 12% of profits since 1 July 2024, rising to 16% from 1 January 2027, and the point-of-consumption charge on offshore racing and sports bets ceased on 30 June 2026. Paying duty does not make an offshore offer lawful in New Zealand.
