Current as of 30 October 2026 against the Racing Industry Act 2020 (as amended in 2025) and the Department of Internal Affairs’ public statements on the betting prohibition.

The shortest version of this page is two sentences. In New Zealand, only TAB NZ and its online sister brand Betcha may lawfully take a sports or racing bet from a person in New Zealand — that has been the position since 28 June 2025, when section 74AAA of the Racing Industry Act 2020 took effect. Every offshore brand a New Zealand punter meets on a comparison site is, by definition, not licensed here, no matter what it calls itself, and the cost of that fact is paid by the punter rather than by the brand.

The angle of this page is cost — what each part of the market takes out of the stake, what a bonus really demands, what a payout restriction actually does to a winning bet, and what the monopoly leaves on the table. Read the law section first; everything else reads differently once the legal frame is set.

Shortlist at a glance: which bookmakers a New Zealand punter can actually use

The table that follows is the comparison this page is built around. Every other section feeds into it; the verdict is in the last column. Read it as a costing sheet rather than a leaderboard: one row is a lawful operator with a regulator behind it, and nine rows are foreign brands that cannot lawfully take a bet from a person in New Zealand and that carry no New Zealand complaints route.

The next ten sections explain why that table looks the way it does — what the monopoly costs, what the law does to offshore brands, what the app and the wallet do to a TAB bet, and what the difference is between a price and a margin.

Fundamentals: what a bookmaker is, and what “best” means in a monopoly

A bookmaker is a counterparty that quotes prices on outcomes and pays out on the ones that happen. In practice that means three things to the punter: a set of markets to bet into, a set of odds that already contains the bookmaker’s margin, and a set of rules about what happens when the bet settles. The cost of using a bookmaker is the sum of those three things: how wide the margin is, how generous the rules are when something goes wrong, and how much of the stake gets eaten by the conditions attached to a promotion.

“Best” in a New Zealand search box usually means “which brand pays out the most” or “which brand has the best bonus”. Both questions are answered before the search starts here, because the law decides the menu. Once the menu is fixed, “best” shifts shape: it becomes a question about price, about how the operator’s terms treat a winning punter, and about the harm-minimisation tools a person can actually reach when a session gets out of hand. The rest of this page is a costing of those three things, in that order.

The bookmaker’s margin is the first cost a punter pays, and it is hidden in the odds. A two-way market priced at 1.90 / 1.90 pays back less than the full stake across both outcomes combined; the gap between what the punter risks and what the bookmaker returns on every dollar is the margin, and the wider it is, the more the bookmaker keeps of every bet. The margin is paid on every bet, win or lose; the only way to avoid paying it is not to bet.

Statute: the law that decides the menu

Section 74AAA of the Racing Industry Act 2020, inserted by the Racing Industry Amendment Act 2025, took effect on 28 June 2025. It says no person other than TAB NZ may offer racing betting, sports betting, or other racing or sports betting to a person in New Zealand, regardless of where that person is resident or incorporated. The Department of Internal Affairs (DIA) told providers serving New Zealand to withdraw with immediate effect when the section came into force. The law does not geo-block offshore sites at the network level; it puts the liability on the offshore operator that chooses to serve a New Zealand address. There is no licence route to apply for and no register of bookmakers, because the section does not contemplate a second lawful provider.

TAB and Betcha are the two online brands of TAB NZ, the holder of the monopoly. They are not rivals — they are one operator group with two front doors, and a self-exclusion set on one applies across both. Entain runs the TAB business under a 25-year agreement signed in 2023; the partnership gives Entain a 50/50 share of gross profits, with at least $150m a year going to TAB NZ for the first five years, and Entain pledged a one-off $100m payment to the racing sector when the deal was signed. The Racing Industry Amendment Act 2025 does not change that partnership; it confirms that only the partner may take the bet.

The Online Casino Gambling Act 2026 is a separate statute. It licenses online casino gambling; it does not open sports or racing betting to anyone other than TAB NZ. TAB New Zealand has won the right to apply for a casino licence, but that right is for casino products, not for sports and racing bets. The greyhound code is closing in stages from 1 August 2026, and from that date offshore operators may not take bets on greyhound races either — the prohibition has moved with the sport.

Two consequences follow for the punter. The first is that the price comparison the rest of this page runs is between a monopoly operator and a list of brands that have no lawful right to be in the comparison at all. The second is that the New Zealand complaints framework — DIA, the Gambling Commission, the Advertising Standards Authority, the Gambling Helpline — reaches TAB NZ and Betcha and reaches no one else on the list. A dispute with a Curaçao-licensed brand is taken up under Curaçao law, in Curaçao, through whatever channel the brand’s terms name; that is a real cost in time and in recovery odds, and it sits on top of the price.

Wellbeing: what the harm-minimisation tools actually do

TAB NZ’s app lists deposit limits, time-outs and self-exclusion. A deposit limit caps what can be loaded into the wallet over a chosen window; a time-out takes the account offline for a chosen period; a self-exclusion closes the account and is intended to last. Because TAB and Betcha are the same operator group, an exclusion set on one brand closes the other as well. The minimum age for a TAB NZ bet is 18 — betting under 18 is an offence under section 89 of the Racing Industry Act 2020. Land-based casino gambling in New Zealand is set at 20, and the two ages are not interchangeable.

Help outside the app is the free Gambling Helpline on 0800 654 655, the text line on 8006, and Safer Gambling Aotearoa. These are reachable by anyone in New Zealand, not only TAB NZ customers. The Problem Gambling Levy funds the helpline and the wider harm-minimisation framework; the levy sits at 0.74% and is in force from 1 July 2025 to 30 June 2028. The helpline and the levy are paid for out of the legal betting market; an offshore bet does not contribute to either.

For the punter, the cost of the framework shows up as a tax on the lawful operator and a free service to the person who needs it. The cost of being outside the framework is paid by the punter who needs help from a brand with no New Zealand obligation to provide it. Offshore brands’ own terms list 18+ as a minimum; none of them names a New Zealand harm-minimisation service.

Blockchain, crypto and anonymity: what the law does to that lane

A search for “bitcoin bookmaker” or “crypto bookmaker” turns up brands that publish a wallet address and settle in Bitcoin, Ethereum or USDT. In New Zealand that lane does not open: section 74AAA closes it for sports and racing, and the law does not distinguish between a bet paid in fiat and a bet paid in crypto. The asset used to fund the bet does not change who the operator is, and the prohibition is on the operator, not on the rail.

The offshore brands on the list that take crypto do so because their home licence allows it; Curaçao, Anjouan, Tobique and the Comoros do not prohibit crypto rails on a sportsbook. None of those licences gives a right to take a bet from a person in New Zealand. The crypto rail is also the rail most exposed to the second cost in this lane: a price move in the asset between deposit and withdrawal can flip a winning bet into a smaller payout in dollar terms, and the operator’s terms are written in the asset rather than in New Zealand dollars. The punter who wants a New Zealand-dollar payout at the end of a bet is the punter who is advised to bet with TAB NZ.

A second anonymity point is worth naming. TAB NZ’s account opening requires a verified New Zealand address and ID, by the operator’s own terms. An offshore crypto brand does not. Anonymity is a feature for some punters, and a cost for others — the customer who needs a New Zealand disputes route is the customer anonymity costs the most. The page does not recommend one path or the other; it names what each one gives up.

Incentives, rollover and the cost of a “free” bet

TAB NZ’s app lists “bonus bets” for new customers, plus a Mega Multi bonus of up to $50 in Bonus Cash when a multi of four or more legs falls short by a set number of legs. Bonus Cash at TAB NZ can be split across multiple bets, so the punter is not forced into one wager to use it. The terms and conditions attached to those offers live on the operator’s own page; this page does not restate them, because the operator’s terms are the contract.

The cost of an offer in this market has three parts. The first is the rollover — how much has to be bet before the bonus or its winnings can be withdrawn. The second is the minimum odds each qualifying bet has to be priced at, because an offer that only counts on long shots is an offer that costs more than it looks. The third is the deadline, because an offer that expires inside a week is an offer that pushes the punter into markets they might not otherwise have chosen. None of those three numbers is on the front of the promotion; all three are in the terms.

The offshore brands on the list describe their own welcome offers in their own terms. A “200% up to 1 BTC” headline is a headline in the asset, not in dollars; the rollover, minimum odds and deadline sit behind the headline and the page does not have them for the offshore set. The safe reading is to assume a heavy turnover requirement relative to the headline value, because that is what a 200% headline costs in this market, and to read the terms before staking.

The same logic applies to “boosted odds” and “risk-free” offers. A boosted price is a single bet with a higher payout if it wins; the cost is the punter’s choice of which leg to attach it to, because a boost on a long shot pays more in absolute terms and costs more in probability. A “risk-free” bet is, in nearly every case, refunded as a free bet whose stake is not paid back with a win — the punter’s net position is the free bet’s value at the offer’s market margin, not the stake. The arithmetic of what a free bet is worth is in the section on the cost of a market.

Cashier: deposits, withdrawals and the rails a punter uses

TAB NZ takes deposits and pays withdrawals through its own wallet inside the app; the wallet is simplified, the deposit methods are operator-level, and no statutory payment rule for New Zealand betting accounts was found. That is the lawful rail: in New Zealand dollars, into a New Zealand-licensed wallet, with a New Zealand complaints route behind it. The cost of using it is whatever the operator’s own deposit and withdrawal terms say, and the page does not have those numbers; the safe move is to read the wallet screen before the first deposit.

Offshore brands take a different set of rails. Some name Visa and Mastercard at the cashier; some name bank transfer and Trustly; some settle only in crypto. A punter using an offshore brand from New Zealand pays three costs at the cashier. The first is the rail’s own fee, where it exists. The second is the conversion cost if the wallet is not in New Zealand dollars. The third is the recovery cost if a withdrawal stalls: a brand licensed in Curaçao or Anjouan is outside the New Zealand complaints framework, and a stuck withdrawal is a real cost in time and in probability of getting the money back. 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. That is the regulator’s own caveat, and it is the cost of the offshore rail.

The “fast payout” promise is the offshore lane’s loudest marketing word. A brand that pays inside an hour on a small e-wallet withdrawal may take a week on a bank transfer, and may stall a large win for a manual review that has nothing to do with the rail. TAB NZ’s payout times are operator-level and are not on the page; the punter who cares about payout time is the punter who is advised to look at the operator’s own terms rather than at the brand’s marketing. A fast payout on a brand with no New Zealand licence is a fast payout into a wallet the New Zealand framework does not reach.

Touchscreen: the app and the browser

TAB NZ’s “TAB – Racing & Sports Betting” app is published on the New Zealand App Store under the seller name New Zealand Racing Board, first released on 8 September 2014. The app carries a 17+ App Store age rating while stating that customers must be 18 or over to bet. The app covers horse and harness racing, rugby union and rugby league and other sports, pre-match and live, and includes Trackside live race streaming with in-app betting, racing form, Blackbook and Jockey Challenge tools, and a simplified wallet for deposits and withdrawals. Same Race Multis, Same Game Multis, one-tap Popular Multis, and a Place Extra option that lets punters back runners to finish up to 10th in selected races are all in the app.

The mobile cost is the difference between a market a punter can reach in two taps and a market that takes four. The TAB NZ app closes that gap by design: Same Game Multis, one-tap Popular Multis and in-play betting on the same screen as the form are all the operator’s own answer to the cost of a slow bet slip. A browser-based bet on a smaller brand takes longer, and a longer bet slip is a bet slip that loses information — odds change while the page loads, a market goes suspended while the punter is on the wrong tab, and the bet that looked good three minutes ago looks ordinary now.

The age rating on the App Store listing is a useful tell about who the operator is willing to be seen by. A 17+ rating is the App Store’s way of saying the app is not a children’s product, while the operator’s own terms set the betting age at 18. A punter who cares about the operator’s own stance on age is advised to read the operator’s own terms rather than the App Store label; the two are related, and the operator’s terms are the contract.

Selection: bet types, odds and the cost of a price

A bookmaker’s odds are its price for each outcome, and the price already contains the margin. A two-way market at 1.90 / 1.90 is a market where the bookmaker keeps about 5% of every unit bet, win or lose. The arithmetic is short: a stake of $10 at 1.90 returns $19 on a win, and the two outcomes together return $19 of the $20 staked, so the bookmaker keeps $1 of every $20. The wider the odds on each side, the wider the margin; the tighter the odds, the tighter the margin. A market at 1.95 / 1.95 pays back more of the stake across both outcomes, and the punter’s cost is lower.

This page is built on one vetted calculation, and it is the calculation of a margin. Take an illustrative two-way market at 1.90 / 1.90: the payout share is 1 divided by the sum of the reciprocal odds, which is 1 divided by (1/1.90 + 1/1.90), or about 0.95, and the margin is 1 minus the payout share, or about 5%. State it as a band, because the actual margin on a real market depends on the market: a 1X2 football market with a heavy favourite sits closer to a 7% margin, a handicap on the same match sits closer to 4%, and a Same Game Multi with three legs is closer to 10% once the legs are correlated. The point is not the exact figure; the point is that the figure is sitting inside every price the punter sees, on every market, on every brand.

The other cost in this section is the cost of a bet type. A multi pays more for the same stake than a single, because the legs multiply into one price; the cost is that every leg has to win, and the probability of every leg winning is the product of the individual probabilities. A Same Game Multi is a multi whose legs come from one event; the legs are correlated, and the margin on a correlated multi is wider than the margin on a multi of unrelated events. TAB NZ’s Same Game Multis, Same Race Multis, Popular Multis and Place Extra option are all the operator’s own products, and the cost of each is the cost of the product type, not the cost of the brand.

Live betting is a separate cost line. The odds on a live market move with the event, and the punter’s window to take a price is shorter. A bookmaker that prices live markets tighter carries a thinner margin and a faster-moving line; a bookmaker that prices them wider carries a fatter margin and a slower line. The choice between the two is a choice about which cost the punter prefers to pay.

Fixtures: sports, codes and what a New Zealand punter bets on

New Zealand punters bet on the codes that matter here. Thoroughbred racing, harness (trots) and, until 1 August 2026, greyhound racing are the racing codes, all under the Racing Industry Act 2020 and the integrity oversight of the Racing Integrity Board. Rugby union — All Blacks, Super Rugby Pacific — and rugby league — NRL, and the New Zealand Warriors — are the rugby codes, with All Blacks test matches the heaviest-priced single event of the year. Cricket is the Black Caps in the international calendar and the domestic Super Smash in the summer. Football runs through the English Premier League, the Champions League and the FIFA calendar; the Melbourne Cup is the racing event that pulls a national pool, and Cup Day sits in the first week of November.

TAB NZ’s app is built around those codes. Horse and harness racing sit alongside rugby union and rugby league in the pre-match and live offering, with Trackside live race streaming inside the app. The app’s form tools — Blackbook, Jockey Challenge, racing form — are racing-first, which is the right weighting for a market where the racing code is the busiest single vertical. A punter who bets mostly on football or basketball will find the football and basketball offering there as well, but the racing depth is the operator’s strongest suit.

The offshore brands in the comparison run different sports ladders. A Curaçao-licensed brand built around European football and esports will carry deeper coverage of La Liga and the Champions League than a TAB NZ account; a brand built around North American sports will carry deeper NBA and NFL coverage. The trade is between depth in a code the punter follows and the absence of a New Zealand right to take the bet. A punter who lives on the Champions League and the NBA is a punter who has the deepest menu offshore, and the highest cost for being there.

The greyhound code is worth naming separately. Greyhound racing closes in stages from 1 August 2026, and from that date offshore operators may not take bets on greyhound races. The market that exists for greyhound betting from offshore brands between the date of publication and the closure date is a market that is closing, and a stake taken in it now is a stake against a market that will not exist at settlement for some events.

Shortlist: a costing of the ten brands

This is the comparison the rest of the page has been building toward. Each operator is rated on the same three things: legal status in New Zealand, what the operator’s own terms say on the key’s subject, and the cost of using the brand from a New Zealand address. The verdicts are the page’s own, written from the facts above.

TAB — the lawful monopoly

TAB is the senior online brand of TAB NZ, the only provider lawfully offering racing and sports betting to people in New Zealand since 28 June 2025. The operator’s own terms are the contract; the app lists deposit limits, time-outs and self-exclusion, and an exclusion set on TAB closes the Betcha side of the wallet as well. Same Game Multis, Same Race Multis, Popular Multis, Place Extra and the in-app Trackside streaming are the operator’s own products; the racing form tools are racing-first, which is the right weighting for a New Zealand punter.

The cost of betting with TAB is the cost of a single-operator market. The price on any given market is the price TAB quotes; the punter does not get to shop the same selection across a second lawful brand, because there is no second lawful brand. The benefit is the regulator behind the operator: DIA, the Gambling Commission, the harm-minimisation framework, the New Zealand complaints route, the in-app tools. The New Zealand punter pays for that framework through the Problem Gambling Levy at 0.74% and through whatever margin TAB builds into its prices. The trade is between a single supplier and the full set of New Zealand protections, and the page’s reading is that the protection is the larger part of the price for a punter who cares about what happens when a session goes wrong.

Betcha — the same operator, the second front door

Betcha is the second online brand of TAB NZ and runs on the same wallet and the same responsible-gambling tools as TAB. A punter signed up to one is signed up to the other for harm-minimisation purposes; the operator is one group. Betcha’s product is the same betting rules, the same markets, the same Trackside streaming and the same form tools, with a different front end aimed at a younger, more mobile-first audience. The promotion structure on Betcha is its own; the terms are TAB NZ’s.

The cost of using Betcha over TAB is the cost of the front end rather than the cost of the operator. A punter who finds Betcha’s interface faster is a punter who loses fewer ticks to a slow bet slip, and the saving is real on a fast-moving market. A punter who finds TAB’s interface faster is a punter who is advised to bet on TAB. The two brands are not rivals; the punter who treats them as a comparison to arbitrage is a punter who has misread the menu.

22Bet — Curaçao-licensed, no New Zealand right

22Bet is run by TechSolutions Group N.V., a Curaçao company with registration number 144920, which also runs 20Bet, Bizzo and National Casino. The Curaçao licence number tied to 22Bet is 8048/JAZ. The Curaçao licence gives 22Bet no right to take bets from a person in New Zealand; section 74AAA does not recognise it, and DIA’s instruction to providers serving New Zealand was to withdraw with immediate effect when the section came into force. The brand’s terms are Curaçao terms; a dispute is a Curaçao dispute.

The cost of using 22Bet from a New Zealand address is the cost of being outside the New Zealand framework. The price on a market may be sharper than TAB’s on a given event, because 22Bet’s book is built for a global market rather than for a single country; the saving is paid for in the absence of a New Zealand disputes route, in the absence of a New Zealand harm-minimisation framework, and in the DIA warning that overseas operators may be in jurisdictions with minimal consumer safeguards, may not return unspent credits and may not pay out large wins. The punter who bets small and never has a dispute is a punter who pays the cost and never notices; the punter who wins big is a punter who notices fast.

Telbet — crypto-led, no New Zealand right

Telbet describes itself as a crypto casino and sportsbook, with a welcome offer of 200% up to 1 BTC plus 50 free spins and a 5 USDT free bet on its Russian-language site. The brand names no licence that applies in New Zealand; the asset is the asset, the licence is whatever the home regulator issued, and the New Zealand right to take the bet is what section 74AAA says it is. The crypto rail exposes the punter to a second cost: a price move in Bitcoin between deposit and withdrawal can flip a winning bet into a smaller payout in dollar terms, on top of the operator’s own terms on the bet.

The cost of using Telbet is the cost of a crypto sportsbook built for a global market and licensed nowhere that reaches New Zealand. The welcome offer is in Bitcoin, the rollover is in the operator’s terms, the minimum odds and the deadline are in the operator’s terms, and the page does not have any of them. The punter who reads the terms before staking is the punter who knows what the offer costs; the punter who reads the headline first is the punter who pays the cost twice.

BetAlright — no named licence, no New Zealand right

BetAlright accepts customers over 18 years of age only and has a separate partners site. The brand’s home page names no licence at all. The 18+ term is a marketing term, not a regulator’s term; the regulator behind it is whatever regulator the home licence names, and where no licence is named there is no regulator at all that the punter can reach.

The cost of using BetAlright from a New Zealand address is the cost of a brand with no published regulator behind it and no New Zealand right. A New Zealand punter with a complaint has no New Zealand route; the operator’s own complaints process is the only route, and that route is built under the operator’s own terms. The 18+ term is the page’s only fact; the rest is the operator’s own marketing. A punter who insists on a regulator behind the brand is advised to avoid this row.

Glorion — support channels, no New Zealand right

Glorion support is available by Live Chat or by email, and the site accepts customers over 18 years of age only. The brand names no licence that applies in New Zealand. The support channels are operator-level; the regulator behind them is whatever regulator the home licence names, and the home licence is not one that reaches New Zealand.

The cost of using Glorion is the cost of a brand with reachable support and no reachable regulator. A punter who needs a quick answer to a cashier question finds it on Live Chat; a punter who needs a regulator to enforce a payout does not. The trade is the standard offshore trade: faster front-line service, slower back-end recovery. The 18+ term is the page’s only fact; the rest is the operator’s own marketing.

LegendPlay — Anjouan-licensed, no New Zealand right

LegendPlay accepts customers over 18 years of age only. The brand names an Anjouan Gaming Authority licence, which gives a right to take bets under Anjouan rules and no right to take bets from a person in New Zealand. The Anjouan licence does not carry the harm-minimisation tools the New Zealand framework requires of TAB NZ, and the Anjouan disputes route is not a New Zealand disputes route.

The cost of using LegendPlay is the cost of a brand licensed in Anjouan and serving a global market from there. The 18+ term is the page’s only fact; the licence is the licence the brand names, and the licence is not one that reaches New Zealand. A punter who needs a regulator behind the brand is advised to look elsewhere.

BigClash — Curaçao-licensed, esports included, no New Zealand right

BigClash offers pre-match and live sports betting across international and local leagues, plus virtual sports and esports betting on FPS and MOBA titles. The brand names a Curaçao licence (8048/JAZ), which gives a right to take bets under Curaçao rules and no right to take bets from a person in New Zealand. The esports and virtuals coverage is the brand’s strongest suit; the New Zealand framework does not reach it.

The cost of using BigClash is the cost of an offshore brand with a deeper esports menu than TAB NZ. The punter who bets mostly on FPS and MOBA titles has a real menu here; the punter who bets mostly on New Zealand racing has none. The trade is between depth in a code the punter follows and the absence of a New Zealand right, and the verdict is the same as the rest of the offshore rows: a punter looking for a New Zealand regulator behind the brand has no place on this row.

Sportaza — Anjouan and Tobique, no New Zealand right

Sportaza’s footer states it is licensed and regulated by the Government of the Autonomous Island of Anjouan, Union of Comoros, under licence No. ALSI-202606064-FI2, while its terms (section 1.4) cite licence No. 0000067 issued by Tobique. The brand names two licences; neither reaches New Zealand. The punter with a complaint has two offshore routes and no New Zealand one.

The cost of using Sportaza is the cost of a brand with two offshore licences and no New Zealand right. The two licences are the brand’s own statement of where it is regulated; the regulator behind the punter’s bet is whichever of the two is current, and the disputes route is whichever of the two the operator’s terms point to. The page’s only fact is the licence statement; the rest is the operator’s own marketing.

Winz.io — Anjouan and Tobique, no New Zealand right

Winz.io states in its footer that it holds a licence delivered by Anjouan and Tobique. The holder is Novatrix SRL, the same company that runs RoyalistPlay and Rooster; the Anjouan and Tobique licences do not reach New Zealand, and the punter with a complaint has an offshore route and no New Zealand one.

The cost of using Winz.io is the cost of a brand licensed through the same vehicle as several others on the offshore list, with the same gap to New Zealand. The punter who bets on the markets Winz.io prices well is a punter who saves on price; the punter who needs a New Zealand regulator is a punter who pays for the absence. The page’s only fact is the licence statement; the rest is the operator’s own marketing.

How the maths works: a worked margin and what it tells a punter

The page’s one calculation is the margin on an illustrative two-way market at 1.90 / 1.90. The payout share on a market with two equally-priced outcomes is the reciprocal of the sum of the reciprocal odds: 1 divided by (1/1.90 plus 1/1.90), or about 0.95. The margin is 1 minus the payout share, or about 5%. State it as a band, because real markets sit at different margins: a 1X2 football market with a heavy favourite is closer to 7%, a handicap on the same match is closer to 4%, and a Same Game Multi with three correlated legs is closer to 10%. The point is not the exact figure; the point is that the figure sits inside every price, on every market, on every brand, and the punter pays it on every bet, win or lose.

The cost of a margin in dollar terms is straightforward. A punter who bets $100 across 20 markets at an average margin of 5% has staked $2,000 and paid $100 in expected margin, win or lose, before any selection is settled. The saving between the two is the saving on the price, and it is paid up front rather than at settlement. A punter who wants the saving is a punter who shops the price, and a punter who bets with a single monopoly operator is a punter who does not get to shop.

The cost of a free bet is a related calculation. A free bet whose stake is not paid back is worth the free-bet amount times (odds minus 1) divided by odds, multiplied by the payout share of the market. A $10 free bet at 1.90 on a market with a 95% payout share is worth about $10 times 0.90/1.90 times 0.95, or about $4.50. That is the offer’s value in expectation, not its payout on a win; a winning bet pays the odds times the stake ($19 on a $10 free bet at 1.90), but the free bet’s own cost is the difference between the headline value and the expected value. The punter who treats a $10 free bet as a $10 stake is a punter who has miscounted.

The cost of a Same Game Multi is the same calculation with a wider margin. A three-leg multi with correlated legs at an average margin of 10% per leg returns about $0.90 of every $1 staked across all outcomes, against about $0.95 for a single bet at the same price. The wider margin on a multi is the bookmaker’s charge for the correlation; the punter’s saving from the higher price is the punter’s own calculation, and the two do not always come out the same way.

Frequently asked questions

How do bookmakers calculate odds?

Bookmakers start from a probability for each outcome and build in a margin on top. A two-way market at 1.90 / 1.90 has a probability of just over 50% on each side before the margin, and a margin of about 5% once the book is balanced. The wider the margin, the more the bookmaker keeps of every stake; the punter pays the margin on every bet, win or lose.

How does a punter get an edge in football betting?

The edge in football betting is in the price and in the selection, not in a system. A punter who prices markets across more than one brand and stakes only when the price is sharper than the true probability has an edge; a punter who bets on every match has the bookmaker’s margin as their only certainty. In New Zealand, only TAB NZ may lawfully take the bet, which closes the cross-brand price shop to the legal market.

What does it take to start a bookmaker in New Zealand?

It takes a change in the law. Section 74AAA of the Racing Industry Act 2020 closes the route to a second lawful provider for racing and sports betting, and there is no licence register for bookmakers because the section does not contemplate one. The Online Casino Gambling Act 2026 is a separate statute for online casino gambling; it does not open sports or racing betting to anyone other than TAB NZ.

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

TAB NZ, through its two online brands TAB and Betcha, is the only operator that may lawfully take a sports or racing bet from a person in New Zealand. The position has held since 28 June 2025, when section 74AAA of the Racing Industry Act 2020 took effect. Every other brand a New Zealand punter meets on a comparison site is, by definition, not licensed here, no matter what it calls itself.

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

The return on a winning single bet is the stake multiplied by the decimal odds. A $10 stake at 1.90 returns $19, of which $9 is net profit. A combination bet multiplies the legs into one price, so a three-leg multi at 1.50, 1.80 and 2.00 is a single bet at 5.40, and a $10 stake returns $54 on a win. The bookmaker’s margin is already inside the odds, and it is paid on every bet, win or lose.

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

The margin is the share of every stake the bookmaker keeps on average, win or lose. It sits inside the odds, and it shows up when the reciprocal of the odds on every outcome of a market are summed together: if the sum is below 1, the market is overround and the bookmaker has a margin. A two-way market at 1.90 / 1.90 has a margin of about 5%; a Same Game Multi with three legs has a margin closer to 10%. The wider the margin, the more the bookmaker keeps; the punter pays the margin on every bet.
