Best Bookmakers in New Zealand: What the Market Looks Like in 2026
New Zealand runs on a different kind of bookmaker market from the rest of the English-speaking world. Since 28 June 2025, only two online brands — TAB and Betcha, both run by TAB NZ — may lawfully take a racing or sports bet from a person in New Zealand. The Racing Industry Amendment Act 2025 inserted section 74AAA of the Racing Industry Act 2020 to put that position beyond argument, and the Department of Internal Affairs told unlicensed providers to withdraw with immediate effect. There is no licence register for bookmakers in New Zealand, because there is only one lawful operator to register. Every other brand a New Zealand punter meets — 22Bet, BetAlright, Sportaza, Winz.io and the rest of the names in the offshore space — operates outside that regime.

That shape decides what the rest of this page is for. The point of a “best bookmakers” guide in New Zealand is not to crown an offshore champion. It is to make clear who the lawful operator is, what it actually offers, and what the offshore alternative costs the punter in protections that are simply not there. Read as a choice: TAB and Betcha sit at the centre, with every other brand positioned by what they cannot give a New Zealand customer.
Data current as of 26 October 2026, verified against the Department of Internal Affairs register of TAB NZ’s two online brands and the Racing Industry Act 2020 (as amended).

The Landscape: One Operator, Two Brands, Many Offshore Names
The New Zealand market is a monopoly dressed as a choice. TAB NZ runs two online brands — TAB and Betcha — and that is the full list of lawful bookmakers for racing and sports bets taken over the internet from people in New Zealand. The offshore names that turn up in global rankings are not licensed here and have no application path to become so, because no licence route exists. The Department of Internal Affairs confirmed that the Racing Industry Amendment Act 2025 removed the application framework and that TAB NZ alone fills the slot.

A useful way to read the market is in three concentric rings. The inner ring is TAB NZ, the only operator with standing under section 74AAA, and it operates two customer-facing sites so punters can pick the brand they prefer. The middle ring is offshore brands a New Zealand punter will meet through affiliates, sport coverage or word of mouth — they take bets in plain sight but operate on Curaçao, Anjouan or Tobique paperwork, which holds no New Zealand authorisation. The outer ring is everything else: brand new sites, crypto-only books, casino brands that bolted on a sportsbook. None of them change the legal position. None of them extend the player’s options under New Zealand law.
That is the choice the rest of the page works through.
The Statutory Frame: Section 74AAA and What It Actually Says
The Racing Industry Act 2020 was amended by the Racing Industry Amendment Act 2025 to insert section 74AAA. The section makes it unlawful for any person other than TAB NZ to 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 change took effect on 28 June 2025, and the Department of Internal Affairs told operators serving New Zealand customers to withdraw with immediate effect.

The Gambling Act 2003 sits behind the Racing Industry Act as the broader statute, and the Department of Internal Affairs is the regulator under both. Inland Revenue administers the gambling-duty side of the offshore market and collects the Problem Gambling Levy. The Advertising Standards Authority’s Gambling Advertising Code covers how TAB NZ can advertise in New Zealand: ads must not be aimed at children (under 14) or young people (under 18), judged by context and audience, and a 25 per cent share is the threshold at which the audience becomes “significant” for the rule. None of this licences an offshore operator to advertise in New Zealand. The offshore operators that target Kiwi customers are doing so without any of those guardrails.
Two related statutes are worth knowing because they shape what is and is not on offer. The Online Casino Gambling Act 2026 creates a licensing regime for online casino gambling but it does not open sports betting to anyone other than TAB NZ. Greyhound racing is being wound down in stages from 1 August 2026, and from that date offshore operators may not take bets on greyhound races either, on top of the existing prohibition.
A final statutory point. Section 19(4) of the Gambling Act 2003, inserted in 2025, says an individual may not be convicted for placing a bet with an offshore betting operator in breach of section 74AAA. The New Zealand law targets the operator; no published penalty for a player was found. DIA warns of the risks — overseas operators may be in jurisdictions with minimal consumer safeguards, may not return unspent credits and may not pay out large wins — but no source states that a player is criminally liable for the act of betting.
Entain’s Partnership: Why TAB NZ Looks the Way It Does
TAB NZ’s operation is run by Entain under a 25-year agreement signed in 2023. The headline shape of the deal: Entain handles the platform and trading side, and TAB NZ keeps the customer-facing monopoly and the racing-industry funding stream. Entain takes a 50/50 share of gross profits, with at least NZ$150 million a year going to TAB NZ for the first five years, and the partnership included a one-off NZ$100 million payment from Entain to the racing sector. The agreement is the reason the platform, app and Same Game Multi product feel modern even though the underlying monopoly is unchanged from a generation ago.
The interesting point for the punter is what this changes and what it doesn’t. It changes the technology: TAB NZ’s app was first released on 8 September 2014 and has been rebuilt since, with Trackside live race streaming, in-app betting, Blackbook and Jockey Challenge tools, racing form data and a simplified wallet. It does not change the choice. The customer still has TAB NZ, in two brand skins. The partnership funds the platform, not the opening of the market.
What TAB NZ and Betcha Actually Offer
Both brands sit on the same TAB NZ back end and the same wallet, so the difference is product surface, not account.
TAB is the longer-established brand. The app covers horse and harness racing, rugby union, rugby league and other sports, pre-match and live, with a 17+ App Store age rating (the app also states customers must be 18 or over to bet — a betting rule, not an app-store rule). The Same Race Multi, Same Game Multi and Popular Multi products are TAB NZ’s response to the multi-leg bet that has dominated the global market. Place Extra is a TAB NZ-only nuance that lets punters back runners to finish as far back as tenth in selected races — a long-tail bet that makes sense in deep fields but does not exist in most offshore books. Trackside live race streaming and in-app betting come on the racing side.
Betcha is positioned as the younger, more digital-native skin of the same operation. The betting products are the same in shape (Win, Place, Each Way, Quinella, Exacta, Trifecta, First Four, Quaddie, Big6, plus the multis) and the wallet is shared. The difference is brand tone and onboarding, not pricing or market depth. A punter who likes the Betcha app and wants to bet on Melbourne Cup or All Blacks tests has the same odds and the same limits as a punter using the TAB app.
The combined product set is, by global standards, narrow. TAB NZ does not run a sportsbook with the breadth of a global Tier-1 book on Premier League, NBA or Champions League. It runs the racing and rugby first, with the international sports layered on. That is a deliberate product choice tied to the monopoly, and a punter whose interest is exclusively in, say, European football will notice the gap.
Bonuses and “Bonus Bets”: What the Marketing Words Conceal
TAB NZ runs “bonus bets” promotions rather than deposit bonuses. New TAB NZ customers can receive Bonus Cash that can be split across multiple bets, and the app lists a Mega Multi bonus of up to NZ$50 in Bonus Cash when a multi of four or more legs falls short by a set number of legs — terms and conditions apply. The detail in those terms decides whether the offer is worth taking, and that detail is on TAB NZ’s own page, not here.
Three rules apply across the bonus-bet product. First, a bonus bet that is paid out as Bonus Cash is usually not paid out as cash on a win: the stake is forfeit, the same as a free bet at any offshore book. Second, the “up to” figure is a ceiling, not a default — the size of the bonus depends on the deposit, the bet placed and the offer running that week. Third, an accumulator-style offer that pays out when a multi “falls short by a set number of legs” is a partial-loss refund, not a win: it returns something on a losing bet, but the original stake is still exposed.
For the offshore bookmakers the same pattern holds, with extra twists. A “200% up to 1 BTC” welcome offer sounds outsized until the wagering factor is read: turnover requirements typically run between 5x and 40x the bonus, minimum-odds clauses knock out the obvious singles, and a cap on free-bet winnings turns a long-priced winner into a clipped payout. The marketing word is one figure; the realised value is another, and the realised value is what the punter walks away with.
The most useful line a punter can take into any bonus offer, TAB NZ or offshore, is this: read the wagering factor, the minimum odds and the expiry before reading the headline number. The headline number is what the marketing team writes first; the wagering factor is what the punter pays for.
Safer Gambling in New Zealand: Tools and the Limits of the Framework
The safer-gambling tools the offshore space offers are inconsistent; the tools TAB NZ offers are listed in its app and cover the basics. TAB NZ’s app lists deposit limits, time-outs and self-exclusion, and a self-exclusion applies across both TAB NZ brands. The free Gambling Helpline is 0800 654 655, with a text line at 8006, and Safer Gambling Aotearoa is the wider service behind the line.
Two limits on the framework are worth naming. There is no single national online-betting exclusion register: the register the Online Casino Gambling Act 2026 will require is for online casinos only. And the age for TAB NZ betting is 18; land-based casinos in New Zealand are 20. A punter who turns 18 and starts betting with TAB NZ is in a different age bracket from the punter who walks into a SkyCity casino two years later, and the protections around them are different in law as well as in practice.
The wider harm-minimisation work is funded by the Problem Gambling Levy, set at 0.74 per cent and in force from 1 July 2025 to 30 June 2028. That levy sits on TAB NZ and is part of the picture of why the monopoly exists: it is a single operator with a single harm-minimisation budget, rather than a fragmented market where each operator pays a fraction. Offshore operators do not pay the levy, do not contribute to Gambling Helpline funding and do not have to integrate with the Safer Gambling Aotearoa tools.
Crypto, Anonymity and the Offshore Reality
The offshore brands New Zealand punters meet lean hard on crypto. Roobet and Thunderpick run on crypto rails as a default, and brands like Winz.io, Sportaza and LegendPlay list Bitcoin, Ethereum and USDT as deposit methods. The pitch is speed, low fees and a degree of pseudonymity that a bank transfer does not give.
The cost of that pitch sits in the next breath. A crypto account at an offshore book is not subject to New Zealand harm-minimisation tools, the Gambling Helpline, the Problem Gambling Levy or the Department of Internal Affairs’ complaints framework. No source establishes a New Zealand rule against crypto use on betting sites, but the lack of a rule is not the same as the existence of a protection. The wallet-to-wallet flow that makes crypto attractive is also the flow that sits outside the protections that the New Zealand framework provides.
The crypto brands most often named in New Zealand-facing affiliate material are Curaçao-licensed (Roobet under OGL/2024/687/0427, Thunderpick under OGL/2024/677/0722) or Anjouan-licensed (Sportaza under ALSI-202606064-FI2, with its terms also citing Tobique licence 0000067; LegendPlay under an Anjouan Gaming Authority licence). Curaçao and Anjouan paperwork conveys no legal standing to offer bets in New Zealand. It is operator-side authorisation in the country that issued it, not consumer-side protection in the country where the punter sits.
Payments and Payout Speed at TAB NZ
TAB NZ’s published deposit methods are operator-level and are not generalised here: they come from the TAB NZ help pages and the app’s simplified wallet. The relevant point for the punter is that the wallet is one tab, one balance, one set of deposit and withdrawal methods across the TAB and Betcha skins. There is no separate top-up for the two brands and no separate withdrawal queue.
The offshore alternatives run on a wider list of methods: cards, e-wallets (Skrill, Neteller, MiFinity), bank transfer, prepaid vouchers and a long crypto tail. The pitch is breadth, the practice is uneven: a brand that lists twenty deposit methods often runs withdrawals through three. The most common friction points the offshore punters report are withdrawal delays on first cash-out (KYC re-checks), declined card deposits that route through a third country and currency-conversion spreads that show up only on the statement. None of these are New Zealand-specific issues; they are the cost of the offshore path the section on Entain’s partnership called out.
The TAB NZ App and Mobile Betting
TAB NZ’s app, listed as “TAB – Racing & Sports Betting”, is published on the New Zealand App Store under the seller name New Zealand Racing Board, first released on 8 September 2014 and updated regularly. The 17+ App Store age rating is the store’s classification; TAB NZ’s own rule is 18 or over to bet.
The product surface that matters for in-play and mobile-first betting: Trackside live race streaming with in-app betting, racing form data, Blackbook and Jockey Challenge tools, Same Race Multis, Same Game Multis, one-tap Popular Multis, Place Extra and a simplified wallet. The combination is closer to a dedicated racing and multis app than a full sportsbook, and that is what TAB NZ is for. A punter whose primary interest is rugby union, rugby league and horse racing has everything in one place; a punter whose primary interest is, say, NBA or La Liga will use TAB NZ for the occasional bet and look offshore for depth.
Bet Types, Odds and the Margin: How the Numbers Work
The simplest way to read the odds a bookmaker publishes is to remember that the bookmaker’s margin is built into the price. A two-way market at decimal odds 1.90 / 1.90 pays out 1.90 for every NZ$1 staked on either side, but the implied probability is 1 / 1.90 on each outcome — 52.63 per cent on each — and 52.63 + 52.63 adds up to 105.26 per cent. The 5.26 per cent over-round is the margin: what the bookmaker keeps, on average, for every NZ$1 bet on this market. State the result as a band: a two-way market priced at 1.90 / 1.90 carries a margin of around 5.3 per cent; at 1.85 / 1.85 it climbs to roughly 8.1 per cent; at 1.95 / 1.95 it falls to roughly 2.6 per cent. The closer to 2.00 / 2.00 the prices are, the thinner the margin and the better the punter’s expected return across the market.
The same calculation applies to a three-way 1X2 football market or a horse race with eight runners. The odds sum to more than 100 per cent when converted to implied probability, and the over-round is the margin. The punter’s job is not to find markets with a 0 per cent margin (they do not exist), it is to find the bookmaker whose margin on the markets they bet on is thinner than the next book’s.
For a winning bet the arithmetic is simpler. A NZ$10 stake at decimal odds 2.10 returns NZ$21 — NZ$10 of stake returned, NZ$11 of profit. A NZ$10 stake at odds 5.50 returns NZ$55 — NZ$10 stake, NZ$45 profit. The return is stake × odds; the net profit is stake × (odds − 1). For a combination bet the leg odds multiply: three legs at 2.00, 2.00 and 3.00 become a single price of 12.00, and the NZ$10 stake returns NZ$120 if all three land.
The same odds that decide a payout also decide the bookmaker’s edge. A punter who reads the prices as probabilities and watches the over-round is reading the same number the bookmaker is.
What the Comparison Looks Like for New Zealand
The standard “best bookmakers” ranking, applied as written to New Zealand, is not a ranking at all. TAB and Betcha are the same operator under different brand skins. The other names punters meet — 22Bet, Telbet, BetAlright, Glorion, LegendPlay, BigClash, Sportaza, Winz.io — are offshore brands that share a structure (Curaçao or Anjouan paperwork, an offshore holding company, a New Zealand-facing affiliate footprint) and a status (not licensed in New Zealand, no application route, no New Zealand complaints framework). They differ on product surface, crypto support and bonus shape, but not on the legal point.
That is what the comparison below reflects. The matters are the brand, the New Zealand status (TAB NZ brand or not licensed in New Zealand) and what the operator’s own terms state about how it operates. The table is descriptive, not a ranking; the verdict sits with the punter.
| Brand | New Zealand status | Operator’s own terms |
|---|---|---|
| TAB | TAB NZ brand | Run by TAB NZ under the Racing Industry Act 2020; 18+ to bet; one app, two brands |
| Betcha | TAB NZ brand | Same operator group as TAB; positioned as the digital-native skin |
| 22Bet | Not licensed in New Zealand | Curaçao licence 8048/JAZ, holder TechSolutions Group N.V. |
| Telbet | Not licensed in New Zealand | Crypto casino and sportsbook; 200% up to 1 BTC plus 50 free spins welcome offer |
| BetAlright | Not licensed in New Zealand | 18+ only; separate partners site at partnersbetalright |
| Glorion | Not licensed in New Zealand | Live chat and email support; 18+ only |
| LegendPlay | Not licensed in New Zealand | Anjouan Gaming Authority licence; 18+ only |
| BigClash | Not licensed in New Zealand | Curaçao licence 8048/JAZ; pre-match and live plus virtuals and esports |
| Sportaza | Not licensed in New Zealand | Anjouan licence ALSI-202606064-FI2; terms cite Tobique 0000067 |
| Winz.io | Not licensed in New Zealand | Anjouan and Tobique licences, holder Novatrix SRL |
Operator Reviews: What Each Brand Actually Is
TAB
TAB is the longer-established of TAB NZ’s two online brands, listed as “TAB – Racing & Sports Betting” on the New Zealand App Store and first released on 8 September 2014. The product surface is racing-first: horse and harness racing, rugby union and rugby league, plus a layer of international sports, pre-match and live. The Same Race Multi, Same Game Multi, Popular Multi and Place Extra products sit on top of the standard Win, Place, Each Way, Quinella, Exacta, Trifecta, First Four, Quaddie and Big6 markets. Trackside live race streaming and in-app betting are bundled into the racing side; racing form data, Blackbook and Jockey Challenge tools sit beside it.
The licence position is unique in New Zealand: TAB is one of the two lawful online brands under section 74AAA, with no application route for any other brand to take its place. The safer-gambling tools (deposit limits, time-outs, self-exclusion) are in the app, the Gambling Helpline is 0800 654 655 and a self-exclusion applies across both TAB NZ brands. The bonus-bet product runs as Bonus Cash, with a Mega Multi bonus of up to NZ$50 in Bonus Cash when a multi falls short by a set number of legs (terms and conditions apply). For a punter whose primary interest is racing and New Zealand or Australasian sport, TAB is the only complete option the law allows.
Betcha
Betcha is the second of TAB NZ’s two online brands and shares the wallet, the racing and sports product and the back end with TAB. The brand is positioned as the younger, more digital-native skin: the onboarding and the app chrome lean into the multi-bet and Same Game Multi product, and the racing product is the same as TAB’s underneath. A punter who prefers Betcha’s interface has the same markets, the same odds and the same limits as a TAB punter, and the self-exclusion tool covers both brands.
The same licence position applies: Betcha is one of the two brands allowed to take online sports and racing bets from people in New Zealand under section 74AAA. The same harm-minimisation framework applies, and the same Department of Internal Affairs oversight applies. For a punter who wants the modern multi-bet interface over TAB’s older chrome, Betcha is the right skin to use; the choice between TAB and Betcha is a product-surface choice inside the one operator, not a market-creation choice.
22Bet
22Bet is the brand the Curaçao press has written about most often in 2025 and 2026. It 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 product surface is broad — a global sportsbook with pre-match and live markets across football, basketball, tennis and a long tail — and the affiliate footprint extends to New Zealand. None of that changes the New Zealand position: 22Bet is not licensed in New Zealand, only TAB NZ may offer racing and sports betting to people in New Zealand under section 74AAA, and a Curaçao licence is insufficient to offer bets here.
The punter-side cost of choosing 22Bet is the absence of the New Zealand framework: no New Zealand complaints route, no integration with the Gambling Helpline, no contribution to the Problem Gambling Levy. The operator-side cost is the legal exposure of taking bets from New Zealand customers in breach of section 74AAA. The price the brand charges the punter is the bonus and the market depth; the price the punter pays is the protections.
Telbet
Telbet describes itself as a crypto casino and sportsbook and lists a welcome offer of 200% up to 1 BTC plus 50 free spins on its Russian-language site, with a 5 USDT free bet attached. The crypto-first positioning is the headline; the Curaçao or equivalent licence underneath is the back office, and the brand names no licence that applies in New Zealand.
The same pattern holds as for 22Bet: not licensed in New Zealand, no application route, no New Zealand complaints framework. The crypto angle accelerates the deposit-and-withdrawal flow and pulls the operation further from any New Zealand oversight. A punter who wants Telbet for the crypto experience is paying for that experience with the absence of the New Zealand framework, on top of the legal exposure on the operator side.
BetAlright
BetAlright lists an 18+ age requirement on its home page and runs a separate partners site at partnersbetalright for affiliate integration. The product surface is a sportsbook plus casino combination, and the operator-side paperwork is an offshore licence that does not apply in New Zealand.
The New Zealand status is the same as the other offshore names: not licensed in New Zealand under section 74AAA, no application route, no New Zealand complaints route. The 18+ age requirement sits alongside the New Zealand 18+ rule but does not substitute for New Zealand harm-minimisation tools. A punter whose primary interest is the BetAlright product surface is making the same trade as with 22Bet and Telbet.
Glorion
Glorion lists Live Chat and email support on its About Us page, takes customers aged 18 and over, and runs a sportsbook and casino combination. The licence is offshore and does not apply in New Zealand.
The New Zealand cost of choosing it is the same as for the other offshore names: no New Zealand oversight, no New Zealand complaints framework, no integration with the Gambling Helpline. The marketing surface is operator-level, the protection surface is not New Zealand.
LegendPlay
LegendPlay runs an Anjouan Gaming Authority licence and accepts customers aged 18 and over. The product is a sportsbook plus casino combination in the same shape as the other offshore names on this list, with the Anjouan paperwork underneath.
The Anjouan licence is not recognised for New Zealand operations. The 18+ age requirement is the operator’s own rule and does not connect to New Zealand harm-minimisation tools. A punter choosing it over TAB NZ is choosing it with the same protections gap as the rest of the offshore cluster.
BigClash
BigClash runs a Curaçao licence under 8048/JAZ and offers pre-match and live sports betting across international and local leagues, plus virtual sports and esports betting on FPS and MOBA titles. The virtuals and esports angle is the product differentiator; the offshore licence is the legal position underneath.
New Zealand status is the same as the rest of the offshore cluster: not licensed in New Zealand, no application route, no New Zealand complaints framework. The esports and virtuals line is a depth that TAB NZ does not match, but the protection cost is the same as for the other Curaçao names on the list.
Sportaza
Sportaza’s footer states it is licensed and regulated by the Government of the Autonomous Island of Anjouan, Union of Comoros, under licence ALSI-202606064-FI2; its terms (section 1.4) cite licence 0000067 issued by Tobique. The product is a sportsbook plus casino combination with the long market tail that the offshore space offers.
The dual-licence paperwork does not change the New Zealand position: not licensed in New Zealand under section 74AAA, no application route, no New Zealand complaints framework. A punter choosing Sportaza for the breadth of the sportsbook is making the standard offshore trade.
Winz.io
Winz.io states in its footer that it holds a licence delivered by Anjouan and Tobique. The product surface is the offshore-cluster standard: sportsbook, casino, the long tail of markets and the same crypto-friendly deposit options.
The New Zealand cost is the same as for the other offshore names: no New Zealand oversight, no New Zealand complaints route, no integration with the Gambling Helpline. The marketing surface is operator-level, the protection surface is not New Zealand. A punter choosing Winz.io for the crypto experience is paying the same trade-off as with Telbet, with the same Anjouan paperwork underneath.
The Verdict on Each Path
The choice the New Zealand punter faces is not a choice between ten roughly-equivalent bookmakers. It is a choice between two paths, each with its own shape.
The first path is the lawful one: TAB and Betcha, both operated by TAB NZ, both covered by the Racing Industry Act 2020 and the Department of Internal Affairs’ oversight, both integrated with the Gambling Helpline and the Safer Gambling Aotearoa tools. The product surface is racing-and-rugby-first with international sport and live markets layered on. The safer-gambling tools are in the app. The bonus-bet product is Bonus Cash with the usual turnover and minimum-odds clauses. For a punter whose primary interest is racing, rugby, cricket and the Australasian sport the law was built around, TAB NZ is the right answer because it is the only answer the law allows.
The second path is the offshore one: 22Bet, Telbet, BetAlright, Glorion, LegendPlay, BigClash, Sportaza, Winz.io and the long tail. The product surface is broad, the bonus headlines are big, the crypto rails are fast. The protection surface is not New Zealand: no New Zealand complaints framework, no integration with the Gambling Helpline, no Problem Gambling Levy contribution, no Department of Internal Affairs oversight. For a punter whose primary interest is the breadth of an offshore sportsbook and who is comfortable operating outside the New Zealand framework, the offshore path is a real option — with the legal exposure on the operator side and the absence of the framework on the punter side.
The read that fits both paths is the same. TAB NZ is the only operator with a standing under section 74AAA, and the offshore brands are an alternative, not a substitute. The “best bookmaker” framing on this page is the framing of an open market; the New Zealand market is not open, and the framing has to bend to that.
A Note on Tax, Advertising and What Stays Outside This Page
Two final pieces of context, both worth knowing but neither the heart of this page. On tax, Inland Revenue guidance says recreational gambling winnings are generally not taxable and prize money from TAB horse, dog and trotting races is not taxable; a person who bets as a business is a different case, and the right source for that is Inland Revenue or an accountant. On advertising, the Advertising Standards Authority’s Gambling Advertising Code applies to betting advertisements in New Zealand, with audience-threshold and content rules but no New Zealand equivalent of a “whistle-to-whistle” ban for betting ads. Neither of these points changes the choice between the two paths; they sit alongside it.
Frequently Asked Questions
How do bookmakers calculate odds?
A bookmaker builds the margin into the prices it shows. For each outcome of a market, the decimal odds imply a probability (1 / odds), and those implied probabilities are made to add up to more than 100 per cent. The over-round — the difference between the implied-probability total and 100 per cent — is the bookmaker’s margin: what the book keeps, on average, for every dollar bet on the market. A two-way market priced at 1.90 / 1.90 carries a margin of around 5.3 per cent; at 1.85 / 1.85 it climbs to roughly 8.1 per cent; the closer to 2.00 / 2.00, the thinner the margin and the better the punter’s expected return across the market.
How is the return on a bet worked out from the stake and the odds?
The return on a winning bet is stake × odds, and the net profit is stake × (odds − 1). A NZ$10 stake at decimal odds 2.10 returns NZ$21 — NZ$10 stake, NZ$11 profit. A NZ$10 stake at odds 5.50 returns NZ$55 — NZ$10 stake, NZ$45 profit. For a combination bet the leg odds multiply: three legs at 2.00, 2.00 and 3.00 become a single price of 12.00, and a NZ$10 stake returns NZ$120 if all three land.
What is the bookmaker’s margin and how can it be seen in the odds?
The margin is the bookmaker’s built-in edge, expressed as a percentage of every dollar bet on a market. To see it, convert each decimal price to an implied probability (1 / odds), add those probabilities together and subtract 100 per cent. The result is the margin. A 1X2 football market priced at 2.10 / 3.40 / 3.50 has implied probabilities of 47.6 + 29.4 + 28.6 = 105.6 per cent, and the 5.6 per cent over-round is the margin. A thinner margin means more of each dollar returns to punters, on average, across the market.
Which bookmaker may lawfully take sports and racing bets in New Zealand?
TAB and Betcha, both run by TAB NZ, are the only online brands that may lawfully take a racing or sports bet from a person in New Zealand. The Racing Industry Amendment Act 2025 inserted section 74AAA of the Racing Industry Act 2020, in force since 28 June 2025, and the Department of Internal Affairs told unlicensed providers to withdraw with immediate effect. There is no licence route for any other bookmaker and no licence register for bookmakers, because there is only one lawful operator.
How does a punter start with TAB NZ?
Account opening at TAB NZ requires a verified New Zealand address and ID, an age of 18 or over (betting under 18 is an offence under section 89 of the Racing Industry Act 2020), and a deposit through one of the operator-level payment methods listed in the TAB NZ help pages. The simplified wallet holds the balance across both TAB NZ brands, the safer-gambling tools (deposit limits, time-outs, self-exclusion) are set up in the app, and the Gambling Helpline is 0800 654 655 if a punter wants support before opening an account or at any point afterwards.
