26 October 2026 — figures and operator claims cross-checked against the Department of Internal Affairs register and the TAB NZ app listing.

The “best bookies in New Zealand” question has a shorter answer than the search results suggest. Since 28 June 2025, the Racing Industry Amendment Act 2020 (now folded into the Racing Industry Act 2020) has barred anyone other than TAB New Zealand from offering sports or racing bets to a person in New Zealand. The two online brands that survive that change are TAB and Betcha — both run by TAB NZ, neither a rival to the other. Every other brand a Kiwi punter meets in a search results page is an offshore operator selling into a market it has no lawful route into.

That makes this page unusual. There is no Top-10 ladder to climb, no licence register to scan for a Curaçao or MGA tick that means something here, and no comparison grid in which all ten rows compete on equal terms. TAB and Betcha are the lawful options; the rest sit beside them only because Kiwi punters meet them, not because they belong on the same shelf. The angle of this guide is the choice itself — what the lawful route looks like in practice, what it costs the punter in margin and bonus terms, and what an offshore brand actually delivers if a reader still goes that way.

New Zealand’s betting monopoly: what section 74AAA actually does

The Racing Industry Amendment Act 2025 inserted section 74AAA into the Racing Industry Act 2020. The clause is short and absolute: no person other than TAB New Zealand 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) is the regulator that polices the prohibition, and on the day the section came into force it instructed providers serving New Zealand customers to withdraw with immediate effect.

There is no bookmaker licence to apply for. There is no register of licensed bookmakers because there is only one lawful provider. The same monopoly reaches events held inside and outside New Zealand, so a bet on the All Blacks in Auckland and a bet on the Champions League final in Munich both flow through TAB NZ if the punter is in New Zealand. The Online Casino Gambling Act 2026, which sets up a licensing regime for online casino games, does not extend the monopoly and does not change it: a casino licence is a casino licence, not a sports-betting licence.

What the law targets is the operator, not the punter. Section 19(4) of the Gambling Act 2003 (inserted in 2025) states that an individual cannot be convicted for placing a bet with an offshore operator in breach of section 74AAA, so no published player penalty exists. The offshore operator, on the other hand, is breaking New Zealand law simply by accepting the bet, and the absence of a prosecuted case so far is not the same as a green light. The honest framing is plain: TAB NZ and Betcha are the only lawful options, with New Zealand harm-minimisation tools and a complaints route that reaches a New Zealand body; offshore brands sit outside that frame, with DIA’s stated risks — operators may be in jurisdictions with minimal consumer safeguards, may not return unspent credits, and may not pay out large wins — and limits a punter may have to chase through a foreign complaints process.

TAB NZ does not stand alone. In 2023 it signed a 25-year operating partnership with Entain, the global betting group behind Ladbrokes, Coral and Neds. Entain runs the TAB business day to day, takes a 50/50 share of gross profits from the partnership, and has pledged at least $150 million a year to TAB NZ for the first five years of the deal, plus a one-off $100 million payment to the racing sector. The monopoly is as such a public-private operation, not a state-run bookmaker in the old sense, but it remains a monopoly for the punter: the bet still goes through TAB NZ’s rails, the betting rules still come from TAB NZ, and the only consumer-facing split is between the TAB brand (positioned around racing, with a deeper form and trackside product) and the Betcha brand (positioned around sports and a younger, app-first audience).

Player protection in a one-operator market: what TAB NZ actually offers

A monopoly does not mean protection is optional. TAB NZ is required to keep the risks of problem and underage gambling minimised under the Racing Industry Act 2020, and it pays a Problem Gambling Levy of 0.74% into the Ministry of Health’s harm-minimisation funding (the current rate applies from 1 July 2025 to 30 June 2028). The age for a TAB NZ account is 18; the app carries a 17+ App Store rating but the operator’s own terms make 18 the binding minimum, and betting under 18 is an offence under section 89 of the Act. Land-based casinos in New Zealand set the bar at 20, but that rule does not transfer to betting: 18 for the TAB, 20 for the casino floor, never the same number.

TAB NZ’s app carries three safer-gambling tools as standard. Deposit limits let a punter cap how much can land in the wallet over a chosen period, with the cap set inside the app and a cool-down before any increase takes effect. Time-outs are short self-exclusion windows of a few days up to a few weeks, used when the punter wants a break without committing to a longer block. Self-exclusion closes the account for a chosen period — months or years — and applies across both TAB and Betcha, because both brands sit on the same TAB NZ account. A punter who excludes themselves from TAB is excluded from Betcha at the same time, and the exclusion cannot be lifted early.

The free New Zealand Gambling Helpline (0800 654 655, text 8006) and Safer Gambling Aotearoa are independent services, not part of TAB NZ, and the app lists them alongside the in-app tools. There is no single national online-betting exclusion register: the register that the 2026 online casino law will set up covers online casinos only. Greyhound racing is closing in stages from 1 August 2026, and from that date offshore operators may not take bets on greyhound races either, because the prohibition in section 74AAA reaches greyhound racing the same way it reaches thoroughbred and harness.

What a New Zealand punter can actually bet on

TAB NZ takes fixed-odds bets and tote (pool) bets. The racing menu is the deepest in the country by a margin: thoroughbred, harness (trots), and greyhound meetings from New Zealand and Australia, with Trackside live race streaming and in-app betting that lets a punter move from the form to the bet slip without leaving the stream. Same Race Multis let a punter combine several runners from one race into one bet; Same Game Multis do the same for a single sports event. One-tap Popular Multis are pre-built combinations the app surfaces for big meetings. Place Extra extends the place payout to runners finishing up to tenth in selected races, which is a more generous each-way than a standard place bet.

The sports menu runs from rugby union and rugby league (All Blacks, Super Rugby Pacific, NRL) through football, cricket (Black Caps, IPL, international calendar), basketball, tennis, and the major US leagues. Live betting is in the app, with odds updating through the event, and the Same Game Multi builder extends into live markets on the bigger fixtures. The 2026 law treats virtual (computer-simulated) sport as casino gambling, not sports betting, so the virtual tab inside the casino product is a different licence category from a rugby league multi. Whether esports counts as “sports betting” under the Racing Industry Act is not established; the app’s esports lines live in the sportsbook section today, but the legal classification sits in a grey area that a punt on a CS2 final does not resolve.

Bets on politics, novelty markets (reality TV, awards), and spread betting are not established as part of the TAB NZ offer. There is no statutory per-bet cap, so any stake ceiling a punter meets comes from TAB NZ’s own terms, not from the law. No New Zealand-licensed betting exchange exists; a punt on a peer-to-peer platform is not a lawful New Zealand bet, and the same section 74AAA prohibition that covers bookmakers reaches any other operator taking bets from a person in New Zealand.

Reading the odds: how the bookmaker’s margin sits inside every price

A decimal price of $2.10 on a head-to-head market says the operator will pay back $2.10 for every $1 staked if the runner wins — return = stake × odds, net profit = stake × (odds − 1). For a Same Game Multi with four legs at $2.20, $1.80, $1.95 and $2.50, the combined price is the four numbers multiplied together: 2.20 × 1.80 × 1.95 × 2.50 = $19.31, so a $5 stake returns $96.55 if all four legs win. The arithmetic is the same for racing and sports, the only difference being the racing-specific bet types (quinella, exacta, trifecta, First4, quaddie, Big6) which pay a dividend declared after the pool closes rather than a price declared before the bet.

The price does not sit on its own. A bookmaker’s margin is the share of every dollar bet on a market that the bookmaker keeps on average across all outcomes. It is built into the prices themselves, and it can be read off a market by converting each price back to an implied probability (1 ÷ odds) and summing the implied probabilities across the market: a fair market with no margin sums to 1.00, a real market sums to something above 1.00, and the gap above 1.00 is the margin.

A worked example on a two-way market at $1.90 / $1.90 — illustrative, not a quoted TAB NZ price — gives an implied probability of 1 ÷ 1.90 = 0.5263 on each side, summing to 1.0526. The payout share is 1 ÷ 1.0526 = 0.9500, so the margin is 1 − 0.9500 = 0.0500, or 5.0%. If the same two-way market is priced $1.85 / $1.85, the implied probabilities are 1 ÷ 1.85 = 0.5405 on each side, summing to 1.0811, with a payout share of 1 ÷ 1.0811 = 0.9249 and a margin of 7.5%. As a band, that places a typical two-way market in the 5–7% margin range, and the more exotic the market (handicap lines, alternative totals, player props) the wider the band tends to push.

The same arithmetic on a three-way 1X2 football market (home / draw / away) — typical TAB NZ prices for an All Whites friendly might be $2.40 / $3.20 / $2.90 — gives implied probabilities of 0.4167 + 0.3125 + 0.3448 = 1.0740, a payout share of 1 ÷ 1.0740 = 0.9311, and a margin of about 6.9%. Tote and pool products carry no bookmaker margin in the same sense; the take is the operator’s commission on the pool, declared after the race, and it is usually smaller than a fixed-odds margin but more variable.

The practical use of the calculation is straight. Two bookmakers offering the same head-to-head market at $1.90 are not offering the same deal if one of them carries a wider margin on the wider market; a punter who shops by single price misses the bigger number sitting behind the visible one. A multi bet compounds the margin of every leg into the combined price, which is why a $19.31 multi looks generous on the ticket and quietly keeps more of the stake than a sequence of singles might. And the promo price — “boosted odds”, “best odds”, “price promise” — is the operator’s way of giving back a sliver of the margin it may otherwise keep; the gift is real, but the slice it comes from was the operator’s to start with.

What a TAB NZ welcome offer actually costs

A “Bonus Cash” offer is the TAB NZ welcome product for new accounts, paid as a credit rather than a cash refund, and split across multiple bets rather than handed over as a single lump. The published mechanic on the app includes a Mega Multi bonus that pays up to $50 in Bonus Cash when a multi of four or more legs falls short by a set number of legs — the closer the multi gets to a winner, the bigger the bonus, which is a softer form of accumulator insurance than a strict “money back if one leg lets you down”.

The cost of an offer like this lives in three numbers, all of which sit in TAB NZ’s own terms rather than in the marketing. The first is the qualifying requirement: what the punter has to do to unlock the bonus (first deposit, first settled bet, opt-in via the app). The second is the wagering condition: how much the bonus has to be turned over, on what kind of markets, at what minimum price, before any winnings become withdrawable. The third is the cap on what the bonus can pay out, and the deadline by which the wagering has to be completed.

A bonus of, say, $50 in Bonus Cash with a 3× turnover requirement on the bonus at minimum odds of $1.50 means a punter has to place $150 of qualifying bets at odds of $1.50 or longer before any winnings become cash. If the average margin on the qualifying markets is 6%, the expected cost of clearing the bonus is $150 × 0.06 = $9.00, so the offer is worth $50 − $9.00 = $41.00 in expected value before any cap or deadline bites. A punter who only plays exotics at 8% margin pays $150 × 0.08 = $12.00 to clear the same bonus, walking away with an expected value of $38.00 — still positive, but smaller. A punter who plays the minimum-odds markets exactly and runs out of time before clearing has paid $150 in qualifying bets and earned nothing.

The headline number is always the biggest number on the page. The wagering requirement is the number that decides whether the offer is worth the qualifying bet, and the minimum price is the number that decides whether the punter can clear it on the markets they actually wanted to play. Read all three before deciding, and never chase a bonus whose wagering requirement is longer than the time the punter was going to spend on the sport anyway.

The choice that is not on the table

New Zealand punters who search for “best bookies” usually want to compare a shortlist. The shortlist this market allows has two entries, both inside the same group. TAB and Betcha are the two online brands of TAB NZ, run by the same operating company, on the same rails, with the same licence behind them. They are not rival bookmakers, and any page that lines them up as if they were competing on price is misrepresenting what they are. The split between the brands is a marketing split, not a margin split: TAB carries the deeper racing form, the Trackside product, and the older retail-style punter; Betcha carries a sports-led product, a younger look, and the same multi builders and live markets underneath.

A punter who wants to bet with TAB NZ as such chooses a brand, not a bookmaker. TAB is the right pick if the meeting on the screen is a Saturday at Trentham or a Friday night harness card from Addington, and the punter wants the form, the Blackbook tools, and the Trackside stream underneath the bet slip. Betcha is the right pick if the meeting is a Champions League night or an NBA slate, and the punter wants the Same Game Multi builder sitting at the front of the screen. Both brands feed the same wallet, both honour the same self-exclusion, and both clear into the same TAB NZ safer-gambling tools.

The offshore brands a Kiwi punter meets on a search results page — RoyalistPlay, Glorion, Telbet, Alawin, Thunderpick, 22Bet, BigClash, Sportaza, and the wider set that includes Boomerang Bet, Baji, Betninja, Roobet, LunuBet, Paripesa, LegendPlay, RoosterBet, BillyBets, SpinBetter and others — sit outside the lawful frame. Several of them hold licences from Curaçao, Anjouan, Tobique, or Costa Rica; none of those licences authorise taking bets from a person in New Zealand, and none of them put a New Zealand complaints route, a New Zealand harm-minimisation framework, or a New Zealand self-exclusion register in reach. The brands are described and rated below so a Kiwi punter can see what they actually offer, but the rating is not a recommendation to sign up.

Review: TAB NZ’s two brands and ten offshore names

The comparison below covers the two lawful New Zealand bookmakers first and ten offshore brands second. Each brand carries a New Zealand status (TAB NZ brand or not licensed in New Zealand) and a note on what the operator’s own terms state about the subject. The grouping matters: the two TAB NZ brands belong together because they are one operator group, and the offshore brands belong together because none of them has any lawful standing in New Zealand. A brand’s row does not compete with another row’s row on price or bonus, because the comparison is between two different propositions — one lawful, one not.

(Note: the table above lists TAB, Betcha, and a sample of offshore operators Kiwi punters commonly encounter; the wider review section below rates the specific brands research covered.)

TAB (TAB NZ brand)

TAB is the older of TAB NZ’s two online brands and the one that carries the depth of the racing product. The racing menu is the deepest in the country by a wide margin: thoroughbred meetings from New Zealand and Australia, harness (trots) from both sides of the Tasman, greyhound meetings (until greyhound racing closes in stages from 1 August 2026), and a tote product that pays out a declared dividend after each race rather than a fixed price. Trackside live race streaming sits inside the app with in-app betting, so the form, the race, and the bet slip share one screen. Same Race Multi lets a punter combine runners from one race into a single bet, and Place Extra extends the place payout to runners finishing up to tenth in selected races — a more generous each-way than a standard place bet.

The sports menu runs from rugby union and rugby league through football, cricket, basketball, tennis, and the major US leagues, with the same Same Game Multi builder the sports-led brand (Betcha) carries. Live betting is in the app on the bigger fixtures, with odds updating through the event. The welcome offer is paid in Bonus Cash, split across multiple bets, and includes a Mega Multi bonus for multis that fall one or two legs short.

The safer-gambling tools sit inside the app: deposit limits, time-outs, and self-exclusion, with self-exclusion applying across TAB and Betcha at the same time. The free Gambling Helpline (0800 654 655, text 8006) is listed alongside the in-app tools. TAB NZ pays the Problem Gambling Levy (0.74%, in force from 1 July 2025 to 30 June 2028) and is required to keep the risks of problem and underage gambling minimised under the Racing Industry Act 2020.

The right pick for a punter whose main interest is racing — form, the Blackbook, Jockey Challenge, the Trackside stream — and who wants the deeper racing product underneath the sports tab.

Betcha (TAB NZ brand)

Betcha is the second of TAB NZ’s two online brands, positioned around sports and a younger, app-first audience. The sports menu leads the screen, with the Same Game Multi builder at the front and the live markets sitting one tap away. The racing menu is present but shallower than TAB’s: the meeting list is there, the win / place / each-way bets are there, but the Trackside stream and the deeper form tools are TAB’s, not Betcha’s. Betcha is the sports-led brand of the same operator group, not a separate bookmaker.

The welcome offer, the safer-gambling tools, and the underlying TAB NZ account are the same as TAB’s, because both brands run on the same TAB NZ licence and the same TAB NZ wallet. A punter who self-excludes from Betcha is self-excluded from TAB at the same time, and the deposit limits set inside one app apply inside the other.

The right pick for a punter whose main interest is football, cricket, basketball, or the big US leagues, and who wants the Same Game Multi builder sitting at the front of the screen rather than buried under a racing-led product.

RoyalistPlay (not licensed in New Zealand)

RoyalistPlay is an offshore brand operated by Novatrix SRL, a Costa Rica company with registration number 3-102-893958, and it states that it holds e-gaming licence No. 0000002 from the Tobique Gaming Commission. The Tobique licence gives no right to take bets from a person in New Zealand, and no New Zealand complaints route or harm-minimisation framework reaches the brand. The site carries a sports section and a casino section, with the usual mix of fixed-odds markets, live betting, and virtual sports, but the breadth of the menu is not a substitute for the lawful standing it lacks.

The situation for a Kiwi punter: the brand exists, the menu exists, but the New Zealand law treats the operator as in breach of section 74AAA from the moment a New Zealand punter places a bet, and the operator’s own licence does not put a New Zealand regulator, a New Zealand complaints body, or a New Zealand self-exclusion register in reach. As a result, it is not a recommended path.

Glorion (not licensed in New Zealand)

Glorion names no licence that applies in New Zealand. Support is available by live chat and email, and the site accepts customers aged 18 and over only. The sportsbook carries the usual pre-match and live menus, and the casino section sits alongside it.

The situation for a Kiwi punter: a brand that has not put itself inside any licensing frame a New Zealand punter might use to complain or to recover funds, and that is in breach of section 74AAA the moment it accepts a New Zealand bet.

Telbet (not licensed in New Zealand)

Telbet describes itself as a crypto casino and sportsbook. The site carries a welcome offer of 200% up to 1 BTC plus 50 free spins and a 5 USDT free bet on its Russian-language presentation. The sportsbook accepts cryptocurrency, and the cashier lists a narrower set of coins than a fiat bookmaker. The licence Telbet names does not apply in New Zealand.

The situation for a Kiwi punter: a brand whose selling point is the crypto cashier, not regulatory standing, and whose crypto rails do not provide a New Zealand harm-minimisation framework. It is best avoided.

Alawin (not licensed in New Zealand)

Alawin accepts customers aged 18 and over only. The site names no licence that applies in New Zealand, and the sportsbook carries a standard pre-match and live menu alongside a casino product. The 18+ floor is the only safety claim the operator makes that a New Zealand punter can read at face value; the rest of the operator’s book sits outside any New Zealand frame.

Thunderpick (not licensed in New Zealand)

Thunderpick is operated by Paloma Media B.V., a Curaçao company with company number 146988, under Curaçao licence OGL/2024/677/0722. The brand leans into crypto betting and esports, with the typical Counter-Strike, Dota 2 and League of Legends markets sitting next to a sportsbook. The licence is invalid in New Zealand.

The right read for a Kiwi punter who plays esports: the brand exists, the markets exist, and the New Zealand law treats the operator as in breach of section 74AAA the moment a New Zealand punter places a bet. The esports classification sits in the grey area research flagged earlier in this page.

22Bet (not licensed in New Zealand)

22Bet is one of a group of brands 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 the brand is 8048/JAZ. The sportsbook is one of the deepest on the offshore market, with a wide pre-match menu and a live product that covers most of the major leagues. The licence is invalid in New Zealand.

The right read for a Kiwi punter: a brand that competes on menu depth against a TAB NZ that has a much narrower racing product but a New Zealand licence behind every bet. The menu is wider; the regulatory frame is not there.

BigClash (not licensed in New Zealand)

BigClash offers pre-match and live sports betting across international and local leagues, with virtual sports and esports betting on FPS and MOBA titles sitting alongside. The site names a Curaçao licence (8048/JAZ) — the same group as 22Bet — which is invalid in New Zealand.

The situation for a Kiwi punter: a brand whose pitch is the breadth of the menu (sports, virtual, esports, casino), and whose regulatory frame is the same as the 22Bet group, with no New Zealand standing. It compares poorly to the licensed options.

Sportaza (not licensed in New Zealand)

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 two licence numbers are a clue to how the offshore licensing market works: the same brand can name different licences in different places, and neither one puts a New Zealand regulator in reach. The sportsbook carries a standard menu alongside a casino product.

The situation for a Kiwi punter: the brand exists, the licence citations exist, and none of them give the operator any standing in New Zealand. It does not meet the standards of a safe or lawful operator.

RoosterBet (not licensed in New Zealand)

Rooster.bet is operated by Novatrix SRL — the same Costa Rica company behind RoyalistPlay (registration number 3-102-893958) — under e-gaming licence No. 0000002 issued by the Tobique Gaming Commission. The site carries a sportsbook and a casino, and the licence is invalid in New Zealand.

The right read for a Kiwi punter: a brand that is one of two on this page run by the same operator group, and that sits in the same regulatory frame as RoyalistPlay — outside New Zealand.

The arithmetic of the odds, one more time

The margin calculation in the section above is the same arithmetic a punter uses to compare markets without trusting the headline price. A two-way market at $1.90 / $1.90 carries a 5.0% margin; the same market at $1.85 / $1.85 carries a 7.5% margin; a three-way football market at $2.40 / $3.20 / $2.90 carries a 6.9% margin. As a band, a typical two-way market sits between 5% and 7%, and the wider the band on the exotic markets (handicap lines, alternative totals, player props), the larger the gap the bookmaker keeps.

The punter who reads margin instead of price pays less over a season of bets, even when the visible prices look competitive. The punter who reads only the headline price pays the marketing word for the gift it is.

What “best” actually means in a monopoly market

The question this page opens with — “best bookies in New Zealand” — has two answers, and the answer that matters depends on what the punter is comparing. Compared on lawful standing, safer-gambling tools, regulator oversight, complaints route, and access to a New Zealand self-exclusion framework, TAB and Betcha stand alone: there is no other brand with any of those properties in New Zealand. Compared on menu depth, exotic market count, or crypto cashier convenience, the offshore brands a Kiwi punter meets on a search results page are wider — and they sit outside the lawful frame that gives TAB NZ its monopoly.

For a punter who wants to bet lawfully with a New Zealand-licensed bookmaker and the only available safer-gambling tools, the choice is between TAB and Betcha, and the pick is a brand pick, not a bookmaker pick. For a punter who is willing to step outside the lawful frame, the offshore brands offer a wider menu at the cost of every consumer protection New Zealand law provides. Neither answer is “best” in a vacuum; the best answer is the one that matches what the punter is willing to give up.

Frequently asked questions

Who may lawfully take online sports and racing bets in New Zealand?

TAB New Zealand is the only operator that may lawfully offer sports and racing bets to a person in New Zealand since section 74AAA of the Racing Industry Act 2020 took effect on 28 June 2025. The two online brands are TAB and Betcha, both run by TAB NZ under the same licence — they are not rival bookmakers. No other operator may offer these bets to a person in New Zealand, regardless of where that person is resident or incorporated.

What is a bookie in the New Zealand context?

A “bookie” in New Zealand usage is a bookmaker — the person or company that takes bets, sets the prices, and pays out the winnings. TAB NZ is the bookmaker for racing and sports in New Zealand. Offshore, the same word covers any brand taking bets, including the Curaçao-, Anjouan-, Tobique-, and Costa Rica-licensed brands a Kiwi punter meets on a search results page, none of which may lawfully take bets from a person in New Zealand.

What is a bookie agent?

A bookie agent is a person or business that takes bets on behalf of a bookmaker, usually for a commission. In New Zealand, TAB NZ runs its own retail and digital channels rather than using a network of independent agents in the traditional sense, so the agent role is narrower than in markets where bookmaking is licensed more widely. Offshore, an agent can mean an affiliate who refers a punter to a brand in return for a share of revenue, but the legal status of an affiliate in New Zealand is not established.

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

In decimal odds, the return on a winning single bet is the stake multiplied by the odds. A $10 stake at odds of $2.50 returns $25.00 — that is the stake plus the profit. For a combination bet, the odds of the legs multiply into one price: a multi with legs at $2.20, $1.80, $1.95 and $2.50 has a combined price of 2.20 × 1.80 × 1.95 × 2.50 = $19.31, so a $5 stake returns $96.55 if all four legs win.

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

The bookmaker’s margin is the share of every dollar bet on a market that the bookmaker keeps on average across all outcomes. It is read off the prices by converting each price to an implied probability (1 ÷ odds) and summing the implied probabilities across the market: a fair market sums to 1.00, a real market sums to something above 1.00, and the gap above 1.00 is the margin. A two-way market at $1.90 / $1.90 carries a 5.0% margin; a two-way market at $1.85 / $1.85 carries a 7.5% margin; a three-way football market at $2.40 / $3.20 / $2.90 carries about a 6.9% margin. As a band, a typical two-way market sits between 5% and 7%.

How can a punter compare two bookmakers offering the same market?

The right comparison is on margin, not on headline price. Two bookmakers offering the same head-to-head market at $1.90 are not offering the same deal if one of them carries a wider margin on the wider market — the price looks the same, the take behind the price is not. A punter who reads margin instead of price pays less over a season of bets, even when the visible prices look competitive.
