How Do We Rate Online Casinos?

Safety is the most heavily weighted part of every review. A site a player cannot reliably withdraw from fails here regardless of its games or promotions.

How we verify a licence

A licence only counts if it can be confirmed. We open the operator's footer, note the named regulator, and follow the licence number to that regulator's public register. A live entry confirms the company is valid and operational. A licence seal that is only an image, with no number and no link, is treated as no licence at all. Curaçao numbers in the old XXXX/JAZ format, such as 8048/JAZ, are no longer valid: those master licences expired between August 2024 and January 2025. Curaçao licensing now runs directly through the Curaçao Gaming Authority in the OGL/2XXX/NNNN/NNNN format. An operator still showing only an old-format number is flagged and kept off our lists.

We also confirm the licence covers players in New Zealand, with the local legal picture set out in our NZ gambling law guide.

Encryption and complaint record

We confirm current SSL/TLS encryption on the login and cashier pages, so account and payment data is transmitted in encrypted form. Reputation is judged on independent platforms like Trustpilot and Reddit, and we weigh the ratio of resolved to unresolved complaints and whether the operator answers disputes in public. A brand that settles complaints openly is more likely to process a routine withdrawal without friction.

A marketing claim of "secure" or "trusted" play carries no weight in our scoring. What counts is a licence number that resolves in a live register and a complaint record we can read. Where a licence cannot be confirmed, the operator does not reach our lists, whatever its welcome offer looks like.

Game range is a medium-weight factor: it shapes the experience but rarely decides whether winnings are paid, so it counts for less than licensing or payouts. We record the number of titles and the studios behind them, since a library built on providers such as Games Global, NetEnt, Playtech, Play'n GO, Pragmatic Play and Evolution signals content that has passed provider-level testing. A catalogue of around 3,000 games is the market standard, and libraries above 10,000 sit well beyond it. We check that titles are tested for fairness by independent laboratories such as eCOGRA, iTech Labs or GLI. These are testing labs and not regulators, and the two are not interchangeable. We also note whether games are available in demo mode before deposit, which lets a player see how a title behaves without funding an account. You can find the full review by type in our games library.

Payout reliability is one of the most heavily weighted criteria, second only to safety. A large game library means little if winnings are slow to reach a player's account.

We check which NZD methods each site supports and how they behave. Common NZD-friendly options include Account2Account bank transfer, which replaced POLi after POLi closed in 2023, alongside Paysafecard, Neosurf, NZD e-wallets, cryptocurrencies and, at some brands, Apple Pay and debit cards. Where POLi is still referenced, it was deposit-only and could not be used to cash out. A fuller breakdown sits in our guide to NZD payment methods.

Withdrawal speed is scored against the market: 1 to 3 working days is standard, under 24 hours is above standard, and past three days sits below it. We record the KYC threshold, meaning the deposit or withdrawal amount at which identity documents are requested, together with daily and monthly cash-out limits and any per-method fees.

Withdrawal delays almost always sit on the operator's side rather than the payment method: pending KYC, an unmet wagering requirement or manual approval, not the wallet itself. Cashing out to the same method used for the deposit avoids an extra anti-money-laundering check, while switching methods can trigger one.

Usability is a moderate factor. It affects comfort rather than whether a player is paid, but a site where a player cannot move around loses points. We check that navigation and game search work on desktop and mobile, that the cashier and live chat are reachable in a few steps, and which languages the site and support cover. Text and menus should stay legible without a player hunting for basic functions.

A bonus is scored on its terms, not its headline figure. We examine the wagering terms, since a 35x requirement on the bonus alone is easier to meet than 30x on bonus plus deposit. Then we check the maximum bet allowed during wagering, how much each game type contributes, which games or payment methods are excluded, and the rollover period. As a benchmark, a wagering requirement of 30x to 40x is standard and 20x or lower is player-friendly, while a seven-day rollover window is typical.

We work the terms through on real numbers. On a NZ$100 deposit with a 100% match and 40x wagering on the bonus, the NZ$100 bonus must be wagered NZ$4,000 before a withdrawal is possible. At a 10% table-game contribution, table play counts for a tenth of each bet toward that total. Reload offers, cashback and VIP tiers are recorded but weigh less than the fairness of the core welcome terms. Live offers and their terms are tracked in our bonuses guide.

Most Kiwi players play at online casinos on a smartphone, so mobile performance carries real weight in our scoring rather than sitting at the bottom of the list. We open the site in a mobile browser to confirm the main desktop features remain, then check any native apps, whether an Android APK and an iOS App Store app, for the same access to logins, games, payments and bonuses as the full site. Load speed, touch navigation and a working cashier on a small screen all feed into the score. The brands with the strongest apps appear in our mobile casinos list. 

The figures we collect only mean something when compared to a market baseline. The table below shows where a measurement sits relative to the wider New Zealand market. A site can rate above standard on some measures and below on others, and each review states which. 

How the Numbers Rate Against the Market

Measure	Below market	Standard	Above market
Total games	under 3,000	3,000–5,000	over 5,000
Average slot RTP	under 96%	96%	97% and above
Wagering requirement	above 40x	30x–40x	25x or lower
Withdrawal speed	over 3 days	1–3 working days	under 24 hours
KYC verification	over 3 days	up to 3 days	within 1 day
NZD payment options	under 10, no local methods	around 10 fiat and crypto	over 10 with local NZD options

We don't sell placements. A commercial relationship with an operator does not raise its score, and a position on our lists cannot be bought. We earn commissions from some operator links at no extra cost to players, and those arrangements never change a rating or a ranking.

Each casino review reports limitations next to strengths, so a slow payout, a high wagering requirement or a limited list of withdrawal methods is stated plainly. Where a number cannot be confirmed from the operator's own terms, we show a dash rather than estimate it. Casinos are re-checked when ownership, licence status or terms change, so a rating reflects the operator as it stands now rather than at first review.

Gambling should stay within the limits a player sets before they start. Anyone who feels their gambling is becoming a problem is pointed to NZ support services, such as the Gambling Helpline and the Problem Gambling Foundation of New Zealand, rather than to a casino's own support desk.
