Editorial Policy & Review Methodology: How WinWinBar Rates Sites

This page explains how we research, test and rate the sites we recommend, and how we keep our reviews independent.

Our Review Methodology

We score every casino and bookmaker out of 5 against seven weighted criteria:

1. Licensing & safety — valid licence, encryption, fund handling.
2. Bonus value — real value after wagering, max bet and game weighting.
3. Payout speed — verified withdrawal times by method, in NZ business days.
4. Game / market range — quality and breadth of games or betting markets.
5. NZ payments — NZD support, POLi, cards, e-wallets, crypto.
6. Mobile experience — speed and usability on iOS and Android.
7. Support & fairness — responsive help and independently audited games.

Testing Process

Where possible we register real accounts, deposit in NZD, claim the welcome offer, play, and request a withdrawal — recording each step. We re-check operators regularly and stamp each page with a "last updated" date (this page: 2026-07-22).

Independence & Affiliate Disclosure

WinWinBar earns commission when readers sign up via some links. This is how we fund our work. It does not affect our ratings: rankings are editorial and merit-based, and we will lower or remove any site that treats players poorly, regardless of commercial relationship.

Accuracy & Corrections

We cite official sources (e.g. the DIA and IRD) for legal, tax and regulatory claims. If you spot an error, email [email protected] and we'll correct it promptly.

Responsible Gambling

Player welfare comes first. Every gambling page carries responsible-gambling guidance and the correct New Zealand support contacts. See our responsible gambling hub.
