How We Rate Casinos
At studiokoi.co.nz, we evaluate online casinos using a comprehensive methodology to help New Zealand players find the best platforms for their gaming preferences. Our ratings are independent, evidence-based, and updated regularly to reflect industry standards and player feedback.
1. Licensing & Regulation
We prioritise casinos holding valid licences from recognised regulatory authorities. We assess:
- MGA (Malta Gaming Authority) licences
- UKGC (UK Gambling Commission) licences
- Curaçao eGaming licences
- Local New Zealand gaming approvals and compliance with NZ gaming laws
Unlicensed or poorly regulated casinos receive significantly lower ratings, as player protection is paramount.
2. Game Selection & Software Providers
We evaluate the breadth and quality of gaming offerings, including:
- Pokies (slots) from reputable providers like NetEnt, Pragmatic Play, and Microgaming
- Live casino options (live roulette, blackjack, baccarat)
- Table games and specialty games
- Game variety, RTP rates, and exclusivity of titles
A diverse library from established software developers enhances player experience and trustworthiness.
3. Bonus Terms & Wagering Requirements
We analyse all promotional offers with careful attention to:
- Transparency of Terms & Conditions
- Wagering requirements (rollover multiples)
- Maximum cashout limits on bonuses
- Fairness of playthrough conditions and game eligibility
- Bonus validity periods
Unrealistic wagering requirements or hidden restrictions result in lower ratings.
4. Payment Methods & Withdrawal Speed
We assess the accessibility and efficiency of financial transactions:
- Accepted payment methods (credit/debit cards, e-wallets, bank transfers, cryptocurrency)
- Average withdrawal processing times
- Availability of NZD currency options
- Transaction fees and minimum/maximum limits
- Security of payment gateways
Fast, reliable withdrawals and multiple payment options are essential for player satisfaction.
5. Customer Support
We evaluate the quality and availability of customer service:
- 24/7 live chat availability
- Email support responsiveness (typically within 24 hours)
- Phone support availability
- Knowledge and helpfulness of support staff
- Response times during peak hours
Reliable, professional support is crucial for resolving issues quickly.
6. Mobile Experience
We assess the quality of gaming on mobile devices:
- Responsive web design and mobile optimisation
- Availability of dedicated iOS and Android apps
- App performance, stability, and user interface
- Game compatibility and graphics quality on smartphones/tablets
- Ease of navigation and account management on mobile
With most NZ players accessing casinos on mobile, excellent mobile experience is non-negotiable.
7. Responsible Gaming Tools
We examine commitment to player protection through:
- Deposit limits (daily, weekly, monthly)
- Loss limits and session time limits
- Self-exclusion options (temporary and permanent)
- Cooling-off periods
- Links to problem gambling resources (Gambling Commission, Gambler's Anonymous)
- Account reality checks and mandatory breaks
Strong responsible gaming features are essential for safe, sustainable gaming.
8. Our Rating Scale
We rate casinos on a scale of 1 to 10, with the following breakdown:
- 9–10: Excellent – Highly recommended. Strong across all criteria with exceptional player protection and gaming experience.
- 7–8: Very Good – Recommended. Above-average in most areas; minor weaknesses in one or two categories.
- 5–6: Average – Acceptable, but with notable limitations. May suit some players; caution advised.
- 3–4: Poor – Not recommended. Significant concerns regarding licensing, fairness, or player protection.
- 1–2: Unacceptable – Not reviewed or actively discouraged due to regulatory issues, scam reports, or severe deficiencies.
Our ratings are updated quarterly and reflect the latest industry developments, regulatory changes, and player feedback. We encourage players to use our methodology as a framework for their own due diligence when selecting an online casino.
