Last updated: June 2026 — Liam Hartley, Montessori Vietnam
At Montessori Vietnam, every casino review published on montessori-vietnam.com is the result of a thorough, hands-on evaluation conducted by Liam Hartley. Our mission is simple: to give New Zealand players honest, accurate, and genuinely useful information before they deposit a single dollar. We do not accept payment from operators in exchange for favourable reviews, and we never publish a rating without completing our full testing process first.
This page explains exactly how we assess each casino, what criteria matter most to us, and how our final scores are calculated. We believe transparency in our methodology is just as important as transparency in our reviews themselves.
Before anything else, Liam checks whether the casino holds a valid licence from a recognised regulatory authority. Sites without legitimate licensing are rejected immediately and will never appear in our recommendations. This non-negotiable first step protects our readers from unsafe platforms.
Liam personally creates a real player account on every site under review. He completes the full registration process, submits KYC documents, and records how smooth, transparent, and fast the verification process is. This gives us a genuine first-person experience of what new NZ players can expect.
Real money is deposited and withdrawn using payment methods commonly available to New Zealand players, including credit cards, e-wallets, and bank transfers where applicable. We track processing times, fee structures, and whether withdrawal limits are clearly communicated. No review is finalised until at least one withdrawal has been processed and confirmed.
Liam plays a representative sample of games across multiple categories, including slots, table games, and live dealer options. He evaluates game loading speed, software quality, fairness indicators, and the overall playing experience on both desktop and mobile devices.
Welcome bonuses and ongoing promotions are claimed and tested under real conditions. We read every line of the terms and conditions and assess whether wagering requirements, time limits, and game restrictions are fair and clearly disclosed to players.
Liam contacts each casino's support team through all available channels, including live chat, email, and phone where offered. He submits both simple and complex queries to evaluate response times, the quality of answers, and overall helpfulness.
Every casino is accessed on a mobile device to assess app or browser performance, game availability, navigation ease, and whether the full suite of banking and support features is accessible on smaller screens.
Each casino receives a final score out of 10. This score is calculated by combining weighted scores across six core categories, as outlined in the table below.
| Rating Category | Weighting | What We Assess |
|---|---|---|
| Licensing and Safety | 25% | Valid licence, SSL encryption, responsible gambling tools, fair play certification |
| Bonuses and Promotions | 20% | Offer value, wagering requirements, terms clarity, ongoing promotions for NZ players |
| Game Selection | 20% | Volume and variety of titles, software providers, RTP transparency, live casino quality |
| Payment Methods | 15% | NZD support, deposit and withdrawal options, processing speeds, fee transparency |
| Customer Support | 10% | Availability, response times, quality of assistance, channel variety |
| Mobile Experience | 10% | App or mobile browser performance, game availability, ease of navigation |
