How We Rate Online Casinos: Our Review Methodology
Every casino review published on Nzfisher is the result of a structured, hands-on evaluation process carried out by site owner and lead reviewer Mitchell Dreaver. Before a single word is written, Mitchell personally registers an account, makes real deposits, plays games, tests withdrawals, and contacts customer support — just like any New Zealand player would. There are no shortcuts, no copy-pasted information from casino press releases, and no paid placements disguised as honest opinions.
This page explains exactly how we assess online casinos for New Zealand players, what criteria we measure, how much weight each category carries, and how we arrive at our final scores. We believe you deserve full transparency about the process behind every recommendation on nzfisher.co.nz.
Our Step-by-Step Review Process
Mitchell follows a consistent, repeatable process for every casino reviewed on this site. The steps below are completed in order before any score is assigned.
- Step 1 — Registration: Mitchell creates a real player account using a New Zealand identity, checks the sign-up process for friction points, and verifies that the casino accepts NZD players.
- Step 2 — Licence Verification: Before going further, the casino's licence is confirmed directly on the issuing regulator's public database. Unverified licences result in automatic disqualification.
- Step 3 — Bonus Claiming: The welcome bonus and any available promotions are claimed to evaluate realistic wagering requirements, time limits, and eligible games.
- Step 4 — Game Testing: Mitchell plays a representative sample of slots, table games, and live dealer titles to assess software quality, loading speed, and fairness certifications.
- Step 5 — Deposits and Withdrawals: At least one real deposit and one withdrawal are completed using payment methods commonly available to New Zealand players, including POLi, Visa, and cryptocurrency where supported.
- Step 6 — Customer Support Testing: Support is contacted via live chat, email, or phone at different times of day to evaluate response speed, accuracy, and professionalism.
- Step 7 — Mobile Testing: The casino is accessed on a mobile device or tablet to evaluate the responsive experience, game availability, and navigation quality.
- Step 8 — Scoring and Writing: Each category is scored independently. The final rating is calculated from weighted category scores, and the review is written based solely on first-hand findings.

Understanding Our Rating Scale
All casinos are rated on a scale of 1 to 10. The final score is a weighted average of the six category scores listed above. Here is how to interpret the numbers:
- 9.0 – 10.0 — Outstanding: Among the very best options for NZ players. Excels across all categories with no significant weaknesses.
- 7.5 – 8.9 — Excellent: A strong all-round casino with minor limitations that do not meaningfully affect the player experience.
- 6.0 – 7.4 — Good: Worth considering for specific needs, but notable gaps exist in at least one or two areas.
- 4.0 – 5.9 — Average: Has some positive qualities but falls short in important areas. Approach with caution.
- Below 4.0 — Poor or Not Recommended: Significant issues with safety, fairness, or player experience. We do not recommend these casinos.
How Nzfisher Stays Independent and Unbiased
Maintaining editorial independence is central to everything we do at Nzfisher. Here is how we protect the integrity of our reviews:
- No paid reviews: Casino operators cannot pay to receive a higher score or a positive write-up. Revenue from affiliate commissions never influences ratings.
- Affiliate disclosure: We earn a commission if you sign up through our links. This relationship is disclosed openly and does not affect how casinos are scored.
- Negative reviews are published: If a casino fails our tests, that finding is published honestly. We do not suppress unfavourable results to protect commercial relationships.
- Regular re-evaluation: Casinos are revisited periodically to ensure scores reflect current standards. A casino that declines in quality will see its rating updated accordingly.
- One reviewer, consistent standards: Mitchell Dreaver personally oversees every review on this site, ensuring that the same methodology and standards are applied uniformly across all listings.
