How We Rate

Our Review Methodology at Bayerboost

At Bayerboost, every casino review published on bayerboost.co.nz is the result of a thorough, hands-on evaluation process carried out by Liam Hargreaves. This page explains exactly how we assess online casinos for New Zealand players, what criteria we use, and why you can trust the scores we publish.

Our goal is simple: to give New Zealand players honest, accurate, and up-to-date information so they can choose a casino with confidence. We are not paid by operators to write positive reviews. Every rating reflects what we genuinely found during real testing.

Step-by-Step: How Liam Hargreaves Reviews a Casino

Liam Hargreaves personally tests every casino listed on Bayerboost before a review goes live. No site is published based on reputation alone or on information supplied by the operator. Here is the exact process followed for each review:

Step 1 – Licence Verification: Liam checks the casino's licensing credentials directly with the relevant regulatory authority. He confirms the licence is active, current, and covers New Zealand players.
Step 2 – Account Registration: A real account is created using genuine New Zealand details to experience the sign-up process exactly as a NZ player would.
Step 3 – Bonus Claiming: Welcome offers and ongoing promotions are claimed and their terms and conditions are read in full, including wagering requirements, time limits, and game restrictions.
Step 4 – Game Testing: A selection of slots, table games, and live dealer titles is played in both free and real-money modes to assess game quality, load times, and software variety.
Step 5 – Deposits and Withdrawals: Real deposits are made using popular NZ payment methods, including bank transfers, credit cards, and e-wallets. Withdrawal speeds and any associated fees are recorded.
Step 6 – Customer Support Testing: Liam contacts support via live chat and email, asking both simple and complex questions. Response times and the quality of answers are noted.
Step 7 – Mobile Testing: The casino is accessed on a mobile device to evaluate the quality of the mobile browser experience and any dedicated app performance.
Step 8 – Scoring and Writing: All findings are compiled into a final score using the weighted criteria below, and the full review is written based entirely on direct experience.

Our Rating Criteria and Weightings

Each casino is scored out of 10 across six key categories. A weighted average is then calculated to produce the final overall score. The table below shows each category and the weight it carries in the final rating.

Category	Weighting	What We Assess
Licensing & Safety	25%	Regulatory licence validity, SSL encryption, responsible gambling tools, fair play certifications
Bonuses & Promotions	20%	Welcome offer value, wagering requirements, bonus fairness, ongoing promotions for NZ players
Game Selection	20%	Number of titles, software provider quality, slots variety, table games, live dealer options
Payment Methods	15%	NZD support, available deposit and withdrawal options, processing times, transaction fees
Customer Support	10%	Live chat availability, response speed, helpfulness, email support quality
Mobile Experience	10%	Mobile browser performance, app availability, interface usability on smaller screens

Understanding Our Rating Scale

All casinos are scored on a scale of 1 to 10. Here is how to interpret those scores:

9.0 – 10: Outstanding. Among the very best options for NZ players.
7.5 – 8.9: Excellent. A strong, reliable casino with minor drawbacks.
6.0 – 7.4: Good. Solid overall but with noticeable areas for improvement.
4.0 – 5.9: Average. Acceptable but not recommended over higher-rated alternatives.
Below 4.0: Poor. Significant issues identified. We typically do not recommend these sites.

How Bayerboost Stays Unbiased

Independence is the foundation of everything we do at Bayerboost. Here is how we protect our editorial integrity:

No operator payments for reviews: Casinos cannot pay to receive a positive review or a higher score. Our ratings are never for sale.
Affiliate transparency: Bayerboost may earn a commission if you sign up through one of our links. This financial arrangement never influences the scores or written content of any review.
Regular re-evaluation: Casinos are re-reviewed periodically. If standards drop, scores are updated to reflect the current player experience.
NZ player focus: Every review is written specifically for New Zealand players in 2026. Factors like NZD banking, local payment support, and NZ-relevant terms are always prioritised.
