How We Rate

Our Casino Review Methodology at Energyzone

Every casino review published on Energyzone (energyzone.co.nz) follows a structured, hands-on evaluation process developed and carried out by Daniel Hargreaves. This page explains exactly how we assess online casinos for New Zealand players in 2026, what criteria matter most, and why you can trust our ratings to be honest and independent.

We do not accept payment from casinos in exchange for favourable reviews. Our scores reflect real testing, genuine player experience, and objective analysis — nothing more, nothing less.

Step-by-Step: How Daniel Hargreaves Reviews Each Casino

Before any score is published, Daniel personally works through each casino using the following process:

Step 1 — Registration: Daniel creates a real account using a New Zealand identity and address to replicate the exact signup experience a local player would have.
Step 2 — Licence Verification: Licensing documents and regulatory credentials are checked directly against the issuing authority's public register.
Step 3 — Deposit and Withdrawal Testing: Real money is deposited and a withdrawal is requested to test processing times, fees, and NZD support firsthand.
Step 4 — Bonus Claiming: Welcome offers and ongoing promotions are claimed and the terms are read in full, including wagering requirements, game restrictions, and cashout limits.
Step 5 — Game Testing: A sample of slots, table games, and live dealer titles are played in both real-money and demo modes where available.
Step 6 — Support Contact: The customer support team is contacted via live chat, email, or phone to assess response times, helpfulness, and availability.
Step 7 — Mobile Review: The casino is accessed on a mobile device to evaluate browser performance, app quality, and ease of navigation on a smaller screen.
Step 8 — Scoring and Write-Up: Each criterion is scored individually and combined into a final rating. The written review is completed by Daniel with no input from the casino being reviewed.

Understanding Our Rating Scale

Every casino on Energyzone receives a score out of 10. Here is how to interpret each range:

9.0 – 10.0 — Outstanding: Exceptional across all categories. A top-tier choice for New Zealand players.
7.5 – 8.9 — Very Good: Strong performance with only minor weaknesses. Recommended with confidence.
6.0 – 7.4 — Good: Solid option but with notable areas for improvement. Worth considering depending on priorities.
4.0 – 5.9 — Below Average: Significant shortcomings that affect the overall player experience.
Below 4.0 — Poor: Serious concerns around safety, fairness, or player treatment. Not recommended.

How Energyzone Stays Unbiased

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

No paid placements: Casinos cannot pay to receive a higher score or a featured position in our rankings. Placement is determined by score alone.
Affiliate transparency: Energyzone may earn a commission if you sign up through one of our links. This commercial relationship never influences the rating a casino receives.
Scores can drop: We revisit and update reviews regularly. If a casino's service declines, its score will be revised downward and the review updated to reflect current conditions.
Negative findings are published: If Daniel identifies problems during testing — slow withdrawals, misleading bonus terms, poor support — those findings are included in the review without softening.
No operator input: Casinos do not see or approve review content before publication. The opinion expressed is Daniel's alone.
