Selectra’s Opinion on Mercury Energy
Mercury combines renewable generation with retail services and it’s known for strong renewable credentials and a wide product set (energy, broadband, mobile). Pros include reliable green generation and scale, cons are that large retailers’ tariffs can be mid-market and some customers prefer specialised prepay or low-use plans offered by niche suppliers.
Review sites like Trustpilot can provide useful insights, but they are often dominated by customers who had a negative experience. As a result, the overall rating may not accurately reflect the typical experience for most customers, but rather the opinions of a vocal minority. For the most accurate picture, it’s best to consider both positive and negative reviews together.

How Do I Switch to Mercury Energy?
With many electricity providers operating across New Zealand, switching to Mercury Energy — or any other power company — is a simple process that can help you find a better deal or improve your service experience. Whether you’re after lower rates, renewable options, or better customer support, the steps are straightforward.
Here’s how to make the switch:
- Gather Your Information: Find a recent electricity bill to note your ICP number (Installation Control Point) and your average energy usage. This information ensures accurate plan comparisons.
- Compare Plans and Rates: Review electricity plans from Mercury Energy and other New Zealand providers. Check daily charges, unit rates (¢/kWh), contract lengths, and any exit fees to see which option fits your household best.
- Start Your Switch: Once you’ve found the right plan, begin your switch on Mercury Energy’s website or by calling their customer service team. They’ll handle all contact with your previous provider.
- Provide a Final Meter Reading: On or before your switch date, submit your meter reading to finalise the transfer. This ensures an accurate final bill from your old provider.
Switching electricity providers in New Zealand is quick, easy, and seamless — your power supply won’t be interrupted during the process.
