Frequently asked

What is the average power bill in Invercargill?

A typical 1-2 person household in Invercargill spends about $175 per month on electricity at the current 37.3c/kWh rate. A family of 3-4 pays around $259/month, and larger homes often exceed $411/month depending on heating choices.

Why is the power rate lower in Invercargill than the national average?

Invercargill sits 8% below the national average of 40.6c/kWh. Regional rates are driven by the local lines company's distribution charges and the retailer's generation mix, both of which MBIE tracks quarterly. Rural and remote South Island networks often pay more because their lines are longer per customer.

How much have rates risen in Invercargill?

Comparing the current 37.3c/kWh figure against Feb 2021 (27.9c/kWh), rates have risen 34% over the past five years. This is the MBIE QSDEP blended figure for a typical low-user household.

What is the best way to cut my power bill in Invercargill?

The biggest wins for Invercargill homes are the same as the rest of NZ: install a heat pump instead of plug-in heaters, put a timer on any heated towel rail, and switch to a night-rate plan for the hot water cylinder. The genuinely cold winters that push real-world heat pump efficiency down in this region mean heating is the single largest cost in winter.
