Power prices in Westport

As at May 2026, electricity in Westport averaged 47.24c per kWh including GST. For a household using 8,000 kWh a year on a low-user plan, paying on time and taking any prompt-payment discount, with controlled hot water, that works out to roughly $3,779 a year. That is 12.4% above the national average of 42.04c, making Westport the 9th most expensive of the 42 towns MBIE surveys.

Lines charges are the part of a power bill that changes most from town to town, because every area is served by a different network. In Westport the lines component is 18.21c per kWh — 39% of the total, against 40% nationally. The remaining 29.03c covers energy, metering and retailer costs, which vary far less by location.

Buller Electricity. Westport sits in the Buller (Buller Electricity) network reporting region, and Buller Electricity owns and maintains the poles and wires — so they are who you call in a power cut, not your power company. Your retailer is who you choose and who bills you; the lines company is fixed by where you live.

Yes. In February 2004 the Westport average was 21.20c per kWh; by May 2026 it was 47.24c — a rise of 123% over 22 years. Over the last twelve months alone it rose 3.5%.

Possibly. The MBIE figure is an average of publicly advertised tariffs across Westport, not a quote — what you pay depends on your usage, your meter and which company you are with. Switching retailer does not change the 18.21c lines component, but it does change the 29.03c that sits on top of it. Comparing the companies we work with is free and takes a couple of minutes.
