The 2 networks behind that average
These are the Electricity Authority's figures, unaltered, for each network reporting region in West Coast. The headline above is their unweighted mean.
| Network region | Daily | Per kWh | Monthly | Low user |
|---|---|---|---|---|
| Buller (Buller Electricity)Buller Electricity | $3.31 | 36.18c | $241.48 | $173.55 |
| West Coast (Westpower)Westpower | $2.15 | 39.16c | $233.98 | $179.85 |
The Electricity Authority splits New Zealand into network reporting regions and publishes a figure for each. A user-facing region like West Coast is not one of them, which is why the headline above is a mean of these rows rather than a number the EA published. The lines company for each is the one you call in an outage — not your power company.

What is the average power bill in West Coast?
$238 a month for a standard user and $177 for a low user, on Electricity Authority figures for March 2026, GST inclusive. Those cover an average of 427 kWh a month for a standard user and 309 kWh for a low user. Your own bill scales with your own usage, so treat these as where the region sits rather than as a quote.
Have power prices in West Coast gone up?
The average standard-user bill has gone down 1.6% since January 2025, from $241 to $238 a month. That is the Electricity Authority's own series, which starts in January 2025 and is updated monthly.
Why does West Coast cost $238 a month?
Because of the daily charge and the unit rate together. In West Coast the average fixed charge is $2.73 a day for a standard user and the average unit rate is 37.67c per kWh. A low-user plan trades a smaller daily charge — $1.64 a day — for a higher unit rate of 42.39c, which is why which one suits you depends entirely on how much you use.
Is power more expensive in West Coast than elsewhere in New Zealand?
West Coast ranks 12th of 14 regions we publish, by average standard-user monthly bill. The dearest is Marlborough at $280 and the cheapest is Tasman at $228. Most of the difference between regions is lines charges, which are set by the network serving the address and are the same whichever power company bills you.
Why does West Coast have more than one set of prices?
Because West Coast is covered by 2 Electricity Authority network reporting regions (Buller (Buller Electricity), West Coast (Westpower)), and each has its own lines charges. The headline figures on this page are an unweighted average of those 2, which is our derivation rather than a published regional average, and the EA's per-network figures are shown beside it so you can see the spread.
West Coast is 12th of 14 regions by average monthly bill — Marlborough is dearest at $280 and Tasman cheapest at $228. See every region and town.
