The network behind that figure
Tasman sits on one network reporting region, so this row is the headline figure — nothing was averaged.
| Network region | Daily | Per kWh | Monthly | Low user |
|---|---|---|---|---|
| Tasman (Network Tasman)Network Tasman | $2.39 | 29.08c | $228.32 | $156.85 |
The Electricity Authority splits New Zealand into network reporting regions and publishes a figure for each. A user-facing region like Tasman 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.

Towns we track in Tasman
MBIE surveys 1 town in Tasman and publishes a price per kWh for each. That is a different survey from the figures above — one prices advertised tariffs for a model household, the other measures what regions actually pay — so they answer different questions.

What is the average power bill in Tasman?
$228 a month for a standard user and $157 for a low user, on Electricity Authority figures for March 2026, GST inclusive. Those cover an average of 554 kWh a month for a standard user and 342 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 Tasman gone up?
The average standard-user bill has gone down 3.8% since January 2025, from $237 to $228 a month. That is the Electricity Authority's own series, which starts in January 2025 and is updated monthly.
Why does Tasman cost $228 a month?
Because of the daily charge and the unit rate together. In Tasman the average fixed charge is $2.39 a day for a standard user and the average unit rate is 29.08c per kWh. A low-user plan trades a smaller daily charge — $1.60 a day — for a higher unit rate of 32.73c, which is why which one suits you depends entirely on how much you use.
Is power more expensive in Tasman than elsewhere in New Zealand?
Tasman ranks 14th 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.
