Electricity pricing

We’re one part of your electricity bill

We own and maintain over 29,200km of local lines, cables, substations and other assets that deliver electricity to over 900,000 Kiwis across the North Island.

We bring the electricity to your door, and this part of the supply chain is called ‘distribution’.

The electricity bill you get from your retailer is made up of a number of charges:

Distribution
This covers our costs to invest in and maintain our network to ensure we provide safe and reliable electricity to your door now and in the future.
Transmission
This covers Transpower’s costs of getting electricity from the power stations where it’s generated to our network via the national grid. Transpower charges us, and we pass this on to you.
Generation, retail and other charges
This covers the costs of generating the electricity at the power station, your retailer’s costs, GST and levvies. This is also where you pay for the electricity that you use, as measured by your power meter reading.

We update our prices each year to ensure we can continue to meet electricity demand as the communities we serve continue to growth, and the way our customers use electricity changes.

Our new pricing is effective from 1 April each year.

The overall impact on your electricity bill will depend on things like how and when you use electricity and how your retailer chooses to pass our charges on to you.

Our prices from 1 April 2025

Our charges differ depending on the region you live in. This reflects things like the varying levels of investment needed, and the number of customers we serve in that area.

Our prices are regulated to ensure they’re fair

We’re regulated by the Commerce Commission to ensure we provide reliable electricity supply at a fair price to you.

As part of this, the Commerce Commission sets the amount of revenue we get from our customers in the form of charges once every five years.

The latest reset determines our revenue for 1 April 2025 – 31 March 2030.

The last time our revenue was reset was in 2019.

Since 2019 factors like inflation, interest rates and rising prices have all contributed to higher costs. Customer demand for electricity is also growing - as customers switch away from fossil fuels and towards EVs for instance. That means we need more investment to meet demand.

That’s why the Commerce Commission has allowed lines companies to increase their revenue in the latest reset. (The total revenue increase will be made gradually over the next five years, through our annual price changes).

You can find out more about the Commission’s decision on its website.

Increase in low-fixed user charges for residential customers

This year we’re continuing to phase out low-fixed charges in line with the removal of low-fixed charge regulations.

That means your low-fixed charge (if you’re on one) will go up, as we progressively bring it into line with standard daily fixed charges over the five years ending 2027.

Once complete, all of our residential customers will have the same daily fixed charge. That daily fixed charge rate depends on the region you live in. You can find your daily fixed charge rate in our pricing tables below.

To find out whether you are on a low-fixed charge you’ll need to contact your retailer (the company you pay your power bill to).
