Our gas distribution network prices are increasing

From 1 October 2025, our gas charges will increase by an average of 7.96%. That's about 10c per day for residential customers.

We own and maintain the network of mains, service pipes, regulator stations and other infrastructure that delivers gas to customers in Hawke’s Bay, Horowhenua, Manawatū, Taranaki, and Wellington (including Hutt Valley and Porirua).

We continually invest in and maintain these assets to ensure we can continue to provide you with safe, reliable, resilient and future-ready gas.

Your gas bill

You pay your retailer (the company that sends your gas bill) for the gas energy you use and about 32% of what you pay comes to us as gas distribution charges. The remaining 68% of your bill is made up of your retailer's charges, GST, transmission and other charges. The overall impact of this year's changes on your gas bill will depend on how your retailer chooses to structure the prices they charge you.

We update our prices annually to reflect changes such as the number of customers in our service areas, and the costs of meeting your gas needs.

Our prices are regulated by the Commerce Commission, with the 2025 increase covering the impacts of inflation levels and depreciation costs.

The future of gas

We’re committed to a lower-carbon future for gas. That means continuing to provide reliable natural gas for our customers today, while we continue to work with industry to bring renewable gases like biomethane into our network in the future.

We’re focused on making sure households and businesses can keep enjoying the benefits of gas, now and in the future, as part of a more sustainable and resilient energy system. Find out more about the future of gas.
