Where gas comes from


Natural gas has been produced commercially
in New Zealand since 1959. Before then all gas sold in New Zealand came from coal. There are 6 main natural gas fields in New Zealand.

  • 3 are offshore: Pokohura, Maui and Kupe.
  • 3 are large onshore fields: Mangahewa, Turangi and Kapuni.

Another 12 smaller onshore fields also produce gas.

All gas produced in New Zealand comes from Taranaki.

Gas is also held in storage at Ahuroa. It can store up to about 18PJ of gas.

 

 

Two main sectors

The gas industry is divided into two main sectors: upstream and downstream. Our role and regulatory insight under the Gas Act encompasses the downstream sector.

Upstream sector

The upstream sector comprises gas exploration and production, both offshore and onshore.

This part of the sector is governed primarily through the Crown Minerals Act 1991, which is administered by the Ministry of Business, Innovation and Employment.

 

Downstream sector

Our role and regulatory insight under the Gas Act encompasses the downstream sector. This comprises:

  • processing facilities
  • transmission distribution
  • wholesale and consumer markets.

 

This diagram shows the structure of the industry, with the upstream sector at the top and the downstream sector.
