The North Island reticulated natural gas network is made up of gas transmission network and regional gas distribution networks.
The transmission network is the high-pressure gas backbone, supplying natural gas from Taranaki to large industrial customers throughout the North Island and distribution networks. The regional gas distribution networks in turn connect gas, at lower pressure, into individual homes and businesses.

Gas Transmission
First Gas operates the 2,200km First Gas transmission pipeline and the 300km Maui pipeline.
The gas transmission network was owned by Vector Gas until 2016 when ownership transferred to First Gas. First Gas is a subsidiary of First State Funds, part of the Commonwealth Bank of Australia’s group of companies.
The Maui pipeline was separately acquired by First Gas from an energy company consortium of Shell, Todd and OMV.

Gas Distribution
Vector Gas Network Map
Vector owns and operates the natural gas distribution network in the wider Auckland and Counties area. The Vector gas network extends north of Auckland to the Whangaparoa peninsula and as far south as Drury and Pukekohe.
To visualise the Vector gas network area, the easiest way is to look at the large Auckland ‘gap’ on the First Gas networks on the map below.
To find out whether you can get a Vector Gas connection from your property, the best place to start is the Vector Gas Connection Estimator page.
If you are looking for more detail on where the gas network runs, then sign up to the Before U Dig service (it’s free) and request utility network plans.
