Marton power upgrade

We upgraded our electricity network in Marton to increase the resilience of the network and meet the demand from the community as it grows.

The $10 million upgrade started in late May 2024 and was completed mid-2025.

A new switchroom was built at the Pukepapa Road substation and new cables are being undergrounded from the Arahina substation on Mill Street to the Pukepapa Road substation in Marton. 

What happened

• A new switchroom at the Pukepapa Road substation was built.
• A new 33kV underground cable was installed from the Arahina substation on Mill Road to the substation on Pukepapa Road.
• Two 11kV cables from the Arahina substation to the substation on Pukepapa Road were partially undergrounded.

The substations supply electricity to 7,000 customers, including those in the Bulls, Pukepapa, Arahina and Rata areas.
