Overview
This is one of the largest transmission projects to be undertaken in New Zealand since 1960. It is vitally important to meet the growing electricity demand in the upper North Island.
There are three major components: an overhead transmission line, substations and underground cables. The 186 km, 400 kV capable overhead transmission line runs from a new substation at Whakamaru to a new switching station in South Auckland. Four underground 220 kV cable circuits will run from this substation - two circuits to a new substation at the existing Pakuranga site and, at a later date, two circuits to Otahuhu substation.
