Northern busway – Power cable repair works

Last updated: 24 May 2024

What we’re doing 

Transpower is undertaking urgent repair work on an underground power cable. This work will impact on the Northern busway. There are two sections of the cable (the Hobson St to Wairau Rd 220kV cable) that need to be repaired. 

Northpower will be conducting the work on behalf of Transpower. 

We are coordinating with Auckland Transport and Auckland System Management to plan this project work to be as least disruptive as possible to the public.


Why we’re doing it 

The underground power cable is damaged. If we don’t repair the cable, it could stop working which would result in power cuts. Fixing the cable now means that further disruption is avoided. 


How it affects you

We wish to advise motorists and Auckland residents that the Onewa Road southbound onramp will close from 8pm until 7am, on Friday, Saturday and Sunday nights 31/05/24 – 03/06/24 (King’s Birthday weekend). 

This road closure will allow us to do maintenance repair work on its underground cables.  

A diversion will be in place via the Onewa Road northbound onramp and Northcote Road.  

We apologise for the inconvenience.
