Otahuhu–Whakamaru Aand B line reconductoring (Otara to Flatbush section)

Region Map
Otara to Flatbush section
Expected completion (or earlier) mid 202

We need to continually operate, maintain and develop New Zealand's transmission network - the National Grid - to ensure we meet the ongoing electricity needs of New Zealanders.

We are replacing the conductor (wire) on the Otara to Flatbush section of the Otahuhu–Whakamaru A&B transmission line in Auckland.  They are an important part of the grid and helps provide supply to the Auckland and Northland region.


Why we are doing it

The conductor on this section of line was commissioned in 1952, and after 68 years of service is now nearing the end of its economic life.  Corrosion from high levels of salt in the air have led to significant corrosion over its lifetime, and deterioration has reached a point where replacement in the near future is required in order to continue to provide a safe high voltage transmission service.

The work to replace the conductor is expected to commence in mid-2021 and be complete by 2023.  We do not expect any interruptions to your power, and the effects of the construction will be localised to those communities near the line
