Ōtāhuhu–Whakamaru A and B Lines reconductoring project consultation

The Ōtāhuhu–Whakamaru A and B lines (OTA-WKM A&B) are an important part of the upper North Island transmission network, connecting the Auckland network to generation from the south. We have identified that 31 km of each circuit, from Flatbush to Hūnua, needs replacing due to internal corrosion.

Consultation on this project has now closed and we are currently considering feedback received in submissions. We plan to publish a summary on our project page shortly. 

Following consultation, we plan to prepare an application to the Commerce Commission to seek approval to increase our base capex funding baseline for RCP4 to account for this work. Our intent at this stage is to make this application in October 2025.  

Consultation documents:

Our consultation documentation includes an overview document, and two appendices (B and C).

Consultation responses:

We intend to publish all submissions and further information on our website. 

If you have questions during the consultation period, please email: [email protected].  

Ngā mihi in advance for your assistance with this project.
