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.
We are seeking your views on our preferred solution for reconductoring (replacing the transmission lines). Please email your written feedback to [email protected] by 5pm, Friday 18 July 2025.
Following the consultation period, we will consider feedback received in submissions. Based on the information received, we will 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.
