The southern half of the tunnel from May Road, Mount Roskill to Māngere Wastewater Treatment Plant is operational, marking a major step forward for the project and the main tunnel boring machine Hiwa-i-te-Rangi completed her final breakthrough of the 16.2km, 4.5m internal diameter tunnel at Point Erin Reserve in Herne Bay.

Central Interceptor Project
Abergeldie, in a joint venture with Ghella, is delivering the Central Interceptor Project. This project will provide additional wastewater capacity to serve Auckland’s growing population and will reduce the frequency and volume of wastewater overflows, preserving the area’s beaches, estuaries, and waterways. The Central Interceptor Project involves the construction of a 16.2km long, 4.5m diameter underground tunnel that runs between 15m and 110m below ground from Grey Lynn and under the Manukau Harbour to the Māngere Wastewater Treatment Plant using tunnel boring machines.
