Central Interceptor tunnel on track

Central Interceptor Tunnel

The Hiwi-i-te-Rangi tunnel boring machine (TBM) has broken through for the Central Interceptor tunnel project, marking the halfway point of its 14.7km journey to central Auckland, New Zealand.

The Central Interceptor tunnel will run from the Mangere Wastewater Treatment Plant to Grey Lynn and will be intersected by two link sewers.

The Watercare project, which is the largest wastewater infrastructure project in New Zealand, will clean up wet-weather overflows into waterways and the Waitemata Harbour.

Central Interceptor executive programme director Shayne Cunis said the breakthrough marks a significant milestone for the project.

“We’re on track to deliver this project in 2026 as planned despite everything that has been thrown at us—COVID-19 lockdowns, closed borders, global shipping delays and major weather events. But most importantly, the project is being delivered safely,” Cunis said.

“I want to pay tribute to our Ghella Abergeldie JV construction partners, as well staff from Jacobs, AECOM, Delve Underground, Watercare and our sub-contractors, who are all working so hard to deliver this project in the best way we can.

“This is our busiest year, with around 600 staff working on 16 sites. We’ve tunnelled under the Manukau Harbour, we’ve passed 110m under the Hillsborough Ridge, we’ll keep our heads down and keep going until we reach central Auckland.”
