A super-sized tunnel that will reduce wastewater overflows into central Auckland waterways

Central Interceptor construction site soon to open in Mt Albert War Memorial Reserve

At the end of May the site opens in the Reserve’s lower carpark. Site set up is due to start in late May 2022, for about two years. We will be excavating a 32m deep shaft at this site and will launch our micro tunnel boring (mTBM) from here to our Norgrove Avenue site on Link Sewer B, an offshoot from the main CI tunnel. We will also use the Mt Albert site to inspect the condition of our main tunnel boring machine, Hiwa-i-te-rangi, as she passes by on her way to our Western Springs site. The first thing you will notice is our fencing which will go up as site preparations and clearing starts. We will be working with Auckland Transport to improve traffic calming devices in Wairere Avenue so that we can make moving past our site safer for cars and pedestrians.
