The giant Central Interceptor tunnel being bored underneath Auckland city has reached the half way mark!
The tunnel crosses underneath the Manukau Harbour from Mangere and is currently at May Road. It's end point is at Western Springs.
The project is the answer to decades of sewage spewing from old pipes every time it rains and will meet the needs of the city's growing population once it's finally up and running.
Watercare's Central Interceptor executive programme manger Shayne Cunis stops by to give us an update.
