Shayne Cunis: Watercare about to press go on tunnel boring machine

Watercare is about to press the “go button” for their giant tunnel boring machine, Hiwa-i-te-Rangi.
Hiwa-i-te-Rangi is about to dig her way under Auckland city to create Watercare’s $1.2 billion Central Interceptor wastewater tunnel.
It's an almost 15km underground tunnel that will stretch from Grey Lynn to the Mangere Wastewater Treatment Plant and will clean up 80% of Auckland’s waterways by preventing wet-weather sewage overflows.
Watercare Central Interceptor Executive Programme Director Shayne Cunis joined Kerre McIvor.
