The video shows the main launch shaft being constructed at the Māngere pump station where Tunnel Boring Machine (TBM) Hiwa-i–te-Rangi will begin its 14.7 km journey later this year.
The Central Interceptor will run underground from Western Springs, near the Auckland Zoo, to the Māngere Wastewater Treatment Plant.
The Watercare project is being delivered by the Ghella Abergeldie Joint Venture (GAJV) and will comprise nearly 20 km of tunnels, more than 17 shafts, a major pump station and significant wastewater management and network infrastructure works.
The project will result in cleaner waterways for central Auckland and is scheduled for completion in 2025.
