Project milestone
Our main Tunnel Boring Machine Hiwa-i-te Rangi has arrived at our Haverstock Road site in Sandringham. She broke through the shaft wall 50-metres beneath Auckland. Domenica is now on her last drive, travelling 300-metres from Rawalpindi Reserve to Norgrove Avenue in Mt Albert. Then, link sewer B will be bored with just the surface works to complete over the next 12-18 months. At Keith Hay Park on the new sewer connector, we’ve established five of our seven sites for new manholes and our mini-Tunnel Boring Machine has completed three of her six drives.
