Last October TBM Dame Whina Cooper successfully completed the first City Rail Link tunnel and is now currently being reassembled at Mt Eden. All parts of the TBM, the cutterhead, front shield, middle shield and the tailskin, have been brought back to the Mt Eden tunnel portal. Welding works carried out by Link Alliance have begun and assembly should take a fortnight.

The TBM gantries are still slowly moving back through the tunnel to Mt Eden Station, where they will be realigned with the new tunnel entrance and connected to the front shield for the second drive.  

Boring of the second and final 1.6km TBM tunnel to Aotea Station again  is now scheduled to begin in May.  For further information and to follow the progress of the tunnel please click here and nz/15 for the tunnelbuilder archive and also visit https://www.cityraillink.co.nz/. 09/22.
