Downer, as part of Link Alliance, is delivering the new and redeveloped stations, tunnels and systems for Auckland’s City Rail Link projects, the largest transport infrastructure projects ever undertaken in New Zealand.

Downer’s involvement in Link Alliance follows its involvement in the earlier cut and cover tunnels and refurbishment of the Central Post Office. 

The City Rail Link is a 3.45 kilometre twin-tunnel underground rail link, up to 42 metres below the city centre. This is transforming the downtown Britomart Transport Centre into a two-way through-station, that better connects the Auckland rail network. The City Rail Link is due for completion by November 2025.
