As part of the project, Mott MacDonald will lead the design of the stations, as well as the mechanical and electrical systems.

Work under the CRL upgrade project includes the construction of two 3.4km-long twin tunnels. It aims to extend the existing underground rail line with additional stations in the city station.

"CRL is the most significant improvement to Auckland’s transport network since the opening of the Auckland Harbour Bridge."

The CRL enhancements will also provide passengers with access to additional, faster trains, which will run more frequently to an increased number of destinations.

Mott MacDonald project director Peter Taylor said: "CRL is the most significant improvement to Auckland’s transport network since the opening of the Auckland Harbour Bridge.

"It will help shape the city’s future, linking to the existing rail system to support economic and population growth, helping Auckland become a globally competitive city.

"Mott MacDonald first began working on the CRL in February 2012, when the team led station designs and produced concept designs. Where possible, the project is below city streets to reduce the need for effects for property owners and city heritage buildings."
