Precinct Properties is developing a new business, entertainment and retail destination to be known as Commercial Bay.
It's on the site of the former Downtown Shopping Centre, which opened in 1975 and was demolished in 2016.
The site is adjacent to the Britomart Transport Centre in Lower Queen Street.
An agreement was reached with Precinct Properties for the CRL tunnels to be built below and through their site as part of the redevelopment. The land was already designated for rail purposes and owned by KiwiRail.
So the twin-tunnels will emerge from Britomart Transport Centre (the former Chief Post Office), under Lower Queen Street and through the Commercial Bay development, avoiding the existing Zurich building, before proceeding up Albert Street.
The Precinct development is by Fletcher Construction and is geographically separate from the City Rail Link contracted works. The two shallow curved tunnels will be underneath the 39-storey commercial office tower which is a major part of the Commercial Bay development.
