The Government decided in June 2021 not to proceed with the full Mill Road corridor and asked Waka Kotahi to develop a business case to upgrade the Mill Road north area (part of Redoubt Road, Hollyford Drive, Aspiring Avenue, Murphys Road, Mill Road and Cosgrave Road)*, and investment in Drury local transport upgrades. The aims are to improve safety, improve walking, cycling and public transport connections and support additional housing.

The Government made this decision to meet climate change and housing objectives, as well as manage costs and debt responsibly following COVID-19.

Savings from these changes to Mill Road is allowing investment in transport upgrades to provide access to planned new housing development and rail stations in Drury in a way that supports the Government’s decarbonisation goals, makes streets safer, and provides more reliable connections.

Waka Kotahi has developed options and is continuing to work on the business case for the rescoped Mill Road and Drury transport improvements. The rescoped business case will be presented for ministers’ approval in mid-2023. This includes investigating improvements to Murphys Road (including realigning the Murphys/Redoubt Road intersection).

The previous proposals for the full Mill Road corridor, which is not proceeding through the New Zealand Upgrade Programme (NZUP), remains part of the South Auckland strategic transport network endorsed as part of the Auckland Transport Alignment project (ATAP). Long term route protection remains a consideration but would be dependent on funding availability through sources other than NZUP.
