Mill Road – new connection from Manukau to Drury South

Mill Road will provide a safer, more reliable and accessible transport corridor to support residential and employment growth in south Auckland.

Part of Auckland's Supporting Growth Programme, Mill Road is an additional route from Manukau to Drury. It will provide better access for the 120,000-plus people who will make Auckland’s southern suburbs their home during the next three decades.

The new 21.5km corridor, running parallel to State Highway 1, will be built before the end of this decade, providing residents with a safer way to move between the communities of Manukau, Manurewa, Papakura and Drury. The new four-lane corridor with separated walking and cycling facilities will ensure better access to employment opportunities and provide residents with more reliable public transport services.

The NZ Upgrade Programme provides an estimated $1.354 billion to complete all stages of Mill Road. Work will begin now on property purchase and the planning and design for the alternative route. Construction is expected to start late 2022.

The development upgrades the existing two-lane sections of Mill Road to four lanes, connecting through to the new sections of the corridor being built across greenfield sites. These new sections connect to Drury through Opaheke and Papakura. The project includes an interchange overbridge at Drury to connect safely with SH1.

The new corridor will build greater resilience into Auckland’s state highway network by helping to manage the high demand on SH1. Mill Road will provide a safe, easy-to-use alternative route for local trips, helping to reduce traffic volumes on SH1 and, keep inter-regional travel and freight moving to support economic growth.
