Te kaupapa – about the project

South Auckland is growing fast, with an additional 120,000 people expected to make it their home during the next 30 years.

NZ Transport Agency Waka Kotahi (NZTA) Mana Whenua, Auckland Transport and KiwiRail are working together to plan and deliver road and rail improvements in South Auckland to support this future growth.

In Drury, we are getting on with preparation to upgrade part of State Highway 22 (SH22).

The project will provide access to the planned Ngākōroa Railway Station, as well as new housing developments.

The SH22 upgrade project is located on 2km section between the intersections of SH22/Mercer Street and SH22/Jesmond Road. The improvements will provide access to the planned Drury West housing development area and Ngākōroa Railway Station.

The Government has approved pre-implementation funding to allow design work to progress.

Other projects in South Auckland include the Waihoehoe Road upgrade, SH1 Papakura to Drury improvements, three new rail stations between Papakura and Pukekohe, rail electrification between Papakura and Pukekohe, and the Wiri to Quay Park rail project, which includes building a third main line between Westfield and Wiri junctions.
