The project is part of a longer-term transport network being investigated and delivered to support growth in south Auckland. Auckland is growing, fast and the south is the largest future urban growth area. About 1.7 million people live in Auckland and over the next 30 years this could grow to reach 2.4 million.
Over the next 30 years, southern growth areas such as Pukekohe, Drury, Paerata, and Takanini, could provide up to 40,000 new homes, as well as new jobs. These improvements will provide better choices for existing communities and the extra 120,000 people who will make the area home.
Investing in public transport, walking and cycling facilities as well as investigating options for prioritising multiple occupancy vehicles plays an important part in building a strategic transport network which meets the needs of the people who live, work and travel in the area.
Through the New Zealand Upgrade Programme (NZUP), Waka Kotahi and KiwiRail will begin construction of $2.395 billion of transport improvements for south Auckland within the next three years, including SH1 between Papakura and Drury South, Mill Road, rail electrification to Pukekohe and new rail stations for Drury.
NZUP for Auckland delivers on the Government’s commitment to support the transformation of Auckland’s transport system.
SH1 Papakura to Drury South was announced by the Government in January 2020 to be part of the upgrade programme to facilitate the growth and economic prosperity of the area. This project’s improvements will support the growth of communities by improving access along and across the motorway, enhancing local connectivity and resilience.
Papakura to Drury South highlights
- 10km of new traffic lanes and bus shoulder lanes in each direction
- 9km of new walking and cycling paths
- 100% of highway stormwater treated
- 20%* increase in people moving through at morning peak
- 14%* increase in freight moving through at morning peak
*Based on traffic modelling for year 2046.

Improvements to SH1 from Drury South to Bombay is likely to be built in the longer term, in line with the projections for longer term population growth and the release of land in new growth areas. At this time, we will only be seeking statutory approvals for route protection for this section of the motorway.

What is planned for the project?
Travel on State Highway 1 (SH1) between South Auckland and the city centre will be safer and more reliable for commuters with a range of improvements between Papakura and Drury South to support significant residential and employment growth in South Auckland.
The project will provide better travel options, with new walking and cycling facilities, improved highway access and safety, future-proofing for bus lanes, and allowing for electrification and additional rail capacity.
This project includes:
- a 9km walking and cycling pathway alongside the northbound side, linking in with the city-wide network being continually developed
- wide shoulders to future-proof for public transport services
- an additional third lane in each direction along 10 kms of the existing highway between Papakura and a new interchange at Drury South, which will also connect in with the new Mill Road corridor. This additional third lane is being investigated for dedicated use by high occupancy vehicles and/or freight.
- interchange improvements at Papakura (including a new southbound on-ramp) and Drury (to allow for electrification of the railway from Papakura to Pukekohe and additional rail line/s)
- Improved local road connections and community access along and across the motorway.
The Papakura to Drury South project will be consented and constructed in phases over the next five years.
Stage 1A for works within the existing motorway boundaries between Papakura and the BP Drury motorway service centre has been consented and construction is expected to start in early 2021.
Other stages will be lodged and consented progressively in 2021/22 subject to confirmation of the final design.
Stage 3 from Drury South to Bombay is not part of the NZ Upgrade Programme. Route protection for the future upgrade of this section will be progressed, although there is no timeframe for implementation. Construction will occur when warranted by future growth.
