A number of safety improvements are proposed for the Dairy Flat Highway as part of Auckland Transport’s road safety network review.
Public feedback closed Sunday 1 July 2018.
Project status: Investigation
Project zone: North
As part of our road safety network review, Auckland Transport has identified a number of safety risks along the the Dairy Flat Highway.
The Dairy Flat Highway is a former NZ Transport Agency (NZTA) State Highway, and is ranked within the top one per cent of roads recommend by NZTA for investment due to the high-risk intersections and roadside hazards.
- Safer journeys for people driving around Dairy Flat Highway.
- Potential for new safety measures such as flexible road safety barriers, wider centrelines, slow vehicle lanes, rumble strips and intersection upgrades.
- Safe speeds, including lower speed limits.
- Reducing the speed limit and traffic calming will create a more appropriate village feel, especially around the Kahikatea Road intersection.
- June-July 2018 – stakeholder engagement on Dairy Flat Highway safety improvements.
- December 2018 – public information on the Dairy Flat Highway safety improvements
- 2019/20 – construction starts on safety improvements
The Dairy Flat Highway sits within the top one per cent of roads recommended by NZTA for investment because of the speeds, dangerous intersections and roadside hazards.
The former State Highway has also had a number fatalities and serious crashes.
Between 2008 and 2017 there have been nine deaths and 55 serious injuries.
The North Shore’s population is expected to grow by 17 per cent over the next 10 years, with 6,000 more homes to be built around Silverdale and Dairy Flat. With vehicle numbers set to increase over the next decade, better and safer roads are required.
As part of Auckland Transports road safety review along Dairy Flat Highway, Auckland Transport asked the community for feedback to identify any safety concerns and potential safety improvements. We consulted on this proposal from Friday 8 June to Sunday 1 July 2018, and received 391 submissions.

Following consultation in June/July 2018, Auckland Transport has identified a number of safety improvements to improve the driving conditions and safety along the Dairy Flat Highway. The majority of the work is expected to take place from 2019 onwards, with some of the projects to commence from 2020.
