Project Scope

Port Marsden Highway to Te Hana (where the route will meet the Auckland motorway network) is the second stage of the Whangarei to Te Hana project.

The upgrade will be planned and delivered in stages:

  • Port Marsden Highway to Waipu
  • Brynderwyn Hills bypass
  • Brynderwyn Hills to Te Hana


This section of State Highway 1 (SH1) is a long-term programme of investment that will improve safety, reliability and resilience of the network. The improvements will reduce the cost of travel for the freight industry, and improve the ability of Northland to attract investment and tourism.

After a re-evaluation undertaken by Waka Kotahi New Zealand Transport Agency (NZTA) in October 2018,  a recommended programme of work for the Port Marsden Highway to Te Hana section was announced:

  • safety improvements,
  • upgrades to alternative routes to SH1 between Port Marsden Highway and Te Hana, and
  • route protection for a bypass of Brynderwyn Hills


Construction timing will be based on prioritisation of projects nationally.

Originally, two options were shortlisted for the Bynderwyn Hills Bypass. They were approximately 15-20 kilometres long and avoid areas of significant cultural and environmental value. The total estimated cost of the section was $500 million - $800 million.



Project History
