The Northland Corridor is a 100 km stretch of highway connecting Auckland to Northland. Made up of 3 Roads of National Significance (RoNS), it will support economic growth and productivity, reduce congestion, improve safety, support housing development, and provide a more resilient roading network.
Connecting to Ara Tūhono - Pūhoi to Warkworth in the south, the Northland Corridor is made up of 3 Roads of National Significance (RoNS): Warkworth to Te Hana, Te Hana to Port Marsden Highway and Port Marsden Highway to Whangārei.
Stretching from Warkworth to Whangārei, the road will address the critical resilience and safety issues facing the current road. Northland has one of the worst safety records in the country and SH1 over the Brynderwyn Hills was closed in both directions last year for 36 days and closed southbound only for 37 days – totalling 73 days.
The new road will unlock economic growth and productivity by moving people and freight efficiently, quickly, and safely across the region, support housing development and provide more resilience during extreme weather events.
Ara Tūhono - Warkworth to Te Hana is designated and consented with property purchases underway and we’re planning to commence construction of this section by the end of 2026. We’re also assessing previous work North of Te Hana to determine the best route to take forward.
The Government has agreed in principle to an accelerated delivery strategy and we’re considering a wide range of funding, financing, and delivery tools to deliver this project quickly and cost effectively.
An emerging preferred corridor has been announced for the Northland Corridor for Te Hana to Port Marsden Highway and Port Marsden Highway to Whangārei.
An emerging preferred corridor is a larger area than the final route will be. Within the emerging preferred corridor there are still several different places the final road may go. The width of the area varies across the emerging preferred corridor due to geology and other constraints. The next step we do will be to refine this route further so we understand more about where the final road will go, and the land we may require for it.
We will start to reach out to potentially impacted landowners who are within the emerging preferred corridor to let them know the next steps. This will take some time due to the size of the project, but we are working hard to contact people as quickly as we can.
