Ara Tūhono – Pūhoi to Wellsford

Section menu

Project introduction

This project is to improve State Highway 1 between Pūhoi and Wellsford in the northern Auckland region.

  • Estimated project cost

    $100 million +


The Ara Tūhono – Pūhoi to Wellsford road of national significance runs approximately 38 kilometres through the Rodney area north of Auckland on State Highway 1. The project aims to extend the Northern Motorway (SH1) from the Johnstone's Hill tunnels just south of Pūhoi to a point north of Wellsford. Existing and anticipated future regional growth will provide opportunities for economic and social development in Northland and provide a better connection to Auckland for freight, tourism and motorists.


Ara Tūhono – Pūhoi to Wellsford road has a strategic role looking at connecting Auckland and Northland and looking to future regional growth, as well as improving the safety of the route and making journey times more reliable.

The objectives for the project are:

  • to enhance inter regional and national economic growth and productivity
  • to improve movement of freight and people between Auckland and Northland
  • to improve the connectivity between the growth areas in the northern Rodney area
  • to improve the reliability of the transport network through a more robust and safer road between Auckland and Northland.

Other benefits include reducing congestion during peak periods, and improving economic development and tourism opportunities in Northland.
