Project introduction

The Warkworth to Wellsford project is the second section of Ara Tūhono – Pūhoi to Wellsford project. The project is in an investigation phase with lodgement of designation and consents currently planned for April–June 2019.

January 2020 update

Waka Kotahi NZ Transport Agency has completed the work necessary for a proposed designation of land to be put in place for a new road transport corridor between Warkworth and Te Hana, to be constructed at some time in the future.

A Notice of Requirement and resource consent applications are scheduled to be lodged with Auckland Council in March.

The Warkworth to Wellsford application is the culmination of three years of project development which has included preliminary engineering design, site investigations, transport planning, technical assessments and stakeholder engagement.

The Transport Agency will communicate this project milestone via a media release, once Council has accepted the application.

The application documents will then be published online and available to read at local libraries shortly after.

About this project

The Warkworth to Wellsford project is the second stage of Ara Tūhono Pūhoi to Wellsford. Stage one, between Pūhoi and Warkworth, is currently under construction, with a completion date of late-2021.

An off-line highway, completely separate from the current SH1 remains the preferred long-term option between Warkworth and Wellsford and the Transport Agency is continuing to investigate this second stage of Ara Tūhono Pūhoi to Wellsford project.

The indicative alignment

The indicative alignment for Warkworth to Wellsford connects to the Pūhoi to Warkworth section to the northwest of Warkworth and heads north, crossing Woodcocks and Kaipara Flats Roads.

The new highway will be located in a separate valley, to the west of the existing SH1, until it reaches the Hoteo River where it will head eastwards crossing over the existing SH1and Wayby Valley Road, with an interchange proposed at Wayby Valley Road.

The highway then continues generally parallel to Wayby Valley Road, before turning northwards and crossing Rustybrook Road. As the highway heads north it will cross local roads including Whangaripo Valley, Farmers Lime and Silver Hill roads, bypassing both Wellsford and Te Hana townships.

A further interchange is proposed near Mangawhai Road, with the new highway then connecting back into the existing SH1 to the north of Waimanu Road.


There will be a number of transport benefits as a result of the project including:

  • Improved travel time between Warkworth, Wellsford and Te Hana
  • Reduced heavy traffic on SH1 through Wellsford and Te Hana, with the removal of nearly 1000 heavy vehicles per day
  • Reduced congestion through the Wellsford main street
  • A high quality, safe new route with improved geometry and gradients
  • Efficient connection to the Warkworth and Wellsford town centres through well located and convenient interchanges
  • Improved corridor resilience through the provision of a reliable additional route separate to the existing SH1.

What happens next?

Public information days will be held in February 2019 to present information on the indicative alignment for Warkworth to Wellsford.

The Transport Agency intends serving a Notice of Requirement and lodging consent applications to Auckland Council in the second quarter (April-June 2019).

Project phase

  • Route investigation and community consultation (2010)

    The project team, working with consultants Sinclair Knight Merz (now Jacobs), completed a detailed study of the Pūhoi to Wellsford route.

    Community input was sought through two rounds of consultation. The first round of engagement was undertaken between 1 June and 16 August 2010. A lot of feedback was received and a map summarising feedback was prepared.

    As a result of this consultation, a decision was made by the Transport Agency to separate the project into two sections - Pūhoi to Warkworth and Warkworth to Wellsford.

    A second round of consultation on Pūhoi to Warkworth took place between 16 November 2010 and 28 January 2011, with feedback and subsequent information on the project available on the  Pūhoi to Warkworth webpage.

    Due to the difficult terrain in the Dome Valley and ground conditions near Wellsford, the Warkworth to Wellsford section of the project was put on hold in 2010, pending further investigation work.

  • Identifying an Indicative Route (2016)

    Investigations into the Warkworth to Wellsford section recommenced in 2016 with a project  team, including members of the 2009-2010 Sinclair Knight Merz (now Jacobs) team, reviewing all previous investigations works undertaken to date.

    Comprehensive technical assessments of the original ‘long list’ of options is expected to take nine months to complete, with the expectation that these investigations will identify an Indicative Route to take forward for public consultation early-2017.

    Once identified, the indicative route will be discussed with all potentially affected landowners first, then presented to the wider communities of Warkworth and Wellsford for feedback.

  • Confirming an Indicative Alignment (2018)

    We have refined the Indicative Route presented publicly in February 2017 to what is now called the Indicative Alignment within the proposed designation boundary.

    The proposed designation boundary will be the area of land that the Transport Agency is proposing to designate for the construction, operation and maintenance of the Project.

    It includes land which may be required for design refinements and for temporary construction activities such as access roads, construction yards and erosion and sediment control.

  • Obtaining statutory approvals (2019)

    The findings of investigations into the Warkworth to Wellsford indicative route have been considered alongside input from landowners, iwi, stakeholders and local communities to announce an indicative alignment in late-2018.

    The next step is to protect the land needed for the new road by lodging a Notice of Requirement (NoR) in mid-2019.

    The NoR and resource consents will be lodged with Auckland Council, who will notify affected parties and the public approximately 1-3months after they receive our application.
