The Pūhoi to Warkworth project will extend the four-lane Northern Motorway (SH1) 18.5km from the Johnstone’s Hill tunnels to just north of Warkworth. It is the first stage of the Ara Tūhono – Pūhoi to Wellsford Road of National Significance.
SH1 between Pūhoi and Warkworth is a key transport link connecting the north to the upper North Island freight triangle of Auckland, Waikato and Tauranga. The route is part of the Roads of National Significance programme that the New Zealand Government has established to move people and freight between and within major centres more safely and efficiently.
In November 2016, the Transport Agency awarded a Public Private Partnership (PPP) contract to the Northern Express Group (NX2) for the project. Under the PPP contract, the Northern Express Group will finance, design, construct, manage and maintain the Pūhoi to Warkworth motorway for the 25 years that will follow the expected five-year period to build the motorway. Full ownership of the highway will remain with the public sector. The Pūhoi to Warkworth motorway will open to traffic in late 2021.

For information about the previous investigation, consenting and procurement phases of the project, please read the project phases sections below.
The project team, working with consultants Sinclair Knight Merz (SKM), completed a detailed study of the route in 2010 and 2011. The study considered all issues associated with the road’s construction from the technical, environmental and community perspectives. The topics examined in the study included:
Location and form of road improvements
Social impacts such as noise, air quality and the effect on the local community
Tangata whenua and the cultural impacts of potential routes
Property impacts
Geotechnical and topography considerations
Ecological impacts and the effect on historic areas
Connections to the local roading network and walking and cycling access
Staging and costs
Opportunities to accelerate the project
Community input was sought through two rounds of consultation. The first round associated with the route investigation was carried out between 21 June and 16 August 2010. A large amount of feedback was received and a map summarising feedback [PDF, 347 KB] (external link) was prepared.
The second round of consultation took place between 16 November 2010 and 28 January 2011 with the release of the indicative route for the Pūhoi to Warkworth section. Again a large amount of feedback was received and this is summarised in newsletter 5 [PDF, 430 KB].
The findings of investigations into the Pūhoi to Warkworth section of the route were considered alongside community feedback to announce a preferred route in April 2012. For more information on the Pūhoi to Warkworth preferred route please read newsletter 6 [PDF, 527 KB].
CloseDetailed reports that outlined the potential environmental effects of the project were lodged with the Environmental Protection Authority (EPA) at the end of August 2013 to support the Notice of Requirement application to build the road.
The EPA notified and collected submissions on the Pūhoi to Warkworth proposal between 16 November and 13 December 2013. An independent Board of Inquiry heard submissions from the public at a hearing between 7 April and 5 June 2014. The Board confirmed the designation and resource consents on 12 September 2014.
