Northern Connection (Pukerito Roundabout)

Pukerito is where the new Ara Tūhono – Pūhoi to Warkworth motorway will connect with State Highway 1 (SH1) at the northern end, between Hudson Road and Kaipara Flats Road. Pukerito will be an important landmark, particularly to the residents of Warkworth and to travelers heading to and from Matakana, Whangarei, and the Far North.

The name Pukerito was gifted to the project by Hōkai Nuku. It can be translated as ‘middle hill’ and signifies the general area as a gully between two hills.

What are we doing?

Overview of the upcoming State Highway 1 road closures

As we progress towards completing the new motorway, we are now at the stage where we need to connect parts of the new road with the existing motorway and State Highway 1 (SH1), this means there will be several road closures on SH1 in both the north and the south during November and December.

We will start this work at the Northern Connection where the project team will carry out median island works and northbound widening works.  To carry out this work safely a series of road closures will be in place from 9pm to 5am

  • Sunday 20 November to Thursday 24 November (Detour via Kaipara Flats/Woodcocks Road)
  • Sunday 27 November to Thursday 1 December (Detour via SH16)
  • Sunday 4 December to Thursday 8 December (Detour via SH16)
  • Sunday 11 December to Thursday 15 December (Detour via Kaipara Flats/Woodcocks Road)

There is a wider network closure of SH1 from Wellsford to Warkworth (for work resurfacing) from Sunday 27 November to 1 December and again on Sunday 4 December to Thursday 8 December with a detour via SH16. 

Our project team and Waka Kotahi Maintenance teams are once again working together to ensure that we capitalise on these closures and get as much work done as possible in order to minimise disruptions.

While we will try to limit disruption to traffic flows, we encourage you to plan your journey over this time and check the Waka Kotahi Journey Planner before heading out

We appreciate the P2W project works have been ongoing and that residents have endured continued disruptions over the years. We are working hard to complete this work before the busy holiday period, and we will be off the road mid-December and back early in the new year, to apply the final OPGA road surface at the northern and southern ends.

Once again, we look forward to opening the project next year and we would like to thank our local neighbours and night-time road users for their patience while we undertake this important work to improve the safety and resilience of the network.




Located between Pukerito and Auckland Transport’s Matakana Link Road intersection is the Asset Maintenance & Management (AM&M) building. This is being built as a maintenance depot and office facilities for the ongoing maintenance and operation of this section of SH1.

The location was chosen next to the roundabout for ease of access to the main alignment and to provide better response times in case of emergencies on the motorway.

  • A multi-lane roundabout with three exit points: The north-bound exit (onto existing SH1), the east-bound exit (heading towards Warkworth), and the south-bound exit (entering the new motorway)
  • Widening of existing SH1 between the new roundabout and the SH1/Hudson Road intersection to provide two lanes in each direction (plus additional for turning movements)
  • A left turn slip lane from the motorway to exiting SH1 (northbound)
  • A left turn slip lane from the existing SH1 towards Warkworth (eastbound)
  • A left turn slip lane from Warkworth towards the motorway (southbound)
  • A shared walking and cycling path

Traffic signals

Two signalised road crossings will be installed: one for Matakana Link Road and the other on SH1 South.


The wetland forest which previously occupied the low-lying ground on the approach to the roundabout from the south will be regenerated. Planting around the northern roundabout will be bold and will include a selection of locally relevant indigenous specimens.
