PUKERITO ROUNDABOUT (The Northern Connection)

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

The Ara Tūhono – Pūhoi to Warkworth project will be undertaking pavement reconstruction and tie in works on SH1 between the Kaipara Flats Road, Goatley Road and Hudson Road intersections. A section of SH1 will be closed at various times, during July, August and September, while we carry out this work - to ensure the safety of our teams working at night and all other road users. 

As our team progress works at Pukerito (Northern Connection), pavement reconstruction and resurfacing works are required. As part of these works, the intersection at Kaipara Flats Road, Goatley Road and State Highway 1 (SH1) has been upgraded. New barriers have been installed and an extra median lane will be introduced as part of the final design, allowing vehicles to safely merge when turning onto SH1 southbound.

What you need to know  -

August – September 2022

State Highway 1 will be closed to all traffic in both directions from Wellsford to the Hudson Road intersection for 10 nights over a two-week period this month to allow the project team to complete the work.  Followed by one night to switch the traffic around the new Pukerito roundabout.

The closures will be in place between 9pm and 5am

  • Sunday 21 August to Thursday 25 August – Full SH1 closure Warkworth to Wellsford, detour via SH16
  • Sunday 28 August to Thursday 1 September - Full SH1 closure Warkworth to Wellsford, detour via SH16
  • Sunday 4 September – Full SH1 closure, detour via Hudson Road

 There will be a detour in place via State Highway 16 from Wellsford to Woodcocks Road, Warkworth.  This detour will add up to 30 minutes extra to the journey.  If you are travelling north, you can exit the motorway at Silverdale to SH16 and avoid the Warkworth area.  We advise planning travel over this time carefully and apologies for any inconvenience caused. 

Please plan ahead for your journey during this time and check the Waka Kotahi Journey Planner https://www.journeys.nzta.govt.nz/traffic/  before you travel.

Over dimension loads will not be able to use the detour route, therefore we have a special arrangement in place where over dimension vehicles will be able to access through the work site at a set time on set days.  Please contact us 48 hours or more before your journey on 0508 P2WK INFO (0508 7295 4636) or at info@nx2group.com.  Heavy vehicles can use the detour route, and it is suggested you exit at Silverdale.

 Once we complete this piece of work, we’ll be back on Sunday 4 September to complete the traffic switch and a further road closure will be needed that night. A much shorter detour via Hudson Road will be in place while we do this work.  After the switch has taken place, the road surface will be a lot smoother.

There will be further closures in this area each month until the end of the year, to complete the tie in and place the final OGPA pavement surface.  These closures will be for a few days at a time, and the detour shorter, via Hudson Road.




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.
