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).

Overnight closures are planned through Dome Valley in February for maintenance works.  There will be a full road closure (weather dependent) between 8pm and 5am on the nights of

  • Wednesday 8 February and Thursday 9 February
  • Sunday 12 February through to Thursday 16 February
  • Sunday 19 February through to Thursday 23 February

 As the Dome Valley works will close SH1 from Hudson Road, Warkworth through to Wellsford our Northern Connection team will be working a few nights within their two-week closure to complete paving and other finishing works. Our stakeholder team will liaise with any directly affected neighbours.

Journey planning
During these night works, SH1 will be closed to all traffic between Wellsford and Warkworth. A detour will be in place between Woodcocks Road, West Coast Road, Kaipara Coast Highway and Port Albert Road.  Those travelling between Auckland and Wellsford are advised to use SH16.

While all efforts have been made 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

These construction works connecting the Northern Connection and SH1 are part of the final stages before the new motorway can be opened. While this will impact travel, completion of these works takes us closer to opening the new motorway as soon as possible and we are all looking forward to enjoying a safer, more resilient and reliable road with more consistent travel times.




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.
