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 2022

This will require a night-time full road closures on SH1 between the Kaipara Flats and Goatley Road and Hudson Road intersections. 

We need five full nights of road closures to complete this work.  At this time of year work is very weather dependent, so timings may change at short notice. Work that is unable to be completed during wet or very cold (<5c) weather will roll over to the next available fine night.

Please check back daily for updates.

Work commencing week of Sunday 07 August
  • Monday 8 August  - postponed

  • Wednesday 10  August  - Full closure SH1, detour in place, 9pm to 5am
When the full closure is in place, there will be a detour around Warkworth (via Woodcocks Road and Kaipara Flats Road). The detour will add up to 10 minutes travel time for some road users, so we advise planning ahead for travel over this time.

To keep up to date, you can check here on the website, or on the Facebook page @aratuhonopuhoitowarkworth or visit the Waka Kotahi Journey Planner - https://www.journeys.nzta.govt.nz/traffic/  before you travel.

The detour route will not be suitable for over-dimension vehicles, so drivers planning on using this route with over-dimension loads will need to prearrange escorts through the work site. If this affects you, please ensure you have the Waka Kotahi over dimension permit https://www.nzta.govt.nz/commercial-driving/permits/overweight-permits/application-for-an-overdimension-permit/ and then contact us via 0508 7295 4636 at least 48 hours prior to your planned journey.


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.
