Hingaia Road improvements Hingaia Road improvements

Auckland Transport (AT) is upgrading Hingaia Road in Karaka to support housing and employment growth in the area.

Project status: Construction (physical works)
Project zone: South

Project overview

AT worked closely with Auckland Council to identify the required transport network to support growth in the area. Much of the local roads and collector roads that will provide direct access to subdivisions and new builds will be done by private land developers. A number of arterial roads (roads intended to carry large volumes of traffic) will be delivered by AT.

Road improvements on Hingaia Road include:

  • Papaka Road construction.
  • Signalisation of the intersection with Kuhanui Drive/Hingaia Road and localised widening of Hingaia Road. These works are currently under construction and when complete will enable the removal of the existing pedestrian crossing to the school and the school's vehicle access to Hingaia Road.
  • Oakland Road/Hingaia road intersection signalisation.
  • Four lanes along Hingaia Road to Oakland Road.


Construction work started in April 2019 carried out by the project's contractor firm Higgins Contractors. It is scheduled to take 12 months to complete (weather permitting).

The project is being done in stages to minimise travel disruptions and maintain peak traffic movement:


  • July 2018 - Completed construction of new Papaka Road.
  • November 2018 - Stage 1 widening of Hingaia Road awarded to Higgins.
  • January 2019 - Watercare completed relocation/installation of watermain and rising main infrastructure.
  • April 2019 - Stage 1 work starts.

Project background

Hingaia Road is a district arterial road that provides a direct connection from Clarks Beach and Waiau Pa to the State Highway 1 (SH1) network and Auckland City. It also provides indirect connections from Patumahoe, Pukekohe and Waiuku to the SH1 network and Auckland City.

Due to its significance to the road network, Hingaia Road has been classified as a limited access road. The Hingaia Road-Oakland Road intersection currently experiences traffic issues and congestion especially in the morning peak.

The Hingaia-Oakland Road intersection forms part of the Hingaia Special Housing Area (SHA).

The Integrated Transport Assessment for the SHA identified the need to widen Hingaia Road to four lanes. This is an arterial road running through the centre of the peninsula connecting to SH 1 at the Papakura Interchange.


The improvement of the Hingaia-Oakland intersection and the widening of Hingaia Road will improve the movement of vehicles to and from the Papakura Motorway Interchange and enable further development in the Hingaia Peninsula and addresses traffic issues at the Hingaia-Oakland intersection.

  • The connections will improve accessibility for travel by other modes such as walking, cycling and public transport and provide travel alternatives for residents in the area and ease congestion.
  • Improve safety for the students and parents at Hingaia Peninsula School and ACG Strathallan.
  • Ensure traffic control and enable connectivity with Hingaia area.
  • Unlocks development to both north and south and protects traffic movement on arterial.
  • Benefits to existing schools which has been long planned and cannot be separated from SHA process.
  • Future benefits for those who would use the Hingaia-Oakland intersection to connect to Park Estate Road. 

Stage 1: 127 to 189 Hingaia Road

Stage 1 will be done in 3 construction phases from April to November 2019 (weather dependent). The scope of work is in between Bridgeview Road intersection to 189 Hingaia Road approximately.

Phase 1: South side of Hingaia Road

Enabling works start from 1 April – late September (weather dependent) with site set-up, service relocation work, footpath upgrade along the South-side of Hingaia Road and installation of new drainage pipe and rain gardens.

Phase 2: North side of Hingaia Road

Construction work will move to the Northern side of Hingaia Road and is schedule to start in late September – December 2019 . This will involve service relocation and footpath widening work.

Phase 3: Commission work

Installation of traffic lights at the Kuhanui Drive/Papaka Road intersection and localised widening work from November 2019 – January 2020.

Design features

Road widening

A key feature of the upgrade is the widening of Hingaia Road to a 4-lane road, one additional lane on both sides of the road. The proposed additional lanes will improve travel times for buses and vehicles and help reduce congestion along the existing traffic lanes.

Signalised intersection - Kuhanui Drive/Papaka Road

To reduce congestion and improve safety, Hingaia Road intersection with Kuhanui Drive/Papaka Road will be upgraded with:

  • traffic signals to provide more efficient traffic flow along Hingaia Road.
  • additional vehicle lanes on both sides to improve travel times.
  • new traffic signals at the entrance of the Kuhanui Drive/Papaka Road intersection.
  • controlled pedestrians crossing one on each side of the intersection to improve safety (especially for school children who regularly walk and cycle to school).

Flush median

Another key feature is the introduction of a painted flush median. During the scheme design stage, several options were assessed with varying lengths of solid median and flush median (painted white diagonal lines) along the centre of the roadway.

Analysis of crash data indicated a high number of crashes and near misses were the result of vehicles trying to turn right into Hingaia Road and out of access ways and driveways with the current 2-lane road layout.

The flush media will provides a wider separation between traffic streams on either side of the road. It also provides a refuge for vehicles turning into and out of driveways. Vehicles can use the flush median to slow down before making a right-hand turn, or to merge into a gap in the traffic flow.


All existing traffic movements on Hingaia Road will be maintained and a safe footpath will be maintained for pedestrians and cyclists to use at all times.

Generally, hours of work are 7am to 7pm, Monday to Friday. We may need to work outside these hours, and/or work at night on occasion. We will communicate these works in advance and will have a noise management plan in place to ensure disruption and inconvenience is minimised as much as possible.

As a live construction site traffic delays can be expected.

Road widening

In order to widen the road sections of Hingaia Road, it will be temporarily fenced and closed off for public access:

  • Detours will be in place and traffic controllers will be onsite.
  • Alternative footpath access for people and cyclist will be provided, there may be instances when they may be asked to use the other side of the road for their safety.
  • Traffic diversion signs will be sign-posted.
  • Property access and street parking maintained throughout the temporary closure unless works prohibit. Impacted properties will be directly contacted prior to restrictions taking place.
