Water and roading infrastructure in the city’s northwest is being upgraded to make sure these essential services continue to meet the needs of our growing communities.

Starting January 2026, pipe replacement and transport projects in the area will get underway as part of a coordinated work programme spanning two years.
The first project will start in January 2025, and the last project is expected to be completed in March 2028 and include:
- Ageing wastewater and water supply pipes are replaced and, in some cases, upsized to meet increasing demand.
- A new separated cycleway will be built on Matsons Avenue, connecting the recently constructed cycleway on Aorangi Road to Harewood Road as part of the NorWest Arc cycleway, and on the north side of Harewood Road as part of the Wheels to Wings Cycleway, connecting to the Northern Line cycleway.
- Street renewals and resurfacing will improve safety and traffic flow on Condell Avenue, Matsons Avenue and Harewood Road.
We know road works can be frustrating. Combining three waters and transport projects means we can plan the programme to reduce disruption, keep traffic flowing, and get out of the way as quickly as possible.
Projects starting in January 2026
The first two projects in the Northwest water and roading upgrades programme got underway in January 2026.
Work starts on Memorial Avenue before moving onto Greers Road and heading north to finish just short of the intersection with Wairakei Road.
The work on Memorial Avenue, between 216 and the Greers Road intersection, is expected to be finished by early February 2026. The whole project is due to be completed in July 2026.
Detours and other traffic management will be in place.
The start works notice(external link) has more details.
Work starts on Langdons Road between Oakland Street and the western entrance to Northlink. Traffic on this section of Langdons Road will follow a one-way system westbound.
After the work on Langdons Road has finished, our contractor will move onto Morrison Avenue and progress northwards to the Sawyers Arms Road intersection.
The Langdons Road component will be finished by mid-February, with the whole project due to be completed in mid-April 2026.
