Details

Project overview: This entire project will be completed in three stages and involves upgrading the wastewater pipes, installing a new stormwater network and making water supply upgrades; completing the northern-most section of the Nor’West Arc Cycleway (Ilam Road / Aorangi Road intersection to Matsons Avenue / Harewood Road intersection); and renewing Aorangi Road. For each stage/location, the package of work will be delivered together, with all work completed by mid-2026.

The Stage 1, phase 3 programme is located on Aorangi Road (south), between Wairakei Road and Brookside Terrace.

Phase 3 work scope:

 Major wastewater and underground service upgrades along Aorangi Road.

 Preparations for future kerb and channel, road and footpath renewals.

 Cycleway construction.  

 

At times, night work may be required. Prior to this happening, those who may be impacted by the work will receive further notification from the contractor.

 

This work overlaps some Stage 1, phase 2 works on Wairakei Road and Aorangi Road (north), which are still ongoing.

Phase 2 update

 

The transition back to two-way traffic on Wairakei Road is now expected to take place by the end of July. This delay is due to a combination of wet weather, challenging ground conditions, and higher than usual groundwater levels. These factors have required additional care during excavation and construction, particularly around critical work like manhole connections and trench backfilling. We’re sorry for any inconvenience caused by this delay.

 

Traffic Impacts

 

• The citybound one-way system on Wairakei Road will remain in place until end of July. A detour is in place for the airport-bound route.

 

• The existing closure at the southwest approach to the intersection of Wairakei Road and Aorangi Road will extend to just north of Colwyn Street until end of July, with access maintained for residents and businesses only. Access to Aorangi Road (south) will be maintained from the southwest end of the road and through side streets, such as Clyde Road and Brookside Terrace.

 

• Aorangi Road (north) will remain one-way system, with entry from Condell Avenue only and left-turn exit only onto Wairakei Road, until end of August. Detours are in place.
  Note: As this notice focuses on impacts in place between 26 May and end of July, this one-way system will be recaptured in the next start works notice, which will focus on the period starting end of July / beginning of August and ending in late October, when all Stage 1 works are expected to be complete.

 

Information for residents and businesses:

• There will be no on-street parking in the work area
