Start–finish: June 2019 - ongoing in stages
Location: Sections along White Swan Road and Golf Road
What’s happening now?
White Swan Road (from Pascoe Street intersection to Hillsborough Road intersection)
We are inserting the pipeline along the northern side of White Swan Road from 12 July for four months. White Swan Road will be one lane during the works, with detours on north-east bound traffic via Hillsborough Road and Dominion Road.

We will start inserting the pipeline from 12 July at Marshall Liang Avenue (during the school holidays) and it will take approximately four months to complete this section of road (moving along the road as we insert the pipeline and reinstate behind us).
Golf Road (at Gilliam Street intersection)
We are building a chamber and completing connections on White Swan Road to complete the pipeline installation. Golf Road will be one lane during the works, with traffic managed by signals or traffic lights for traffic both ways. Gilliam Street will be closed at the intersection for through traffic. We will start work from 13 July and take approximately four months to complete. The connections could not have been done during the pipeline construction due to the drought and water restrictions that were in place.

Why are we doing this?
We are renewing the large-diameter watermain called Huia No.1 which has reached the end of its useful life. The watermain was built in the 1940s after World War II. To extend its life we rehabilitated the watermain in the 1980s but we now need to build a new pipe. Over the next few years, the 17km pipe is being built in sections across West and Central Auckland. We thank you for your patience and understanding while we undertake these essential works.

Watling Street to the Gillies Avenue/Kimberly Avenue intersection
Next we will be undertaking service investigations to complete the construction design and methodology. Residents will be updated once the works have been confirmed.
Scout Avenue to Duke Street
We will soon be undertaking construction of the watermain. Work will start along Scout Avenue from the Mt Albert Road intersection towards McCullough Avenue and Duke Street. Residents will be advised of the timing of construction once it is confirmed. Click here for the latest newsletter.
We have completed pipeline installation from Winstone Street to Bremner Avenue. We will need to return to undertake works in John Moore Park for custodial protection of the new pipeline with access from Bremner Avenue. Residents will be advised of construction once it is confirmed.
We are currently piping a section of the pipeline under a culvert in the road, and aim to complete it by the end of June. The rest of the pipeline has been installed. There will be some closures on Memorial Avenue for an additional line-valve that needs to be added later.
Mount Roskill Reserve
Connection and pipeline work needs to be completed in the Reserve. There will be some tree removal for construction. Click here for more information.
White Swan Road (between Pascoe Street and Hillsborough Road intersections)
From 12 July, we will be starting construction of the pipeline. The work will start near Marshall Liang Avenue during the school holidays to minimise the impact on the school. We will then move to other parts of this section. Traffic management will be in place. The road will be one-way in a south-west direction, with detours for north-east bound traffic via Hillsborough Road and Dominion Road. Expect delays and take alternative routes where possible.
We have completed pipeline installation along Golf Road and the road is now open to through traffic. We will need to return to complete localised connection work at the intersections of Titirangi Road, Gilliam Street, Astley Avenue and Portage Road.
Donovan Street and White Swan Road
We are currently looking at design methodology for this section. Residents, businesses and community members will be notified once we have confirmed the design and timing of the works.
The timing of the works and traffic management plans are yet to be completed. Residents and commuters will be updated once the works have been confirmed. Click here for the latest newsletter.
General traffic management FAQs
Q: Why do we not have tidal flow (changing of traffic flows during the day and night)?
A: Tidal flow is a viable option where there are multiple lanes that can be changed i.e. Whangaparaoa Peninsula. Where there is only one lane through residential streets, tidal flow is not feasible. It is not safe for local residents as traffic flows change during the day and confusion around traffic direction could occur.
Q: Why don’t we use traffic lights or stop-go operations?
A: This is not feasible due to the length of the work sites. Traffic queues would become too long making it less efficient than one way traffic.
Q: How will we notify road users?
A: VMS digital sign boards are the most effective way to communicate with road users. In advance of the works we implemented VMS boards.
