Huia 1 watermain upgrade

Watermain replacement to cater for population growth.

Start–finish: June 2019 - ongoing in stages
Location: Sections through Mt Roskill

What’s happening now?

Puketāpapa Mount Roskill area

From Monday 20 June, we will be working in Puketāpapa Reserve connecting into existing infrastructure at the base of the Maunga before heading across Dominion Road intersection. A temporary bike path and footpath will be installed by the entry to the Maunga for the duration of the project.

As we install the replacement pipeline across Dominion Road, traffic management will be in place with lane closures affecting two lanes at a time. General work hours will be between 7am to 6.30pm Monday to Friday, and 8am to 6pm on Saturdays. Noise levels and vibration will be managed in accordance with Council requirements.

From Monday 20 June: Stage 1 traffic management

  • Northbound is restricted to two lanes along Dominion Road while southbound along Dominion Road is not restricted (for a period of approximately 2-3 months)
  • Following the works in Puketāpapa there will be approximately a month of work working across Dominion Road. This will involve some lane closures.

Working with you

We understand that construction for major projects such as the replacement of the Hūia 1 watermain can be disruptive at times. We aim to be a good neighbour while we are working in your area. We will work with you to minimise disruption where possible and will keep you informed with what’s happening. We will be out in your community during the works ensuring signage and information is clear for residents and road users. If you have any questions about this project reach out to us at [email protected] Please note that water supply to properties will not be affected during the upgrade.


Highland Avenue residents

From 25 May, Highland Avenue will be fully closed with resident access only for Highland Avenue and Deane Avenue for approximately four months. Click here to view the traffic notice.


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.

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.​
