Huia 1 Watermain pipeline upgrade

One of Auckland’s main water supply pipeworks from the west is being replaced with a larger pipe to cater for future population growth.

Start–finish: June 2019 - ongoing in stages
Location: Sections along Golf Road and Mt Albert Road

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.

Traffic management measures in place

Golf Road
Works commenced in July 2019 along Golf Road and are progressing well. Traffic management will continue into the New Year as we work our way down the road. We are working as quickly and safely as possible to re-open roads.
Mt Albert Road
From 27 December 2019 to end of January 2020, a new water pipe is being constructed in a section of Mt Albert Road. Traffic management will be in place during this time. Road diversions will be in place on Mt Albert Road between Frost Street and Winstone Road. Click here for more information.

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.
