Start–finish: June 2019 - ongoing in stages
Location: Sections through Mt Roskill, New Lynn and Titirangi

Upcoming works on McCullough Avenue, Mt Roskill
Our contractor is currently laying the watermain on Duke Street, Mt Roskill between the Duke Street/Mount Eden Road intersection, working their way towards the Duke Street/McCullough intersection. These works are progressing well, and we estimate this section to be finished by late October 2023 (weather dependent).
From Monday 9 October 2023 we will start works on McCullough Avenue and begin laying the watermain pipeline from the McCullough Avenue/Duke Street intersection working our way to the McCullough/Fyvie Avenue intersection. We estimate this section of works will take approximately three months to complete (weather dependent).
Please note, that Duke Street will remain closed with resident only access, as shown on the map below. As we progress closer towards the McCullough/Fyvie Avenue intersection, the works area and traffic management will change slightly from what is shown below. We will update this page once these changes come into effect.

Duke Street, Mt Roskill

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.
