This wastewater upgrade began in early September 2024, with work progressing along Clyde and Creyke roads before reaching the intersection at Ilam Road in mid-2025. 

From Thursday 10 July 2025, work will begin on Maidstone Road. The project is expected to wrap up by approximately mid-2026.

Current and upcoming phases of work

After work is complete at the intersection of Creyke, Ilam and Maidstone roads(external link) on Thursday 10 July, the traffic management currently in place will be removed.

  • Ilam Road will reopen on the northern approach to the intersection.
  • Creyke Road will reopen to two-way traffic.

Following this, work will progress along Maidstone Road, between Ilam Road and Waimairi Road. This will require a westbound one-way system through this block, which will be in place until approximately mid-2026. View the start works notice.(external link)

Traffic impacts

18 June to 10 July 2025:

A one-way system is currently in place on Creyke Road, between Clyde Road and Ilam Road, for westbound traffic. Signposted detours will direct eastbound traffic around the lane closure. The speed limit is reduced to 30km/h so we can keep our workers and everyone in the area safe.

There is also a no-entry/exit on the north side of the intersection of Creyke Road with Ilam Road and Maidstone Road. Signposted detours are in place.

10 July 2025 to mid-2026:

There will be a westbound one-way system on Maidstone Road, from Ilam Road to Waimairi Road, with no entry onto Maidstone Road from Waimairi Road.
