Kia ora, welcome to the Arawa Avenue slip repair project page. Here, you’ll find everything you need to know about the project, including latest updates, and a timeline of upcoming steps.

About the project

During a weather event in June 2023, a slip developed at the upper end of Arawa Avenue, around 400m from the intersection with Wilson Road North.

Work to repair the slip began on the week of 4 May 2026 - this work is expected to be finished by mid-June 2026, weather dependent.

Given the known archaeological significance of the site, specialist oversight is in place throughout the project.

We appreciate the community’s patience while we carry out this work safely and manage the site with the care it requires.

What's happening now? (25 June 2026)

Everything is pretty much finished, with just some minor tidy-up work and line marking remaining.

Thanks to everyone for your patience while we completed this important repair work.


18 June 2026

Work is now entering the final stages.

Last week, we filled in behind the kerb and channel with topsoil, and prepared the road foundation ready for chipseal.

This week, we’re doing compaction tests on the road ahead of chipsealing, which is planned for Friday, weather permitting.

Once the road surface is done, there will just be minor finishing works and the site tidy-up left to do.


8 June 2026

We’ve finished building and backfilling the retaining wall, and the new kerb and channel has been installed.

Next up we’ll be backfilling the kerb, and installing riprap to help protect the area from erosion.

Since no kōiwi were found during the excavation, it is very unlikely that a full road closure will be needed to complete the work, however Stop/Go traffic management remains in place.


22 May 2026

The excavation works and archaeological investigation have been completed, and we're getting ready to install timber poles and build a retaining wall.

Kōiwi were previously discovered in the slipped material, but no koiwi were found during this work. The archaeologist has however taken some samples of the midden that was showing in the slip.

The weather has been kind to us so far, and the work is running to schedule.

1 May 2026

Work will begin the week of 4 May, 2026, to repair a roadside slip on Arawa Avenue.

Due to archaeological investigations, the road may at times be closed to traffic, however it will not be closed for the full duration of the project, which is expected to take 6-8 weeks to complete, weather dependent.

Detours will be in place along little Waihī Road and Wilson Road North while the road is closed and the site will be under Stop/Go traffic management at other times during the project.

The slip developed during a weather event in June 2023 and is located at the upper end of Arawa Avenue, around 400m from the intersection with Wilson Road North.

A midden is visible within the slip, and kōiwi were previously discovered in the slipped material.

Given the known archaeological significance of the site, specialist oversight will be in place throughout the project. If any further kōiwi are uncovered, work will stop immediately and appropriate protocols will be followed in partnership with mana whenua.

The contractor completing the work, J Swap, is also currently working on Wilson Road North. We know these works may cause some disruption, so we’ve made sure Arawa Avenue and Wilson Road North won’t be closed at the same time.
