East & South Auckland flood recovery progress East & South Auckland flood recovery progress
Extreme weather events in Tāmaki Makaurau / Auckland caused damage to roads in 2023.
Over the last 18 months or so, we have made significant progress on repairing storm-damaged roads in the East and South Auckland area.
Reported sites and slip repairs in East and South Auckland as of 30 September 2024.
- Total number of sites: 30 (21 major, 9 minor).
- Currently under construction: 2.
- Completed sites: 17 (57%).
We have completed:
- 13 out of 21 major slip repairs (62%)
- 4 out of 9 minor slip repairs (44%).
There are 2 major sites under construction:
- Hunua Gorge Road, Hunua
- Union Road, Makau.
The reported number of sites requiring minor to major repairs will change slightly over time as the design and investigation of each slip site develops.
We ask for your patience as we repair sites all over Auckland.
To report new issues, please contact us.

16 October 2024
Work is underway on Hunua Gorge Road to repair the slip using a soil-nail retaining wall. This week, the team will be undertaking shotcrete work. The team are on track to complete the repairs by the end of October.
9 July 2024
Design is complete, and we are looking to resource construction in September. Traffic management has been changed to allow for 2-way traffic flow.
Manukau Heads Road, Awhitu Peninsula
Road status: closed, resident access only
9 July 2024
Design and project planning continues.
14 February 2024
The project team has completed geotechnical testing and a hydrology assessment. Their recommendation is to reestablish the road link by building a short road bypass at the slip site. Preparation of the detailed design and resource consent is under way. The project will include stormwater work to prevent storms from causing the same damage in the future.
20 July 2023
- A safety fence to restrict access at the slip location has been installed.
- ‘No access to lighthouse’ signage has been installed.
- The local access gate has been upgraded, for use by residents only.
17 May 2023
On Manukau Heads Road, Awhitu Peninsula, a major slip occurred just a few hundred metres from the Manukau Lighthouse. The slip severed the road connection, and public access to the lighthouse and nearby properties is unavailable. The following aerial photo shows the extent of the slip, which extends approximately 80 metres downwards from the road.
An estimated 90,000 cubic metres of soil moved during the slip.
Initial assessment
The initial assessment indicates that stabilising the slip and restoring the road connection will not be a short process. A robust evaluation of repair options and site investigations are needed to ensure that the correct information informs decision-making before funds are committed to the design and construction of a permanent solution.
With restoration of the road connection being 12 to 18 months away, discussion around whether temporary public access should be restored in the interim is needed. This will also be a lengthy process because it involves land that AT does not own.
The most recent traffic data indicates that during the summer of 2020 (before the slip), about 240 vehicles travelled to the lighthouse per day.
Manukau Lighthouse
Road access to the lighthouse remains closed to the public.
McNicol Road, Clevedon
Road status: open
8 November 2024
Work started early September to repair the slip on this road. We installed 2 small retaining walls and rock armour protection. We finished work on this road in early October. AT and our contractor would like to thank the local community for their patience during these repairs.
9 September 2024
Work started this month on two small retaining walls and rock armour protection to repair the slip on this road. We expect to complete repairs within the month.
9 July 2024
Design is in progress, and AT is looking for options to restore access to all motorists. This road provides access to one resident only.
Union Road, Mauku
Road status: open, single lane operating
8 November 2024
We completed work at Union Road. We installed a new stormwater pipe and resealed the road. AT and our contractor would like to thank the local community for their patience during these repairs.

16 October 2024
Work started on Union Road at the beginning of October. The team are now working on pipe installation. They will then backfill behind the retaining wall. We expect to complete works at the end of the month.
9 July 2024
Design is complete, and we expect to start work at the site in September or October.
