South and East Auckland flooding summary November 2024.

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.

East Coast Road, Whakatiwai

Road status: open, single lane

We're designing repairs needed on East Coast Road. Construction is planned for 2025.

Hunua Gorge Road, Hunua

Road status: open

10 December 2024

We finished work on this road in mid-November. We thank the local community for their patience during these repairs.

8 November 2024

Work got underway at the start of October on Hunua Gorge Road. The slip will be repaired using a soil nail retaining wall with shotcrete. We expect to complete it by mid-November.

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.

Kemp Road, Awhitu

Road status: open

We're designing repairs needed on East Coast Road. Construction is planned for 2025.

Kohekohe Kariotahi Road, Waiuku

Road status: open

18 December 2024

We're designing repairs needed on Kohekohe Kariotahi Road. Construction is planned for 2025.

Manukau Heads Road, Awhitu Peninsula

Road status: closed, resident access only

10 December 2024

We've finished the design and a physical works tender has been released. We're now looking at tenders. We expect a successful contractor will be picked in January 2025. 

20 November 2024

We have advertised a physical works tender to realign the road around the section that was destroyed. This work will also include drainage pipes to redirect water and remove the risk of flooding damaging the new road.

We plan to begin construction in January. This will take 4 months to complete.

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.

Te Tero Road, Pollock

Status: Closed, residents’ access only during construction hours

Work on Te Tero Road started in November. The work includes the construction of:

  • a timber retaining wall
  • culvert
  • rock-lined side drain.  

A new guardrail will also be installed. We expect this work to be completed during December.

 

Timber piles for the new retaining wall being placed by heavy machinery.
A large timber retaining wall is under construction. The team have created a bench beneath the road to work from. An excavator holds the timber poles while it is positioned.

 

Union Road, Mauku

Road status: open

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.

Union Road resealed, with new barriers and line marking complete.

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.

Urquhart Road, Karaka

Road status: open
