Auckland Transport’s flood recovery team has repaired 83 per cent of the slips that occurred on local roads in south Auckland during the 2023 extreme weather events.
More than 2000 slips on local roads were reported to AT during this time across the Auckland region. Of these, 1200 smaller slips were fixed fairly quickly, but more than 800 bigger slips required extensive investigation to inform sustainable and resilient engineering design solutions.
In the south 30 complex slips needed repairing: nine minor (less than $250,000 to repair) and 21 major (more than $250,000 to repair).
By the end of May 2025, 56 per cent of minor slips and all but one major slip had been repaired, with one major slip currently under construction: Manukau Heads Road.
Alan Wallace, GM Road Asset Maintenance and Renewals at Auckland Transport says 25 slips have been fixed and three more will be repaired in the second half of the year: Ararimu Road, Cemetery Road, and East Coast Road.
“Last month we completed the repairs to the second slip site on Kemp Road in Āwhitu, and Urquhart Road in Karaka – both substantial slips which closed the road.”
Work to repair two slips on Kemp Road began in February; the first involved building a timber retaining wall and repairs to the road surface, while the second involved installing a soil nail retaining wall and drainage improvements.
Construction to re-establish the connection on Urquhart Road began in April 2025 and was completed last month. Work included the installation of new drainage across the road and the construction of a mechanically stabilised earth (MSE) wall to mitigate the slip. New rock armour on the face of the MSE wall now protects the road from further erosion.
