Concerns about the stability of local cliff faces after prolonged periods of rain this winter now extend to the roads above – in particular at a site on South Ave in Whangaparaoa.
Part of the road, which goes along the top of the cliffs at Little Manly, has been coned off and down to one lane for several weeks.
Local residents say that the road slowly sunk back in May and was repaired with a patch of asphalt in June.
They say it was not long before the asphalt repair cracked and the road slumped even further after more rain. Some are concerned about the potential impact of heavy traffic, including trucks and diggers, which have been using the road regularly while working on subdivisions at East Point.
Auckland Transport spokesperson Mark Hannan says that part of the road is in danger of slipping due to the heavy rain.
He says engineers have been on site investigating options for repairs and that the rest of the road is safe.
Mr Hannan says Auckland Transport is taking expert advice on the situation. This will include an investigation of the cliff above Little Manly to check its stability. There is the possibility that a retaining wall may need to be constructed to make the road safe.
