Auckland Council's head of engineering resilience says it could be six months' wait for homeowners on two roads affected by landslips at Muriwai, before they know if they can live in their properties again.
Geotechnical engineer Ross Roberts told Checkpoint it will be one or two months before the future of the affected properties can be confirmed, as the earth around them is still unstable.
"It's going to vary depending on particularly how far they are from the slope... The ones further away from the slope, we're likely to be able to get a good idea, within a month or two... it really does depend on how those slopes respond to changes.
"It could certainly be longer... Examples from other areas around New Zealand have shown that where you get landslides, it can take six months or sometimes longer before you can actually have enough information to give people confidence to be able to get back into the homes in the worst locations."
There are 128 red-stickered properties in the West Auckland beach settlement, with an additional 48 yellow-stickered.
