Slips, felled trees and debris continue to be a problem in and around the capital with roads closed and more rain due later in the week.
Wellington City Council chief infrastructure officer Siobhan Procter said 19 people whose houses were affected by slips were still in temporary accommodation or staying with family and friends.
"That's mostly as a result of houses that have got safety concerns as a result of the slips and are still awaiting inspections and whether they're deemed to be safe to return to or not."
There was still a risk of ground movement until there was a sustained period of dry weather she said, and full geotechnical assessments on some slips had to wait until the soil dried out somewhat. The road near a slip on The Terrace would remain closed for a "few days yet" while the ground was still sodden.
Hopefully rain forecast on Thursday would not be too heavy, Procter said.
Latest data showed there had been about 670 slips in the seven weeks since 1 July.
Of those, 170 came down between Thursday and Sunday alone.
There were hundreds of retaining walls maintained and renewed by the council
"We've had some significant work under way for the past five years or so which has looked at building or strengthening retaining walls which protect our emergency routes out of the city."
It was a continuation of a programme going on for decades, she said.
On the Kāpiti Coast a slip has closed the coastal road between Pukerua Bay and Paekākāriki.
Waka Kotahi says that stretch of road could be out of action for several weeks because the site is highly unstable.
Other large slips in the city were still of concern: Main Road in Tawa, the Pass of Branda, and Sutherland Crescent in Melrose.
Elsewhere in the North Island, slips have closed State Highway 1 through Mangamuka Gorge in Northland.
