Wellington City Council says two properties on the edge of a big slip in the city are likely to be demolished.
A landslip in the suburb of Kingston forced residents from their homes two weeks ago.
The council's acting civil defence controller Neville Brown says two properties on Priscilla Crescent will probably have to go.
"Certainly the two precarious ones that are right on the edge, I would say that is highly likely. But it's not our decision, it'll be a decision for EQC and the respective insurance companies, in due course."
But there was good news for the residents of three properties on Priscilla Crescent and Breton Grove as they learned they could return to their homes this weekend.
However, the council still wants them to monitor the properties for land movements.
Residents from a further three houses can go back, but only to retrieve items, until geotechnical assessments give properties the all clear.
Council spokesperson Richard MacLean says security guards remain at the site and will continue to patrol the area until further notice.
