The Whakatane District Council says the residents of seven properties evacuated on 18 August due to an unstable hillside still cannot go home.
Days of heavy rain threatened to dislodge a slip behind the dwellings on Muriwai Drive in Whakatane.
Two houses and a block of six apartments remain too dangerous to live in.
A playground and a toilet block are also closed.
Geotechnical experts say they need another seven to 10 days to complete their assessment of the slip and its implications.
