A landslide left a woman unable to leave her property overnight after it covered her driveway and a falling tree crushed her car.
Residents of two other houses in the Dunedin suburb of Blanket Bay on the shores of Otago Harbour were evacuated for safety reasons, Dunedin Senior Sergeant Ed Baker said.
The trapped woman contacted emergency services around 12.50am. A ladder was used so she could climb down out of her Blanket Bay Rd property.
"The slip came down through her driveway and onto Blanket Bay Rd, closing it," Baker said.
Occupants of another house on Blanket Bay Rd and one on nearby Strawberry Lane were evacuated for safety reasons.
Dunedin City Council roading maintenance engineer Peter Standring said the priority was to assess if there was any immediate threat to the woman's house.
A geotechnical assessment of the site of the slip would be carried out as soon as possible.
Access to some houses on Upper Junction Rd, above Blanket Bay Rd, may also be affected.
The slip started when part of the hillside from the top side of Upper Junction Rd fell on to the road and then continued down, Standring said.
Damage to Upper Junction Rd meant it would be closed to through traffic for months.
