"There they were down the bottom looking up at me," she said. "They would have had a hell of a ride."
Ms Holmes and Mr Watson are now waiting to hear from their insurers, the Earthquake Commission and Tauranga City Council engineers, but are still able to live in their home.
Ms Holmes said the soil had been left sodden by bad weather, at a time when trees that had grown tall and heavy were being buffeted by heavy southwesterly winds.
"The rain was consistent for such a long time and the ground just didn't have time to dry out."
Despite its size, the slip had eaten away little of their section, she said.
"It looks okay but if we get another three months of rain, there's a risk in the future that more erosion will continue."
The Tauranga City Council's manager of city development, Paul Baunton, said the landslide was a typical erosion type of slip. "It looks dramatic because of its height but the depth of it is not that large - probably no more than a metre."
He said he had been called to a slip involving one of the other houses two weeks ago. Council officers would now be monitoring the site several times a week.
