The Earthquake Commission says it is aware of about 200 slips that have occurred in the greater Auckland region in recent weeks.
While many of them are not serious, some are, including the most recent which happened at Albany on the North Shore.
Residents were evacuated from their properties overnight, yet more victims of Auckland's big wet.
"I thought it was a nightmare," says Simon van Tuyl, one of the evacuees. "I just thought well, you see it happen to other people but not yourself.
"You don't sort of expect that, backyard just disappears down the hill."
Mr Van Tuyl was working at home when the landslide struck. By the time he got outside his water tank had gone, and his storage container filled with precious work tools was close behind.
"So I rang a friend," says Mr van Tuyl. "He's got a 15-tonne digger here, an excavator, and we dragged it up the drive before it disappeared down the hill as well."
Mr Van Tuyl and his neighbours are the latest Auckland residents to be hit by an avalanche of landslides.
"There's been a number of significant slips, some of which have been reported in the previous weeks," says Malcolm Mendey of the Earthquake Commission. "I'm aware there's something of the order of 200 in greater Auckland region."
On the North Shore alone at least 20 families have been forced to evacuate. One house has already been demolished and at least four others might have to follow suit.
In Manukau, a massive slip has closed the main road to Kawakawa until at least Friday, and is threatening a nearby property.
And in central Auckland the fate of three multi-million dollar townhouses in St Mary's Bay hangs in the balance.
The reason for the earth movement is obvious: three months of almost non-stop rain.
The Auckland region has had 170mm of rain so far this month, already 50 percent more than the August average of 113mm.
This follows 214mm in July, 65 percent above average, and 158mm in June, 35 percent above average.
In total, over half a metre of rain has fallen across the city in just three months, and when you combine that amount of water with poor drainage and only 12 days of sunshine, you get something experts call "soggy soil syndrome".
Geo-technical engineers are now assessing the safety of all the properties affected by the latest landslides.
