An Auckland landlady thought her nightmare ended when she managed to evict a "tenant from hell" from her $2 million St Heliers rental property.
Instead, it got worse after occupants who the tenant had sublet the house to refused to move.
The illegal tenants remain in her property and the desperate home owner is at a loss about what she can do.
Nina Zhao, 34, said her family bought the four-bedroom house as a rental property two years ago because they thought it would give them an "easy income".
They found a tenant after advertising the rental on local Chinese website Skykiwi.
She alleged her mother was assaulted and the occupant had made threats.
"I was really scared so I called the police," Zhao said.
The police came to the property, Zhao said, but they told her the matter was civil and not criminal.
The Herald sought comment from police yesterday but had not received a response last night.
New Zealand Property Investors Federation executive officer Andrew King said it was shocking that police wouldn't act.
"It is incredible that a young woman being told to take her pants off to get rent money owed isn't an illegal act and the police won't get involved," King said.
King said the waiting time for landlords to get a tribunal hearing and an eviction was eight weeks, and this was usually after an eight week wait for the original hearing and possession order.
"The long waiting time to get a Tenancy Tribunal hearing is poor service for both landlords and tenants," he said.
