Mount Maunganui property owner Sharon Waka's three-bedroom Pyes Pa home has been empty for almost two months and she is not rushing to advertise it again after a "gang" wanted to move in.
"I took these two guys to look at the house and five more turned up, all with patched leather jackets on," she said.
"One of them urinated on my flower garden as I was unlocking the front door to let them in to look, right in front of me. It was shocking."
