The property was up a driveway off which a man in his 70s reportedly owns five of the six homes. The owner of the sole other property off the driveway saw the alleged open home yesterday afternoon and confronted the group of three.
"Who are you people? We're under quarantine for four weeks. Are you showing these people through your home?" the neighbour asks while recording on his phone.
The owner's neighbour, who wished not to be named, told the Herald the encounter was upsetting and aggravating.
"The property is vacant and today he's been renovating it. He's been beavering away for months. Doing it up and painting it and that kind of stuff," he said.
"He's selling the property privately. He sold my house to me privately - he used to own it.
"And today I was on the phone with someone and I was looking outside and I was like 'oh that's weird, [he] is having a laugh and being very jovial with these people in the backyard and showing them around and I thought this looks like an open home.
"So I walked down the driveway and when they walked out I was like 'hey, what are you guys doing? What's going on here?' At that point he said 'it's none of your business'.
But the property owner told the Herald his neighbour had the wrong end of the stick - the couple were family friends who were visiting his wife, who has dementia. While visiting, he also showed them around the neighbouring vacant house, which he was doing up for resale.
"The visit shouldn't have happened - we shouldn't have done it," he acknowledged. "They came in for a few minutes then we realised it wasn't right and they left."
But he said it was none of his neighbour's business.
The neighbour said the property owner met his questions with "hostility".
"He told me that he was going to call the cops. So insanely bizarre that he's conducting this open home," the neighbour said.
"I didn't want to get within a few metres of them. So I stayed up near my property. I've been very diligent about keeping within the parameters of what you can do. I don't even want to go to the supermarket."
The resident said he was quite emotional following the exchange, which was particularly brought on by his own concern for his business in the Covid-19 economic fallout.
On March 25, the Real Estate Institute of New Zealand (REINZ) told the profession that real estate is not considered an essential service and that open homes/private viewings cannot take place in person.
It said open homes could take place via online virtual tours or video conferencing software, where people do not have to leave their homes and no in-person contact occurs.
