The neighbour said he had seen Mr Tamaki several times at Ms Collins' house and noticed his truck when the church leader went hunting.
"Everyone I've spoken to says he's a really good guy. He does so much good work."
Another neighbour confirmed Bishop Tamaki moved into Ms Collins' house earlier this year.
"He said he was moving in there to rent it. I think he's got family there. I don't know if they're grandchildren or sons but there's definitely people there."
The woman had read reports about Mr Tamaki's "gay power" comments but had not discussed his views in person.
"We're not that close but we've said hello in the past. He's always been very nice to me so I don't have a problem with him."
Another source close to the couple said they were likely renting until they found the ultimate home to buy. The Tamakis had "heaps of visitors" and grandchildren who regularly stayed.
A Destiny spokeswoman confirmed the Tamakis were renting the property but said they were unavailable and did not wish to respond.
Ms Collins' luxury beach home on Omana Heights Drive failed to sell at auction in October - passed in after a single $1.9 million bid.
She co-owns the property with her husband, Oravida director David Wong-Tung.
The power couple bought a new five-bedroom home in St Heliers in February last year valued at $2.25 million and also own property in Nelson and Wellington.
According to Quotable Value, they paid $1.17 million for the Maraetai house in 2006 and had been hoping to sell it for "north of $2 million".
After failing to sell, the property was relisted with another agency, but the second listing was removed from Trade Me last month.
A source told the Herald Ms Collins took the house off the market due to a lack of acceptable offers and had planned to keep using it as a beach house.
"She wasn't about to give it away."
Ms Collins did not respond to requests for comment.
