This neighbour, who shared a boundary fence with the property, said the community and those close to the house would be feeling it.
"I think everyone's probably in shock and we're like, whoa... And it was only over the back, ya know?"
He, among the other residents RNZ spoke to, said they had heard nothing on Sunday evening or Monday morning.

Many of the residents along the street read about the homicide inquiry on the news before discovering the police presence on their street.
However, one resident divulged there had been arguments coming from the house in the days leading up to the deaths, but said it was nothing that raised alarm bells.
"This has sort of been going on and off for a few days now. You know, just the odd times we can hear people arguing."
He said on Sunday night his son and grandchildren were sleeping in a tent along the back of the property - but they didn't hear a peep.
"Yeah he said he didn't hear nothing. It was like he didn't even know the police were over there.
"But I mean we don't even know what the actual charge is because we didn't hear no gun or anything like that, so it could have been a stabbing."
One man from a neighbouring property was awake when police arrived and said it was a frightening ordeal.
"When I woke up at 2am, went out and had a smoke and let the cats out, and trying to get them in, I had the curtains all closed, next minute I see search lights and walkie talkies and a cop at the end of the driveway. It's a bit traumatising."
The man, who was visibly upset, said he just wanted to know what happened.
He knew that two people were dead, but more than two people lived in the house and he didn't know which two were killed.
He said not knowing was weighing heavily on his mind.
The man had spoken to the father of the house on Sunday night and had been expecting him to visit on Monday.
Forensic and ESR teams spent most of the day inside the house, occasionally emerging with evidence bags.
