Another neighbour who lived on the street behind the house said she had never heard arguments or been concerned about the family.

“They’ve been in contact with us in the past and they seemed nice.

“They were happy and a wonderful family. I believe they recently had a baby.”

Waitematā CIB Detective Inspector Callum McNeill said officers were in attendance after a person died and a second person had suffered injuries in Silverdale on Tuesday afternoon.

“At this stage, the death is being treated as unexplained,” he said.

“A second person has been transported to hospital in a serious condition.”

McNeill said police were in the very early stages of making inquiries into the circumstances of what had occurred.

“We can reassure the community we are not currently seeking anyone else in relation.”

The house where police focused their investigation is part of a sprawling subdivision in Silverdale, about 30km north of Auckland.
