A 3-year-old boy was found dead at an Auckland home on New Year’s Day, the Herald understands.  Emergency services were called to the villa at 9 Kerr St in Devonport about 11pm on January 1, where they found the boy’s body.  The property owners, believed to have been on holiday on Waiheke at the time of the incident, have declined to comment.  They are related to the dead boy, the Herald understands.  Police said last week that they were investigating the death but did not disclose the age or details of the person involved.  In a statement today, Detective Inspector Aaron Pascoe said, “While the circumstances around this incident are unexplained, there is no ongoing risk to the public.”  The body of a 3-year-old boy was found at a property in Kerr St, Devonport, on New Year's Day, the Herald understands.

The owners were on Waiheke, we had no idea who the people were, and that’s what is puzzling us all,” she told the Herald.  Police are investigating the unexplained death on Kerr St, Devonport. A neighbour said she heard an adult and children playing in the pool earlier in the day.

That’s what keeps playing on my mind,” she said.  Kerr St is a coveted, leafy address known for its mix of historic villas, cottages and character homes, close to the Devonport village.  Another neighbour told the Herald the street was a tight-knit community where “everybody knows everybody”.  Six neighbouring properties were formerly Kāinga Ora homes, sold into private ownership last year.  Yesterday, police issued a new appeal to the public in an effort to find the adult and at least two children believed to have used the pool at the house that day.  Detective Inspector Aaron Pascoe pictured in 2017.

He was charged with her murder, then found not guilty in 2024.  Pascoe has urged anyone with information about the Devonport death to contact police on 105 and quote the file number 260102/0177.  Carolyne Meng-Yee is an Auckland-based investigative journalist who won Best Documentary at the Voyager Media Awards in 2022.
