The one-year-old boy found dead in a Rotorua home last week has been named, after a woman was charged with assaulting the child.
He was named as Trent James Matthews, also known as Michael Matthews.
Police inquiries into the cause of his death are continuing.
A 29-year-old woman appeared in Rotorua District Court on Saturday and was granted bail, reported The Daily Post.
Police will not say what the relationship between the boy and the woman is.
It is understood emergency services were called to the Edmund Road house about 7.30am on Friday and found the toddler's body in the lounge.
Detective Senior Sergeant Mark Loper said results from a post-mortem examination on the boy's body had been inconclusive and it was unclear how he had died.
Mr Loper said there had been no history of family violence at the house and the family had co-operated with police.
"All the family are devastated, totally devastated," he told The Daily Post.
"We don't know whether it is a child-abuse death at this point. Exactly how the child died, we are not sure about. Until the forensics come back, we cannot join those dots."
The boy's body has been been released to his family and a tangi will be held in Kaitaia, where his family is from, the Daily Post said.
The accused is due to reappear in court on Wednesday.
