Hawke's Bay police are investigating how a 10-week-old baby boy suffered significant non-accidental injuries.
The boy was admitted to Hawke's Bay Regional Hospital early last month after he was taken to a local GP by a family member, Detective Senior Sergeant Dave Greig said.
The injuries to his body could not have been received accidentally, he said.
The boy's family was from the Wellington area and they had only been temporarily living in Hawke's Bay.
"It's unclear at this point where the child's injuries occurred and our investigation will be looking into how the child received the injuries and when.
"We are speaking with family members to try and ascertain as many details as possible," Mr Greig said.
The child was put into Child Youth and Family care when he was discharged from hospital.
