A police and Child, Youth and Family investigation is underway after a 9-month-old Rotorua baby suffered serious injuries, including head injuries.
The baby is in a serious but stable condition in Starship Hospital.
A police spokeswoman said an ambulance was called to a Korimako St house in Selwyn Heights about 6.15pm on Friday after a family member went to a neighbour for help. The baby was initially taken to Rotorua Hospital but was later flown to Auckland's Starship Hospital.
The police spokeswoman said the child was in the care of extended family at the time.
Rotorua police and Child, Youth and Family are currently investigating how the injuries happened and are liaising closely with medical experts. No arrests have been made.
