A baby boy remains stable in Tauranga Hospital more than three weeks after sustaining injuries police described as "non-accidental" and shocking.
A police investigation started after an incident on December 30 at a Welcome Bay address.
The then three-and-half-week-old baby was taken to Tauranga Hospital then flown to Starship Hospital in Auckland.
He has since returned to Tauranga Hospital.
Detective Senior Sergeant Greg Turner of the Tauranga CIB said no one had been arrested and the investigation was continuing.
