Southern District Health Board is reviewing the care it gave an Invercargill mother whose three-week-old baby girl received life threatening injuries on Monday morning.
Police have begun a criminal investigation into the injuries and have interviewed the girl's parents, who were at home when the incident occurred.
The newborn remains in an induced coma at Starship Children's Hospital in Auckland.
Southern DHB chief executive Carole Heatly would only say it is conducting a thorough review of the quality of care the baby's mother received.
Ms Heatly says if her care was not safe or high quality it will take action to improve its service.
