Middlemore Hospital has launched an investigation into how a baby came to be snatched by a woman who had faked her pregnancy.
The 24-year-old Fijian-Indian woman allegedly pretending to be pregnant for nine months.
Counties-Manukau police say the woman told her partner she was about to give birth to their child, so he dropped her off at Middlemore Hospital.
Police say the woman went inside and walked the corridors for several hours looking for a child she could call her own, before calling her partner to tell him she had had the baby.
Police say the woman carried a baby out of the hospital to a waiting car.
She had been handed the baby girl by a staff member who thought she was the mother.
The baby's parents saw the woman leave and alerted hospital
staff and the baby was retrieved.
The woman was arrested and charged and was granted bail after appearing in court last Thursday.
Counties-Manukau DHB spokeswoman Lauren Young says the hospital is looking into the incident, and will attempt to plug any holes in its security procedures.
