Child, Youth and Family has apologised for "tragic and unacceptable" failings that led to the indecent assault of a 13-year-old girl by one of its own carers.
The girl is one of nine children who the Herald on Sunday has learned died or were seriously harmed in CYF care over the past five years.
A 61-year-old CYF caregiver, Rotorua man Norman Scott, has been convicted and sentenced for indecently assaulting the girl in his care.
The same week that the agency disclosed the cases in response to an Official Information Act request, a 10th child died while on the run from CYF care. Isaiah Nathan, 13, was killed when he crashed a car in South Auckland.
This weekend, CYF head Ray Smith issued a statement to the Herald on Sunday publicly apologising for allowing the abuse to happen to a child in the agency's care.
