Oranga Tamariki's privacy standards are in the spotlight after a critical review.
The report highlighted nine cases it described as a 'snapshot of issues'.
They include a locked cabinet of client files being donated to charity, and social workers giving a mother's and child's address to a father accused of rape.
In another, a mother suffered more abuse - after her file was shared with her child's father.
Minister for Children Karen Chhour says that case was particularly tough reading.
"That gives me grave concern - which is why I set an expectation for Oranga Tamariki around privacy and privacy breaches. These are unacceptable."
