A privacy breach by Child Youth and Family has resulted in the department taking legal action, claiming a woman was trying to blackmail them after it accidentally sent her somebody else's private information.
In a statement, CYF head Bernadine Mackenzie said the department had mistakenly sent a Family Court document to another person, who was refusing to return or destroy it.
"She is demanding that we return one of her children to her care in exchange for the document," Ms Mackenzie alleged.
Social Development Minister Paula Bennett said the mistake was disappointing and would be investigated, but appeared to be human error. The document was mistakenly sent with other material to the woman a few days ago. CYF realised their mistake and tried to get the document back, but the woman refused and allegedly said she would go to the media if the department did not return her child.
"It was personal information on a young person that certainly should not have been passed to someone else. A mistake has been made by the Department.
