Prime Minister John Key says he will review former Education Minister Anne Tolley's response to questions about a principal stood down for serious misconduct and later appointed as an "expert'' adviser for the ministry.
Deborah Anne Mutu was put on leave as principal at Te Kura Kaupapa Maori o Kaikohe in 2007 after her husband John Hone Mutu, a teacher at the school, was suspended by the board of trustees.
Mr Mutu was suspended after an incident in 2004, when he visited a 15-year-old student at home, knowing she would be alone.
While at the girl's house, Mr Mutu was found lying on a mattress with the girl, under a blanket.
Following the incident, Mrs Mutu ordered staff to tear up the written complaint of the girl and failed to launch an investigation into the allegations.
