A former teacher from Auckland's exclusive St Kentigern College has been suspended, after she was caught at school with a bottle of vodka, and swore at a junior colleague.

The Teachers' Disciplinary Tribunal has today censured Rochelle Craig, the former head of dance at St Kentigern - and given her an 18 month suspension for serious misconduct.

Craig also had two drink-driving convictions - and another teacher reported seeing an alcohol bottle sticking out of her handbag.

Craig was brought before the tribunal after the school made a mandatory report in 2013, following her resignation due to health issues.
