As unbelievable as it sounds, there is no law preventing convicted sex offenders from working at schools, but the Teacher's Council can place strict conditions on teachers with such convictions.
The teacher, who has name suppression, pleaded guilty in the North Shore District Court in 2009 to eight charges of indecent assault on a 15-year-old girl. The offending occurred in 1991.
He is teaching girls of the same age but a court order prevents the school being identified.
The Teachers Council has put conditions on the man's employment but has refused to say what they are.
Those who led the inquiry found insufficient evidence to confirm the teacher was a risk to children but did recommend a review of legislation and policies on the amount of discretion available to schools.
In my view, given the level of trust placed in teachers, people with convictions for sex crimes should not be able to teach and it is hard to fathom how a school could consider it a good idea to employ someone who does.
Corrections Minister Anne Tolley says a complicated law change would be needed to make criminal background checks compulsory for all staff teaching in schools. Complicated or not, such a law change should be pushed through and those with convictions for sexual offending should be banned from teaching.
