Details of how a convicted sex offender was able to work in six North Island schools won't be made public yet, but the Government has received a report into the incident.
Te Rito Henry Miki was sentenced last month to more than four years in jail after he pleaded guilty to seven charges of using a fake CV and birth certificate to gain employment.
He was also convicted on four counts of breaching parole conditions which prevented him becoming a teacher or contacting children under 16.
News that the convicted sex offender had been able to gain teaching positions shocked the communities involved and Education Minister Hekia Parata called for a ministerial inquiry into the events.
She has received the report, by former ombudsman Mel Smith and Education Review Office boss Judith Aitken.
Fairfax Media understands it is critical, but details will not be released until relevant ministers have had a chance to consider it.
"This report will help us identify weaknesses in the system and what we need to do to address these," Parata said.
In the meantime, a review of the Teachers Council, the body that registers teachers, will begin. It is expected to be completed by September.
Miki evaded authorities for five years after his release from jail for an indecent assault on a 14-year-old boy, when he was supposed to be under an extended supervision order.
He used an alias to register and gain work as a teacher during that time.
Auditor-General Lyn Provost yesterday released a separate report into training, registering and appraising for teachers.
She said that improving teacher quality required the whole system to work well because of the interdependence of public entities involved.
