The government has received a ministerial inquiry report into how a convicted sex offender was able to dupe six schools into employing him as a teacher.
Education Minister Hekia Parata says the report will help identify weaknesses in the system that have to be addressed.
She's deciding how much of it can be made public.
Henry Te Rito Miki used false identities to apply for jobs as a teacher, breaching an order that he must stay away from children because of a previous conviction for indecent assault on his 14-year-old nephew.
He was last month sentenced to four years, one month and two weeks in jail after pleading guilty to charges of using a fake CV and birth certificate to get jobs as a teacher in six North Island schools.
Ms Parata ordered the inquiry in February after he was arrested.
It was conducted by former ombudsman Mel Smith and former Education Review Office chief executive Judith Aitken.
