All staff in charter schools will have to undergo rigorous police screening, parliament has been told.
The new charter schools - two are due to open in 2014 - don't have to employ registered teachers and opposition parties want to know how the government will guarantee sex offenders don't get jobs.
An inquiry report on how convicted child sex offender Te Rito Henry Miki was able to work in six schools before being found out and arrested was released on Tuesday.
It recommends 36 changes to teacher registration and screening regimes, and the government says it will adopt all of them.
Labour and the Greens say staff hired by charter schools who aren't registered teachers could slip through but Education Minister Hekia Parata says they won't.
"Every person in every partnership (charter) school will undergo extensive background and police checks," she said.
"That includes all non-teaching and teaching, unregistered and registered employees."
Ms Parata says about 25 of the 36 recommendations will be written into the contracts the government signs with schools.
Charter schools - the government calls them partnership schools - will be government funded but run by community or business organisations, and will be able to set their own curriculums, their own school hours and terms, and not all their teachers have to be registered.
