IHC says there needs to be an accountability mechanism to resolve a situation that's unsafe for a child in school.

Education Minister Hekia Parata has confirmed controversial seclusion rooms will be banned in schools.

Trish Grant, advocacy director for IHC, a charity that advocates for the rights and welfare of people with intellectual disabilities, said it's taken several months from the initial complaint to action being taken, and that's a long time a child is spending in an unsafe situation.

"A parent makes a complaint to a principal, then they have to go to the Board, and then they might go to the Ministry. All those three steps have taken a long time.

"This is a long time in a child's life when things are very safe and not okay."

She said it's just one example of schools and the Ministry of Education not taking accountability.

Meanwhile, the bid to outlaw seclusion rooms in schools is getting strong support from the Maori Party.

Party co-leader Marama Fox said teachers still have the option to use time-out rooms.

"That is not locked up with a child in those rooms for vast lengths of time," she said.
