A charter school system is set to be carried out in South Auckland and Christchurch on a trial basis.
The schools are effectively state-funded institutions without some of the rules and regulations other public schools have and, under the system, private companies are allowed to take over management of failing schools.
It is part of Act's confidence and supply agreement with National and has been implemented in a bid to raise achievement levels in poorer communities.
However Mr UNasa, who is also the chaplain at the University of Auckland, said the move would only make things worse for some schools in those areas.
It also inadvertently separated various communities - something that was unhealthy, he said.
Yesterday former Act president Catherine Isaac was appointed to lead the charter school trial.
Sole Act MP John Banks said although there had not been any community consultation beforehand, he promised there would be before the school system was implemented.
