Mr Banks said charter schools would allow flexibility in the way schools operate, allowing them to focus on disadvantaged children.
"We have a long tail of underachievement in New Zealand and that failure is institutionalised and inter-generational.''
Head of the authorisation board, Catherine Isaac, said the number of schools that were set up would depend on the quality and calibre of the applications.
She told Radio New Zealand existing schools were too restrictive.
"Some of the restrictions that I think are an issue for many schools are the fact that the resources have to used in a particular way - how you use resources is prescribed, the hours that you teach, the school year.
"For those that are trying to do something a little bit difference they are very constraining,'' Ms Isaac said.
She would not comment on individual applications.
Ms Parata echoed Mr Banks saying charter schools would allow for an education system that worked for all.
Yesterday in Parliament Opposition MPs asked whether the minister would rule out using schools earmarked for closure in Christchurch to set up charter schools.
Official documents obtained by the Green Party showed the first charter schools were likely to be established on the site of closed state schools or be private schools converted to charter schools.
Green Party co-leader Metiria Turei said closing a state school with 100 per cent qualified teachers and replacing it on that site with a charter school was "an insult to children and teachers who have fought hard to keep their schools open''.
Charter schools will not have to employ registered teachers or follow the national curriculum and will be exempt from the Official Information Act.
