WELLINGTON, Feb 8 - Education Minister Chris Hipkins on Thursday introduced a bill that will prevent any more charter schools opening, and said he would like to terminate the contracts of the 10 existing ones.

ACT leader David Seymour initiated charter schools under his party's support agreement with National.

"It's ideology over evidence and payoffs to union backers as the government seeks to massacre partnership schools despite their popularity and success," he said.

"Today's announcement shows the juvenile and callous nature of a government led by ex-student politicians."

Former education minister Nikki Kaye said charter schools were being treated disgracefully.

"How can these schools go into negotiations in good faith when they know the minister wishes them to close?" she said.

"It is also apparent that there is no transition plan for the children and young people who attend existing partnership schools." 

The Post-Primary Teachers Association hailed the announcement as a great day for students, teachers and parents.

"With the rest of the world turning against privatised, for-profit education New Zealand can lead the world with real investment and support for public education," said PPTA president Jack Boyle.
