Allowing tertiary institutions to run charter schools is being considered.
Five of the schools opened this year and Education Minister Hekia Parata is in negotiation with those hoping to open more next year.
The publicly-funded but privately-run schools are bitterly opposed by education unions and have become an election issue with Labour, the Greens, NZ First and Internet-Mana promising to scrap them.
The Ministry of Education in April gave Ms Parata a report titled "Tertiary Education Institutions as Sponsors of Partnership Schools". The next month another report was produced.
