The Green Party says the Government should tell taxpayers how much its first school public private partnership contract is worth.
The Government says its contract with Learning Infrastructure Partners to build two schools in West Auckland is commercially sensitive.
But Green education spokesperson Catherine Delahunty says taxpayers have a right to know the details of the 25 year deal, and whether there will be any savings.
She says the Government is pushing this plan because it likes the idea of business having a role in controlling and owning public schools.
Labour MP Nanaia Mahuta also believes the public deserves to know what the contract is worth, but says she accepts there are aspects of the deal that would be commercially sensitive.
The Government says it expects to be able to release some of those contract details over the next few months.
The consortium will also maintain the buildings over the next 25 years.
Associate Education Minister Craig Foss told Morning Report that will free the schools and taxpayers from any ongoing costs associated with the projects.
