The four remaining charter schools which opened in 2014 have all been paid a performance bonus despite three not meeting their targets.
Documents released to the Labour Party under the Official Information Act show that Education Minister Hekia Parata approved the payments - 1 per cent of the school's budget - on advice from the Education Ministry and Charter School Authorisation Board.
The payments total around $60,000 and were made to Vanguard Military School, Terenga Paraoa, the Rise UP Academy and South Auckland Middle School.
The school at Whangaruru did not receive a payment, as it was closed down for performance reasons.
Labour education spokesman Chris Hipkins said only two out of four of the schools met their contracted targets, while another one had a compliance issue.
