Education officials warned their minister at least three times that a charter school trust - now accused of bribing kids with takeaways - was not experienced enough to teach Maori children.
Education Minister Hekia Parata went on to grant the Villa Education Trust contracts for two schools, with the second now subject to a ministry investigation following complaints.
Parents and teachers wrote letters saying the Middle School West Auckland, in Henderson, lacked leadership, used food to manage behaviour, and that there was bullying, drugs, and a lack of cultural awareness.
In one case, children were offered fried chicken as a reward, teachers said.
Parents believed the school had resorted to using food as it did not understand their children as Maori or Pasifika. Some regretted enrolling their children in the school.
