A new report on the experiences of Māori children at school shows more must be done to make them feel comfortable and confident, says Kelvin Davis.
"It's heartbreaking to see some of the comments from tamariki and rangatahi around the attitudes and sense of isolation they can face," the associate education minister says.
"All children have the right to an education where they are not subjected to bias, low expectations and racism or other discrimination because of their culture, ethnicity or identity."
Mr Davis said he knew many schools were working hard on those issues.
"We have come a long way but we need to go further in our education system, and work collectively to create a culturally safe place that will make Maori students more comfortable, confident and successful."
The report is one of a series issued by the Commissioner for Children and the School Trustees Association.
