Education Minister Hekia Parata believes a survey, which found some teachers negatively stereotyping Maori students, isn't reflective of what most teachers think.
The study called Teacher Expectations, Ethnicity and the Achievement Gap, has been written by Hana Turner.
Ms Parata said most teachers she knew of - worked very hard to help their Maori students to achieve.
She said it was a disappointing survey about how 15 teachers under-rated their Maori pupils - but they were only a small portion of teachers.
The minister said there were many learning strategies such as He Kakano and Te Kotahitanga which schools used to boost Maori success.
