The Te Kotahitanga teacher training programme will be rolled out to another 20 schools, thanks to the allocation of an extra $17 million in the Budget.
The programme helps teachers to work with and assess Maori students.
Waikato University education professor Russell Bishop says the money, spread over four years, will boost participation.
"What we're looking for is enough schools to reform the education they're providing for Maori children so that you can change the statistics of disparity that are existing in New Zealand today," he told Waatea News.
Professor Bishop says research is showing that Maori students in Te Kotahitanga schools are performing better in external exams than those at other schools.
