Research has been launched into finding the best ways to teach students in Maori immersion schools.
The data is being collated by Nga Putanga, an arm of Te Runanga Nui o Nga Kura Kaupapa o Aotearoa - the national body that oversees kura.
One of its directors, Rawiri Wright, says kura implement the principles of Te Aho Matua in their own ways and the research group wants to investigate the range in which kura operate under the principles.
The five principles include te reo (language) and ahuatanga ako (education environment).
Nga Putanga expects to start writing up the feedback from about 60 schools. Once formulated, Mr Wright says the information could be useful for other kura.
The Government reserved $3 million in 2011 to support the national body to develop a curriculum and other resources. This will also be used to cover the cost of the research.
