The Government plans to review the Maori Language Act and all sectors which receive state funding to promote, teach and develop Te Reo.
About $226 million per year is spent on promoting the language.
The Government plans to review areas such as the Maori education sector, the Maori Broadcasting Agency, and funding for Iwi and hapu.
Maori Affairs Minister Pita Sharples says they want to ensure the money is being spent effectively. The review will also include a look at the act itself.
Meanwhile, Maori lawyer Annette Sykes says Te Reo should be used in all government departments, if it is to survive.
