Te Kohanga Reo Trust Board says it has been granted an urgent hearing by the Waitangi Tribunal.
The Kohanga Reo movement movement runs language nests for pre-school children.
The board says the Crown is failing to protect the schools and staged a hikoi to Parliament to deliver their claim to the Tribunal in July.
Earlier this week, the board said the Government had disputed its call for an urgent hearing, but the claim will be heard next week.
Kohanga Reo trustee Dame Iritana Te Rangi Tawhiwhirangi says the claim needs to be heard because the Government has given no guarantee Kohanga will not be affected by proposed changes to early childhood education.
