Prime Minister John Key has brushed off the threat the Waitangi Tribunal could derail the government's plans to sell off minority stakes in state-owned enterprises.
The Maori Council has been granted an urgent tribunal hearing over claims about Maori ownership of water, raising the possibility of the tribunal ruling out the sale of up to 49 per cent of hydro generators.
But Mr Key told reporters in Queenstown on Thursday the tribunal's rulings were not binding on the Crown.
"Previous governments have ignored their rulings in the past and this one might as well."
Mr Key did not believe it was a spanner in the works and said the council did not have overwhelming support from all Maori groups.
It was possible the sales could be halted somehow but the government would continue with the process as it believed it would benefit the country, he said.
North Island iwi Tuwharetoa has also launched a legal challenge to the sales.
Mr Key said the government would deal with challenges on their merits.
