The plan to sell state-owned assets will face another hurdle today in the Wellington High Court.
The Government intends to remove Mighty River Power from the State-Owned Enterprises Act so it can sell up to 49 percent of the company.
But the Maori Council says that's an unlawful move on the part of the Government, because it says Maori have rights to fresh water. Despite the Waitangi Tribunal upholding the claim, the Government has forged ahead.
The Crown will argue that the privatisation of state-owned assets won't affect its ability to address the water rights issue.
Governor-General Sir Jerry Mateparae is then expected to sign an order-in-council this afternoon which officially begins the process to partially privatise the company.
The legal action by the Council today essentially aims to buy time for a judicial review of the entire process.
