A national Maori hui on water rights called by the Maori King is not expected to produce a resolution, but there's hope it will bring tribal unity over the issue.
The summit for iwi and hapu to talk about water is being held at Turangawaewae Marae in Ngaruawahia on Thursday.
It's been sparked by the Government only wanting to talk to iwi around the Waikato River.
Those particular iwi are directly affected by the Crown's plan to sell shares in Mighty River Power from March next year.
Ngati Tahu Ngati Whaoa deputy chair Roger Pikia says the hui will be a chance to hear what other tribes think about water.
He does not think the meeting will aim to resolve any matters about whether Maori are seeking ownership of water.
However, Mr Pikia, said it will simply work towards setting out key principles that will be agreed upon by all iwi throughout the country.
People from almost all tribes throughout the country are expected to attend the hui.
