Hawke's Bay iwi Ngati Kahungunu wants to know how it might benefit financially from a proposed dam, without becoming an investor.
It's one of three iwi who have made an agreement with the regional council to talk about making changes to the Ruataniwha Dam plans.
Ngati Kahungunu runanga chair Ngahiwi Tomoana says discussions will take in to account the interest of the tribal people along the river.
The tribe has asked for all information on the dam so it can examine the data and reach its own conclusion on the benefits of any water storage scheme, he says.
The tribe will be holding hui with its people to find out their views on the Ruataniwha proposal.
