A Ngati Kahungunu hui in Hastings today is the first of three planned to update iwi members on negotiations with the Crown over water rights for Maori.
The powerful Iwi Leaders Group, made up of tribal leaders from around the country, has been in discussions with the Government over giving iwi more rights of water allocation.
Ngati Kahungungu Iwi Incorporated chairman and Iwi Leaders Group member Ngahiwi Tomoana said ongoing discussion had involved the group putting the case for a new water-management regime with stronger recognition of Maori rights to water.
"We say a good environment is good business and it's on that basis that we have made overtures at a national level to cabinet that there should be a stronger regime recognising our rights [to water]," he said.
"At the moment it's still first-past-the-post and grandparent rights from when water was first allocated. It's not sustainable.
