Iwi and tribal trusts are having their say on the future of freshwater on the East Coast.
Maori organisations are part of Gisborne District Council-run roopu set up to ensure there's enough supply to meet demand.
Estimates show the use of freshwater in irrigation alone will triple over the next 50 years.
Te Aitanga-a-Mahaki is a member of the Freshwater Advisory Group and tribe administrator Potatutatu Bill Ruru says his iwi's focus on is on the quality of water, after years of pollution.
Mr Ruru says he's been taken aback by the poor quality of water and is he's amazed by the degradation of water quality, which he blames on poor management.
Public feedback on plans for the future of freshwater closed on Friday but the Gisborne District Council says people can still have a say once a plan has been drafted.
