Labour party leader Andrew Little says water should not be traded as a commodity in New Zealand.
Mr Little, who spoke at Te Tii Marae at Waitangi today, told media after his official address mixed feedback from iwi and the Government over water ownership rights was a reflection of wider conflicting views on the issue.
"Certainly, local people and local iwi - they want water and they want access to water because they need it," Mr Little said.
"Whether or not it's about making a profit from it, some have that view clearly but others don't.
"I think...this is the big challenge we face as a country. There's a long way to go yet and this is an issue that all New Zealanders need to be debating.
