Land and Water Forum cannot agree on formula but price may be put on water for farmers and others.
Farmers, industries and other large users may be charged for water under a new policy being developed, Finance Minister Bill English indicated yesterday.
Mr English said water reform may include "pricing" after the Land and Water Forum - a group made up of representatives from the farming, industrial and tourism sectors, conservation groups and iwi - said it could not reach agreement on the issue.
The forum, which has been working to hammer out consensus on how fresh water should be managed since 2009, produced its third and final report yesterday.
The report dealt specifically with how to allocate water and manage its quality.
