Tensions within the Hawke's Bay Regional Council came to a head at a meeting of the Regional Planning Committee, when a councillor walk-out left the council unable to vote on an important issue.
The vote was to decide whether new minimum flow levels should be put in place for the Tukituki catchment, or delayed another two years.
Councillor Fenton Wilson, who supports delaying the new minimum flows, walked out, meaning the committee did not have a quorum and could not vote on the issue on Wednesday.
He said water security was vital to people, whether it was for personal or business use.
"Reluctantly, I am going to bring this to a head and remove the quorum, and we will have our deferral and we'll talk about it next meeting," he said before leaving the room.
