"This session is very much about identifying the outstanding values on the Ngaruroro River," Carlyon said. "Think of it as like a 'water national park'. We've got 15 in New Zealand already and this will be the 16th.
"It doesn't mean - in the way people think about national parks - that you take that special place and just lock it up. You just move it to a place of maturity, where you can still live and breathe, work and play."
Carlyon highlighted the "outstanding values" of the Ngaruroro and Clive rivers, some of which included the water quality, fish and bird habitat, rainbow trout fishery and whitewater rafting and kayaking.
The considerations of the WCO effectively planned to retain the quality, quantity and level of rate and flow, prevent any damming and prevent any direct discharges to water.
"When it comes to the lower Ngaruroro river and the Clive river the water quality is not that grand, the landscape is not outstanding, fish numbers are reasonably low."
Forest & Bird regional manager for Hawkes Bay Tom Kay said the point of the session was to "clarify issues with anyone who's unsure about what a water conservation order means, and to hopefully clear up some of the misinformation that has been circulating".
The session was well received by those who attended, with one member of the public saying the information put forward was "a lot more considerate and pragmatic than in the past".
