Mr Dalton said yesterday the 95 per cent awareness rating was "incredibly high" and meant Napier residents had taken the trouble to understand the issue.
"The Local Government Commission should sit up and take notice that it is abundantly clear that the people of Napier reject amalgamation," he said.
But Mr Yule said it was premature for the region to make up its mind on amalgamation because the Local Government Commission had yet to release a "final" proposal with full details on how the single super council would be structured.
After publishing its draft proposal late last year, the commission took submissions and held hearings this year where it was presented with suggested changes. Those included increasing the number of representatives on the single council, the ring-fencing of existing council debt and where the unitary authority's headquarters should be located.
"Once all those things have been dealt with, then I think a poll and an understanding is far more important than what people think now because in my view what the opponents are doing are scaring people with tactics around things that can easily be resolved and hopefully will be resolved in the final proposal," Mr Yule said.
"When people understand that the debt is not going to be paid for unfairly and when people understand the relative debt levels to asset bases and all the rest of it I think they may form a more informed view than what is currently the case where they're just being scared by erroneous data."
There was "only one poll that counts" - a vote expected to be held some time next year across the region to decide if the commission's final proposal, due to be released after next month's general election.
"That will be where people decide they either want the status quo or they want something different and there's a lot of water to flow under the bridge before we get to that point," Mr Yule said.
The process for that regionwide poll is also the subject of disagreement, with Mr Dalton among those to oppose a 2012 law change that means that amalgamation would become a reality if a majority of voters across all Hawke's Bay voted for it.
Under the previous law - and also under a policy change being promised by the Labour Party if it wins next month's general election - individual districts and cities would have the ability to veto amalgamation proposals affecting their areas.
The strong anti-amalgamation sentiment shown in the Napier City Council-commissioned survey made it "abundantly clear" why the pro-amalgamation National-led government had changed the law to scrap the veto provision, Mr Dalton said.
