People will be "marching in the streets" against local government amalgamation, says Napier's new MP Stuart Nash.
"We are going to mobilise the Labour machinery to make sure people understand the issues and understand the consequences," he said.
During his recent election campaign he was surprised by the high number of people offering to "get out and help" fight amalgamation.
"I think we will be able to galvanise Napier people to get out and support this in a way we haven't seen perhaps since the hospital on the hill closed."
He said he had talked with fellow anti-amalgamation group Dedicated and Democratic.
"We are going to combine our financial and human resources and you will see a very positive campaign run."
The Local Government Commission is due to release a revised amalgamation plan for Hawke's Bay's five councils, after reviewing submissions on last year's draft proposal.
A poll would be held on the proposal if 10 per cent of voters request it. If the majority of voters in the poll did not support amalgamation the proposed merger would not happen.
Hawke's Bay Today ran an unscientific poll on its website from Friday until yesterday asking people what they thought of amalgamation. Between 1600 and 1650 votes were cast. Fifty-eight per cent of those who voted were in favour of the amalgamation of Wairoa, Napier, Hastings, Central Hawke's Bay and the Hawke's Bay Regional Council.
Thirty seven per cent said they were against amalgamation of Hawke's Bay local authorities in any form, while 5 per cent believed only Napier and Hastings should be amalgamated.
Napier mayor Bill Dalton, who is a strong opponent of amalgamation, said he doubted the validity of the poll.
"Reality is nothing like that," he said.
"Your poll has been hacked - it is completely manipulated."
Hastings' mayor Lawrence Yule, who supports amalgamation, said he thought voting would be closer.
"It is promising," he said.
"There is only one poll that counts and, as I have always said, the arguments are either good enough for some change or the status quo will be there. The people of Hawke's Bay will decide."
Pro-amalgamation lobby group A Better Hawke's Bay chair Rebecca Turner said now the general election was over it was time to plan a campaign "ensuring the public is fully informed about why amalgamation would help this region".
"We need to be able to counter some of the misconceptions and fears out there," she said.
"We need to make sure people have full information as to why the region could benefit from amalgamation."
Mr Dalton said councils were not allowed to influence public opinion once the final proposal was out but there was "an enormous" number of people who would "fight the good fight".
