Candidate Moira Irving, who openly supports the Dam, said it has strongly impacted her campaign, particularly with regards to her use of social media.
"There have been some very unpleasant comments and some of my signs were defaced with strong comments that focused on my view of the Dam."
She said she had tried to emphasise to the people that there were many other issues that needed to be taken care of, not just the Dam.
"I am confident that Napier voters will be wanting councillors who do not have a single-issue focus, and I believe I have the experience and balance needed to be a good representative for Napier."
Candidate Martin Williams had also tried to focus on other issues but said being the lawyer for HBRIC made it difficult, as people assumed his position on the Dam before he could speak.
"I just wanted to correct everyone's misconceptions about the negatives of the Dam, as they can say it is not a good idea without knowing the actual risks."
Fifth-time campaigner Neil Kirton was also faced with the Dam question regularly and because he could not give a certain position, he said people who would normally support him were not planning to.
"This is the first time I am really unsure as to how it will go, it all depends on the opinion patterns of the people, whether they're pro Dam or anti Dam."
Alan Dick who is the only one going for another term, said he had been open with his policies and would find out on Saturday whether his position towards the Dam has had an affect.
"There are plenty of different views and opinions and I think Greenpeace have been dishonest in their approach but it is a democracy, so people will make their choices depending on their personal values."
He said he was not losing any sleep over the election but would be happy to see it over this weekend.
"It is in the lap of the Gods, at the end of the day it is up to the people."
