Mr Dalton said the election was important because it was a time when people could have their say.
He said it would be nice if everyone got out and voted.
"If people vote then they feel engaged."
In the past, Napier's turnout has been higher than the New Zealand average.
In the last election it was 47.24 per cent, which is higher than the 2010 election when it was 44.88 per cent.
"Hopefully that's a trend that's continuing as more and more people engage with local government," Mr Dalton said.
An ongoing issue was that more affluent areas had the greatest voter turnout, the mayor said, with Ahuriri having the highest voter turnout last election, Taradale had the second highest and Tamatea and Nelson Park the third and fourth highest turnout.
