Mr Bridges told the Bay of Plenty Times Weekend the survey was pleasing but the only poll that mattered was the one on election day.
"What people are appreciating more and more is that under MMP, elections are always close and the election is still up for grabs."
Mr Bridges said he was working hard to be returned as the Tauranga electorate MP but the party vote was the most important.
"I've certainly tried to run a high-energy campaign since the last poll."
Mr Mitchell said he did not think polls were a true indication of what would happen on election day.
"There's a groundswell for NZ First support and I'm looking forward to September 20.
"I think there is some real concern in the community at the moment and I feel that National haven't been listening to the people like they should have and could have been, and certainly not representing the people or the community as well as they should have been."
Mr Mitchell said he expected NZ First to hit double figures this election.
Greens candidate Ian McLean said the result was "very cool", especially with all the "silliness" going on in the political world at the moment.
He said he had lost a lot of his personal support in the Tauranga electorate with boundary changes so it was nice to see he was still garnering some support.
Dr McLean thought it was possible the Greens' refusal to get involved in the Dirty Politics saga could be a reason for improved party support.
Labour's Dr Jones said the results were disappointing but as the survey was non-scientific, she would just "roll with the punches".
"It doesn't feel like it's that bad out there," she said. "For us, out there we're still getting a real sense of a need for change."
Dr Jones said it was good there were a lot of undecided voters because that meant people were considering their choice.
ACT candidate Stuart Pedersen said the survey did not surprise him, although polling by the party showed about 10 to 15 per cent of Tauranga residents would agree with ACT's policies.
New Zealand Independent Coalition candidate Michael O'Neill said his team was working hard to get its message across about change and he was getting "good traction out there", although he felt people tended to stick with the status quo.
Independent candidates Rusty Kane and Yvette Lamare both said they would like to increase their presence in Tauranga.
United Future candidate James Maxwell said the polling showed the difference in campaign spending between the parties.
Conservative Party candidate Nathaniel Heslop and Maori Party candidate Verna Ohia-Gate did not comment in time for this edition.
