The One News poll released last night showed National's Simon Bridges holding 48 percent support against Mr Peters' 28 percent.
Mr Peters is going to try to win back the seat in this year's election after losing it to National's Bob Clarkson in 2005.
"I think Winston will take the poll just as a motivation to get out there and work harder," Miss Clark said this morning on TV One's Breakfast programme.
"I guess he will be looking at his strategies, he probably won't read too much into that poll at this particular point."
Mr Peters lost Tauranga to Mr Clarkson by just 730 votes, but NZ First secured 5.7 percent of the party vote nationally which gave it seven MPs.
One of the advantages Mr Bridges has in this year's election is that he is able to spend much more time in the electorate than Mr Peters, who is foreign minister and is often out the country.
Miss Clark said that would make it harder for Mr Peters.
"On the other hand, he's a household name and brand," she said.
"People have written him off before and he's come back."
