But Ms Rankin told the NZ Herald the party was realistic enough to know Mr MacIntyre was not expected to win.
"We don't have any illusions about that. But we didn't want to leave the seat vacant," she said. "We haven't got a party organisation there and didn't have a local candidate. Kim standing there gives the people a name and the party some visibility."
The Conservatives got a fillip on Wednesday with a 3 News/Reid Research poll lifting it close to the 5 per cent threshold it needs to get into Parliament.
The party surged to 4.6 per cent - up more than 2 points - with Mr Craig telling Radio NZ that the rise was coming from grassroot support in the regions.
He said the party was "hunting down" the 5 per cent party vote and believed it would achieve the goal.
The poll had NZ First up 1.7 points to 6.3 per cent, while support for National Party dropped by 2.5 points to 45 per cent, with Labour taking another hit, falling 2.6 points to 26.4 per cent. The Green Party got 13.5 per cent support, while Internet Mana had 2.1 per cent.
The survey, which polled 1000 people, had a margin of error of plus or minus 3.1 per cent.
