Mr Craig, a self-made businessman, said he was confident his success in business would win him Asian support, adding that he had had good support from them during the Auckland mayoral campaign.
"I think this will carry through to the support they will give to the Conservatives."
The party will be fielding candidates in the 63 general electorates. It registered 1.1 per cent in the last Herald-DigiPoll survey.
Mr Craig said the party had concentrated "mainly in the rural areas" but would focus on Auckland in the next two weeks.
"Decisions about who people vote for get made quite late in the piece," he said. "A day is a long time in politics, and we've still got two and a half weeks."
Epsom candidate Mr Kan, who had a triple heart bypass two weeks ago, said he would be using "mathematical logic" to win votes.
"Vote for John Banks and you get at most two Act MPs into Parliament at Act's current polling, but the chances of National getting a stronger support party is higher with a double tick for the Conservatives," Mr Kan said.
Mr Young said Asian voter apathy was the biggest worry. "If we lose, it's not because we don't have Asian support, but because they didn't come out to vote."
