ACT is aiming to win 5% of the party vote at the next election despite its dismal result last November when it won just 1%.
About 120 delegates at the party's annual conference in Auckland at the weekend were told they will have to put an end to the disunity that spoiled the previous three years.
The party leader and its only MP, John Banks, warned the delegates they had to put the divisions of the past behind them.
Party president Chris Simmons says disunity was part of the reason for last year's poor election result.
He says the party has to show it is united if it's to get more votes at the next election.
