ACT was one of the big winners out of the latest political poll showing they would form a coalition with National.
According to the latest Roy Morgan Poll released last week, support for ACT was up 1.5 percent to 11 percent - its highest since February.
Support for a National and ACT coalition has dropped 2.5 percent to 46 percent but it is still higher than the current governing of Labour and Greens which is on 44.5 percent.
The gap between the two coalitions is the smallest since Christopher Luxon became National leader in November last year.
ACT leader David Seymour told AM Early on Wednesday the latest results show there will be a change in Government after next year's election.
"Look, the latest polls show the Government is going to change, ACT's going to be a big part of that new Government and that means that we're going to get real solutions to the cost of living that keeps rising, the crime that's out of control and this Government's constant attempts to divide us with co-government," Seymour told AM Early host Bernadine Oliver-Kerby.
National has come under fire this week after Tauranga MP Sam Uffindell was stood down from the party's caucus on Tuesday night pending an investigation into allegations of bullying behaviour in his younger years.
Seymour said he hoped if any ACT members were in the same situation they would come forward and tell the party.
"As the leader, I would hope that people within ACT would tell me things such as this that they knew were clearly important," Seymour said.
"It appears to have been a communication breakdown within the National Party, that's their problem. I just focus on making sure we don't have it within ACT.
"I certainly feel sorry for some of the National Party leadership who apparently didn't know, but on the other hand, they're leading a party that they didn't require to tell them."
