Support for the Labour Party has taken a hit while the ACT Party, and its leader, is growing in popularity, new political polls show.

The latest Newshub Reid Research poll has Labour down 9.7 points to 43 per cent, while the National Party is up 1.7 points to 28.7 per cent.

The ACT party scored its highest ever Reid-Research rating over the weekend, up 4.2 points to 11.1 per cent of the vote.

A poll conducted in the Coromandel shows a similar trend.

Coromandel's CFM conducted the poll on Facebook over seven days last month.

Both Labour and National lost ground in the poll that looked at party support on the Coromandel.

On election night 2020, Labour had the highest Coromandel party vote with 42.31 per cent, National followed with 32.5 per cent, ACT was third with 9.62 per cent and the Green Party came in fourth position with 5.58 per cent.

The Coromandel CFM poll shows support for Labour plummeting to 25.1 per cent, equal with National.

ACT was the major winner with 26.2 per cent. The Green party also increased their share to 7.3 per cent in the Coromandel region.

'The race is long, there are 26 months to the election, but obviously we're grateful for this boost from the Coromandel,” says ACT leader David Seymour.

'It encourages us to work harder to be the region's representatives next election.”

Coromandel National MP Scott Simpson says polls are all very volatile at present and with two years to go before the next election, people will be perhaps a little freer with their views.

He says self-selected polls like the Coromandel poll aren't scientific, but were valuable to him as a local MP.

He feels the dramatic shift indicated away from Labour is due to unpopular recent decisions based on political ideology.

According to the Newshub poll, Prime Minister Jacinda Ardern is still a clear lead in the preferred prime minister rankings - down 2.6 points to 45.5 per cent - but Seymour has now passed Judith Collins.

The Reid-Research poll has Seymour in second place for preferred prime minister - up 3 points to 8.6 per cent with Collins a whisker behind at 8.2 per cent.

Collins says she's not concerned.

"No, it makes no difference at all. The fact is, is that the National Party's around three times the size of ACT, that's the way it normally works,” says Collins.

'That's just silly stuff coming out of Newshub. I also well remember the days when Winston Peters was significantly more popular as prime minister than Jim Bolger. It just doesn't work like that."
