Support for the Act Party has jumped since Don Brash took over as leader, a new poll has revealed.
The Horizon Poll also showed the Mana Party has more support than the Maori Party.
Hone Harawira's Mana Party is at 2.3 per cent, while the Maori Party's lags behind at 2.1 per cent.
A third of the Mana Party's support is from those who voted for the Maori Party in the 2008 election.
Meanwhile, support for ACT is at 5.3 per cent, up from 3.7 per cent in April.
Brash said it was a pleasing start but there was a long way to go if his party wanted to make a difference in Parliament.
He believed some of the gain could be attributed to an open letter sent to Prime Minister John Key last week criticising him for his lack of courage.
"Most people have been tempted to vote Act have been beginning to feel more optimistic about the future," Brash said.
Labour made the biggest gain in the poll, showing it's support is up by 3 per cent to 26.9 per cent.
The number of undecided voters has also dropped dramatically from 8.4 per cent to 4.9 per cent.
The surveyed 1,845 people last week and had a margin of error of 2.3 per cent.
