It would need support from the Greens, which were on 7 percent – also up one point.
New Zealand First are at 1 per cent – well below the 5 per cent threshold.
In fact, NZ First are now on the same level of support as the New Conservative Party, The Opportunities Party, the Māori Party and Advance New Zealand.
Some 11 per cent of voters don't know who they will vote for, according to Colmar Brunton - that's down three points compared to last week.
Tonight's numbers are the lowest in 10 years for New Zealand First.
On the preferred Prime Minister rankings, Jacinda Ardern is still well on top at 54 per cent. National leader Judith Collins is at 23 - which is the highest level of support for a National leader since Bill English.
Collins told 1News that her party was "chipping away and we're keeping on going".
"I think it's important to have the momentum," she said.
Collins said National's and Act's rise was a reflection on what people were thinking.
"Our poll result went up, so did [Act's] – it shows you that more people are sitting there and thinking about the economy."
Meanwhile, Ardern said: "The really strong sense I get from people is right now they are looking for strong, stable leadership in these times," she told 1News.
"Now is the time for that stable Government."
