National has gone up and the coalition is still in a position to form a government - but only by the slimmest margin - according to a new poll.

The Taxpayers' Union Curia poll was released on Friday.

It shows the Opportunity Party has broken through the 5% threshold needed to enter Parliament, with 6.1%.

But it would form part of the Opposition after National ruled out working with it last week.

National is up 0.5 points to 31% - making it the most popular party in Parliament - while Labour has taken a decent drop of 3.7 points to 27.8%. 

The Greens are down ever so slightly to 10.1%, while New Zealand First also dropped, down 1.7 points to 9.1%.

ACT gained slightly to 7.3%,  while Te Pati Maori has recorded its worst result since March 2023 with just 1.5%, down 1.9 points.

The coalition parties - National, ACT and New Zealand First - would be able to form a government with 61 seats if this poll was replicated on election day.

The Opposition - including the Opportunity Party - would have just 59 seats - not enough to govern.

On this poll result Labour would lose five seats.

In the preferred Prime Minister polling, National's Christopher Luxon is ahead on 23.2% - up 4.1 points - compared to Labour leader Chris Hipkins, who is down slightly to 19.8%.

The poll surveyed 1000 respondents between Saturday and Tuesday and has a margin of error +/- 3.1%.

The general election will be held on November 7.
