New Zealand First got just 3.8 percent of the party vote in the latest Newshub-Reid Research poll, well below the 5 percent threshold needed to gain a place in Parliament.
That's mostly due to the popularity of Labour, which has risen 5.4 percentage points to 42 percent of the party vote. National's party vote has barely shifted.
Winston Peters, Deputy Prime Minister did not want to take questions on the poll result on Wednesday.
"We make a joke of your poll every single election," Mr Peters said as he avoided questions on his way to Question Time.
But that's not quite right. The final pre-election Newshub poll had New Zealand First on 7.1 percent. Its General Election result was 7.2 percent.
New Zealand First has been around for eight elections - 25 years - but on 3.8 percent, it won't be back.
The public has ditched Mr Peters before. In 1999, after the coalition with National fell apart, New Zealand First's vote dropped below 5 percent. Mr Peters only made it back into Parliament by winning the Tauranga electorate seat.
In 2008, Mr Peters became embroiled in a donations scandal involving Owen Glenn. The public gave him a firm "no" and voted his party out for a term.
But Prime Minister Jacinda Ardern continues to back Mr Peters, citing his personal popularity - 5.7 percent of those polled chose Mr Peters as their preferred Prime Minister.
Ms Ardern is a problem for Mr Peters. Since he put her in power, Labour has gobbled up New Zealand First's vote.
After losing so much support to Labour, New Zealand First may look to its regional development plans to lure more voters - particularly from provincial New Zealand.
If that happens, National's heartland could become key to the survival of Mr Peters' party.
How Newshub's polls work
Newshub-Reid Research interviews were conducted using online polling and computer-assisted telephone interviewing. Some 750 people were interviewed by phone and 250 online between Thursday, January 18 and Sunday, January 28.
Data is weighted to ensure a cross-section of representation of age, gender and geography.
The sample error is maximum of +/-3.1 percent at a 95 percent confidence level.
