Much of that dramatic jump was down to the "rally-around-the-flag" effect, whereby the Government gets a major bump in the polls after a national tragedy or disaster.
It happened with National after the Christchurch earthquake.
In fact, Ardern might have been breathing a sigh of relief in her ninth-floor Beehive office after seeing the numbers tonight.
The poll was taken between last Saturday and Wednesday this week – meaning it captured the full fallout of the Government's border blunders.
That saga has consumed the political narrative this week and the Government risked losing much of the goodwill it garnered throughout the lockdown.
It could have been a lot worse than 9 per cent for Labour.
Despite the drop, on these numbers Labour would be able to govern alone. Ardern wouldn't need the Greens and, more importantly, she would not need Winston Peters' New Zealand First.
