Prime Minister Jacinda Ardern is keeping a lid on any excitement, despite the latest Newshub polls which shows Labour on a strong 61 per cent, while National are down on 25 per cent.

The Prime Minister told Mike Hosking she always keeps a "healthy skepticism around polls".

"I'd like to feel like the general direction of them, the trend of them though speaks to a general confidence in the public around the Government's response to Covid-19 and our recovery plan," she adds.

Ms Ardern says there is a correlation with what they are seeing with internal polls, which shows a gap between them and National.

But she and her party are not getting ahead of themselves.

"We will never be complacent, a lot can change very quickly. We know that we have to continue everyday to earn the support of New Zealanders."

Meanwhile, the Prime Minister is confident they will get to the bottom of accusations surrounding Iain Lees-Galloway.

There is currently a ministerial investigation into whether the former Labour MP misused taxpayer money.

Ms Ardern says Mr Lees-Galloway left himself open to those accusations, but has assured her no money was spent inappropriately, and it will not take long to get to the bottom of this.
