A former National Party President admits things don't look good for Simon Bridges.
His rating as preferred Prime Minister has plunged to 4.5 percent in the latest Newshub Reid Research poll, and his party's popularity has fallen to 30.6 percent.
As preferred PM, Ardern was at 59.5 per cent - up 20.8 points on the last poll, while Labour hit 56.5 per cent.
Michelle Boag says it's no surprise people have responded positively to the Prime Minister - whose ratings shot up to almost 60 percent.
She told Chris Lynch Arden's been visible everywhere during the pandemic and Bridges hasn't.
"There is no doubt there's a good chance of him becoming yet another victim of Covid-19."
Earlier, Bridges told Mike Hosking he was not letting the poll affect him.
"I'm the leader and I'm staying."
She says that will be up to the Caucus to decide the leader's fate.
If the results were reflected in the election, National's caucus would be decimated – it would lose 13 MPs. That would mean all but two of its List MPs if it held its current electorate seats.
