Both National and its leader Simon Bridges have taken a hit following the Jami-Lee Ross scandal.
It's been one of the roughest chapters in the party's history, and it's left them damaged and under the pump.

The latest 1NEWS Colmar Brunton poll shows Labour is now ahead of National in the eyes of the public.
It's up 3 percent to 45 percent, while National is down 2 percent to 43 percent. The Greens also saw a rise, up 1 percent to 7 percent, while there was no change for New Zealand First.
Simon Bridges' personal poll rating also took a tumble, falling 3 percent to just 7 percent - his lowest since he became leader. He's followed closely by Judith Collins, only 2 points behind on 5 percent.
Thirty-eight per cent of those polled said they felt less positive about Mr Bridges as a result of his handling of the Jami-Lee Ross saga. Only 2 percent said they felt more positive.
However despite the fall, Mr Bridges says he wouldn't have done anything differently and his leadership isn't under threat.
Meanwhile, Jacinda Ardern saw her ratings hit their highest point ever since she became Prime Minister, up to 42 percent.
These results put Labour ahead of National for the first time since February, and would deliver 68 seats to the Coalition Government based on current polling.
