Todd Muller came out on top as the new National Party leader on May 22. A little over a week later, things have not been oh so pretty for the Bay of Plenty MP.

From the 'Make America Great Again' hat drama, to claims of a lack of ethnic diversity in his Shadow Cabinet, has not done him many favours.

Muller and his party released their first policy to counter the effects of the Covid-19 pandemic on the country on Friday.

New Zealand Herald political reporter Jason Walls says it was a roller coaster week for Muller.

He says after a strong opening speech things gradually went down hill.
