Bay of Plenty MP Todd Muller's tumultuous 53 days as Opposition Leader saw controversy, four National MP resignations, one resignation reversal and even a minor surgery.

May 26 - National's leadership team incorrectly described finance spokesperson Paul Goldsmith as Māori, after questions about the lack of Māori MPs in their top 12 line-up. Mr Muller also was forced to make a u-turn over his controversial Donald Trump "Make America Great Again" cap, saying it would be packed away in a box. Amy Adams reversed her decision to leave Parliament.
June 9 - Mr Muller underwent minor surgery to remove pre-cancerous moles.

June 27 - Anne Tolley announced her retirement at the election - despite previously indicating her intention to be Speaker should National win the election.
