Muller did not directly answer the question, and when Woodhouse admitted on Friday that Boag had been an informant of his, it made Muller look like he hadn’t been honest with the public.

A few days later, Muller stood down as leader. 

“I think the matter has now been resolved and Michael supports that decision,” Collins said. [Woodhouse] fully understands it and he is very pleased with his new portfolios.

“This is a matter that needed to be dealt with. I think the public was rightly appalled people’s personal, medical records were being sent around or sent to MPs and they are rightly appalled that any of those fell into the hands of the media.”

Praise for Dr Shane Reti

Collins praised Dr Reti as the new health spokesperson Dr Reti. 

“We have in Dr Shane Reti someone who is not only a medical doctor, a specialist, and someone who has even worked at Harvard.”

Woodhouse and Dr Reti’s rankings are unknown until Collins unveils her reshuffle on Thursday.

Dr Reti was promoted earlier this month in Muller’s reshuffle. He was given the number 13 spot after former deputy leader Paula Bennett announced her resignation. 

Just days into his leadership in May, Muller came under fire for the lack of diversity in his shadow Cabinet line-up because there were no Māori MPs on the front bench or of any other ethnicity.

It came after the former leadership team of Bridges and Bennett – both Māori – were rolled by Muller and his deputy Nikki Kaye, who are both Pākehā.
