Former National Party leader Todd Muller has revealed he will run at the next election despite announcing in June that he would retire.
It comes as the Bay of Plenty MP has been named as an unranked member of the Chris Luxon-led National Party caucus. Muller holds the oceans and fisheries and internal affairs portfolios.
Muller said he was comfortable with not being given a ranking.
"I genuinely have no concerns at all, as there is so much work to do, not only to prosecute this Government but continuing to build a clear vision of what we would do differently."
Muller also said ultimately he would do what was best for the National Party and his constituents.
"I'm excited and certainly feel reinvigorated. I have signalled to the Bay of Plenty electorate chairperson Mary Webster that I will put my name forward to stand again at the 2023 election."
Muller said he was "delighted and excited" with the portfolios he has been given, and to be able to continue to contribute to party successes.
"Oceans and fisheries is a pertinent portfolio for this country, particularly for this electorate [Bay of Plenty]," he said.
Asked about the party caucus, Muller said: "I think it's a great line-up, and you get a real sense of a National Party caucus chosen very much on performance, which is a good thing. People want to see a shadow cabinet of MPs who can run the future government."
Webster said she was excited for Muller given his decision to stand again and his portfolios.
"It's good for Todd and good for the Bay of Plenty electorate, and there is a lot of support for him to do so."
Webster also said that there was great support for Luxo, who had set a "clear sense of direction" for the party going forward.
In June, Muller announced he planned to retire at the next election after nine years as the MP for the Bay of Plenty.
Muller was first elected to Parliament in 2014 as the MP for Bay of Plenty, a seat he won again in 2017.
On May 22 last year, an election year, Muller ousted Tauranga MP Simon Bridges to become National Party leader.
Just 53 days later, Muller made the shock announcement that he was stepping down from the role for health reasons.
Since then he has opened up about his mental health battles, particularly with anxiety and panic attacks.
In June this year Muller was pushed to announce his retirement following a confrontation with then-leader Judith Collins.
The announcement followed a late-night caucus meeting in which Muller admitted he was one of several unnamed MPs criticising returning MP Harete Hipango in a media article.
Muller confirmed to the Herald he admitted at that caucus meeting to making a comment that was quoted in the media.
"I did not leak," he said at the time. "I made a comment to a journalist that was subsequently quoted. Yesterday I admitted to that and apologised for this."
He would not comment further on whether that was a factor in his resignation, or whether Collins had demanded he resign.
Collins was understood to be furious about Muller's admission.
Bridges is ranked third in the National Party caucus and holds the finance and infrastructure portfolios.
Meanwhile, Rotorua MP Todd McClay has fallen from number six to unranked in the new caucus. He has the trade portfolio and tourism.
McClay says he isn't bothered after he was announced as an unranked member of the National Party caucus.
He was "very pleased" with his two portfolios, particularly having the trade portfolio as he was a former Trade Minister, and also previously was the Associate Minister of Tourism for about three years.
He was also looking forward to working alongside Muller who was a "really experienced and capable MP".
McClay said the Government had let the tourism industry down especially in the Rotorua electorate and National Party leader Chris Luxon has given him free rein to focus on holding the Government to account.
McClay said the reshuffled caucus was a "great lineup" and Luxon had matched MP's abilities with portfolios.
One of the biggest losers of the reshuffle is Collins, demoted to 19th. But she still stays in the shadow cabinet and has the research, science and innovation portfolio.
Luxon decided to part with the tradition of giving the entire caucus - except new and departing MPs - a numbered ranking. Instead, he's given rankings to the first 20 MPs and left the rest unranked.
'Ultimate team sport'
Speaking at a press conference after revealing the reshuffle this afternoon, Luxon described politics as the "ultimate team sport".
He said his line-up was based on performance, as well as matching people to their experience and skills.
Luxon said every MP had a significant role to play, and he hadn't ranked those below the shadow Cabinet because it was irrelevant, and performance mattered more than ranking.
The new party leader said he'd spoken to every MP himself but had not talked to previous leaders Sir John Key, Bill English or Steven Joyce to get their opinions on MPs' strengths and weaknesses.
He confirmed that Muller had re-entered the caucus.
This afternoon Luxon said he watched the MPs closely for the past year and saw where their strengths and weaknesses lay.
He said he had watched low-ranked MPs perform very well against their counterparts in that area.
