Judith Collins retires from politics

Senior National Minister Judith Collins has announced her retirement from politics.

Prime Minister Christopher Luxon on Wednesday confirmed Collins had been appointed President of the New Zealand Law Commission.

The Prime Minister's office confirmed Collins would remain an MP and continue to hold her portfolios until she moves to her new job in the middle of the year.

A spokesperson also confirmed her resignation would not automatically trigger a by-election for the Papakura electorate as it would be close enough to the general election.

First elected in 2002, Collins is the current longest continuously serving female MP, one of the most experienced politicians in the government, and has a reputation for toughness.

There were rumours of her departure over the summer break.

She preceded Christopher Luxon as National leader, taking the party to a resounding defeat in the 2020 election, which led to Labour taking enough seats to govern alone for the first time in MMP history.

The campaign was marked by accusations of racist separatism around the He Puapua report and increasing accusations of announcing policy on the hoof.

During an election debate with Labour's Jacinda Ardern, she was asked by Aorere College head girl Aigagalefili Fepulea'i Tapua'i about students having to quit school and find employment to support their families, and began with "My husband is Samoan so, talofa".

She was replaced in November the following year after suddenly demoting rival Simon Bridges in a late-night statement, accusing him of serious misconduct.

The handling of that led the party to a vote of no confidence in her, and her replacement, but under Luxon's leadership, she has reformed her image as one of the government's most effective ministers, now holding seven portfolios.

As Defence Minister this term, she has led a huge increase in spending and bolstered the Defence Force's equipment and property - and has fronted the handling of the Manawanui sinking.

She has also been minister for the spy agencies, the public service and digitising government, and in her former role as Science, Innovation and Technology Minister, led large-scale reforms to the sector.

Early in her political career, she earned the nickname "crusher" Collins for a policy that would see boy-racers' cars crushed if they were caught speeding.

Collins is no stranger to controversy. In 2014, in John Key's government, she was on her "final warning" after endorsing Oravida milk, which her husband is a director of.

She received her second final warning when her involvement in the Dirty Politics saga was revealed, and resigned her portfolios later in 2014 after accusations she undermined the head of the Serious Fraud Office as Police Minister, but returned to Cabinet in 2015.

After claiming no prisoners had escaped while she was Corrections Minister - soon corrected to 20 escapees - she explained the quote away as a joke, saying people could tell she was joking when her eyebrows went up and urging reporters questioning her to "bone up on your comedy skills".
