Ardern became a list MP in 2008, a position she held for almost ten years until her election to the Mount Albert electorate in the 2017 by-election, held on 25 February. She was unanimously elected as Deputy Leader of the Labour Party on 1 March 2017, following the resignation of Annette King. Ardern became Leader of the Labour Party on 1 August 2017, after Andrew Little resigned from the position following a historically low poll result for the party. She is credited with increasing her party's rating in opinion polls. In the general election of 23 September 2017, the Labour Party won 46 seats (a net gain of 14), putting it behind the National Party, which won 56 seats. After negotiations with National and Labour, the New Zealand First party chose to enter into a minority coalition government with Labour, supported by the Greens, with Ardern as Prime Minister.
Ardern was brought into politics by her aunt, Marie Ardern, a longstanding member of the Labour Party, who recruited the teenaged Ardern to help her with campaigning for New Plymouth MP Harry Duynhoven during his re-election campaign at the 1999 general election.
Ardern joined the Labour Party at the age of 17, and became a senior figure in the Young Labour sector of the party. After graduating from university, she spent time working in the offices of Phil Goff and of Helen Clark as a researcher. After a period of time volunteering at a soup kitchen in New York City, Ardern moved to London to work as a senior policy adviser in an 80-person policy unit of then-British prime minister Tony Blair. She did not meet Blair in London, but did question him about the invasion of Iraq at an event in New Zealand in 2011. Ardern was also seconded to the Home Office to help with a review of policing in England and Wales.
Ahead of the 2008 election, Ardern was ranked 20th on Labour's party list. This was a very high placement for someone who was not already a sitting MP, and virtually assured her of a seat in Parliament. Accordingly, Ardern returned from London to campaign full-time. She also became Labour's candidate for the safe National electorate of Waikato. Ardern was unsuccessful in the electorate vote, but her high placement on Labour's party list allowed her to enter Parliament as a list MP. Upon election, she became the youngest sitting MP in Parliament, succeeding fellow Labour MP Darren Hughes, and remained the youngest MP until the election of Gareth Hughes on 11 February 2010.
Opposition leader Phil Goff promoted Ardern to the front bench, naming her Labour's spokesperson for Youth Affairs and as associate spokesperson for Justice (Youth Affairs).
She has made regular appearances on TVNZ's Breakfast programme as part of the "Young Guns" feature, in which she appeared alongside National MP (and future National leader) Simon Bridges.
Ardern contested the seat of Auckland Central for Labour in the 2011 general election, standing against incumbent National MP Nikki Kaye for National and Greens candidate Denise Roche. Despite targeting Green voters to vote strategically for her, she lost to Kaye by 717 votes. However, she returned to Parliament via the party list, on which she was ranked 13th. Ardern maintained an office within the electorate while she was a list MP based in Auckland Central.
After Goff resigned from the Party leadership following his defeat at the 2011 election, Ardern supported David Shearer over David Cunliffe. She was elevated to the fourth-ranking position in the Shadow Cabinet on 19 December 2011, becoming a spokesperson for social development under new leader David Shearer.
Ardern stood again in Auckland Central at the 2014 general election. She again finished second though increased her own vote and reduced Kaye's majority from 717 to 600. Ranked 5th on Labour's list Ardern was still returned to Parliament where she became Shadow spokesperson for Justice, Children, Small Business, and Arts & Culture under new leader Andrew Little.
Ardern put forward her name for the Labour nomination for the Mount Albert by-election to be held in February 2017 following the resignation of David Shearer on 8 December 2016. When nominations for the Labour Party closed on 12 January 2017, Ardern was the only nominee and was selected unopposed. On 21 January, Ardern participated in the 2017 Women's March, a worldwide protest in opposition to Donald Trump, the newly inaugurated President of the United States. She was confirmed as Labour's candidate at a meeting on 22 January. Ardern won a landslide victory, gaining 77 per cent of votes cast in the preliminary results.
Deputy leader of the Labour Party
Following her win in the by-election, Ardern was unanimously elected as deputy leader of the Labour Party on 7 March 2017, following the resignation of Annette King who was intending to retire at the next election. Ardern's vacant list seat was taken by Raymond Huo.
On 1 August 2017, just seven weeks before the 2017 general election, she assumed the position of leader of the Labour Party, and consequently became Leader of the Opposition, following the resignation of Andrew Little. Little stood down due to the party's historically low polling. Ardern was unanimously confirmed in an election to choose a new leader at a caucus meeting the same day. At 37, Ardern became the youngest leader of the Labour Party in its history. She is also the second female leader of the party after Helen Clark. According to Ardern, Little had previously approached her on 26 July and said he thought she should take over as Labour leader then as he was of the opinion he couldn't turn things around for the party, although Ardern declined and told him to "stick it out".
At her first press conference after her election as leader, she said that the forthcoming election campaign would be one of "relentless positivity". Immediately following her appointment, the party was inundated with donations by the public, reaching NZ$700 per minute at its peak. Ardern's election was followed by a spate of positive coverage from many sections of the media, including international outlets such as CNN, with commentators referring to a 'Jacinda effect' and 'Jacindamania'.
After Ardern's ascension to the leadership, Labour rose dramatically in opinion polls. By late August they had reached 43 per cent in the Colmar Brunton poll (having been 24 per cent under Little's leadership) as well as managing to overtake National in opinion polls for the first time in over a decade. Detractors noted that her positions were substantially similar to those of Andrew Little, and suggested that Labour's sudden increase in popularity were due to her youth and good looks.
In mid-August 2017, Ardern stated that a Labour government would establish a tax working group to explore the possibility of introducing a capital gains tax but ruled out taxing family homes. In response to negative publicity, Ardern abandoned plans to introduce a capital gains tax during the first term of a Labour government. Finance spokesperson Grant Robertson later clarified that Labour would not introduce new taxes until after the 2020 election. The policy shift accompanied strident allegations by the Minister of Finance Steven Joyce that Labour had a $11.7 billion "hole" in its tax policy.
The Labour and Green parties' proposed water and pollution taxes also generated criticism from farmers. On 18 September 2017, the farming lobby group Federated Farmers staged a protest against the taxes in Ardern's hometown of Morrinsville. New Zealand First leader Winston Peters attended the protest to campaign, but was jeered at by the farmers because they suspected he was also in favour of the taxes. During the protest, one farmer displayed a sign calling Ardern a "pretty Communist". This was criticised as misogynistic by former Prime Minister Helen Clark.
In the final days of the general election campaign the opinion polls narrowed, with National taking a slight lead.
2017 election results
Preliminary results from the general election indicated that Labour received 35.79 per cent of the vote to National's 46.03 per cent. Labour gained 14 seats, increasing its parliamentary representation to 45 seats. This was the best result for the party since losing power in 2008. After the election, Ardern and deputy leader Kelvin Davis negotiated with the Greens and New Zealand First parties about forming a coalition, as the rival National Party lacked sufficient seats to govern alone. Under the country's mixed-member proportional (MMP) voting system, New Zealand First held the balance of power and was, therefore, able to choose the party that would lead a coalition government. With the release of special (including overseas voting) results on 7 October, Labour gained an extra seat on the initial result, to 46 parliamentary seats.
On 19 January 2018, Ardern announced that she was pregnant, and that Winston Peters would take the role of Acting Prime Minister for six weeks after the birth. Following the birth of a daughter, she took her maternity leave from 21 June to 2 August 2018.
Ardern intends to halve child poverty in New Zealand within a decade. In July 2018, Ardern announced the start of her government's flagship Families Package. Among its provisions, the package will increase paid parental leave by 22 weeks and 26 weeks from July 2020, and pay $60-a-week to low and middle-income families with young children.
Ardern is opposed to criminalising people who use cannabis, and has pledged to hold a referendum on whether or not to legalise cannabis in her first term as prime minister.
On 2 February 2018, Ardern travelled to Waitangi for the annual Waitangi Day commemoration; she stayed in Waitangi for five days, an unprecedented length. Ardern became the first female prime minister to speak from the top marae. Her visit was largely well-received by Māori leaders, with commentators noting a sharp contrast with the acrimonious responses received by several of her predecessors.
On 24 August 2018, Ardern removed Broadcasting Minister Clare Curran from Cabinet after she failed to disclose an official meeting. Curran remained a minister outside Cabinet, and Ardern was criticised by the Opposition for not dismissing Curran from her portfolio. On 7 September, Ardern accepted Curran's resignation.
Despite the New Zealand Labour Party campaigning on a capital gains tax for the last three elections, Ardern pledged in April 2019 that the government would not implement a capital gains tax under her leadership.
On 14 March 2020, she announced in response to the coronavirus pandemic in New Zealand that the government would be requiring anyone entering the country from midnight 15 March to isolate themselves for 14 days. Ardern said the new rules will mean New Zealand has the "widest ranging and toughest border restrictions of any country in the world". On 19 March, Ardern announced that New Zealand's borders would be closed to all non-citizens and non-permanent residents, beginning at midnight on 20 March (NZDT).
On 5 November 2017, Ardern made her first official overseas trip to Australia, where she met Australian Prime Minister Malcolm Turnbull for the first time. Relations between the two countries had been strained in the preceding months because of Australia's treatment of New Zealanders living in the country, and shortly before taking office, Ardern had spoken of the need to rectify this situation, and to develop a better working relationship with the Australian government. Turnbull described the meeting in cordial terms: "we trust each other...The fact we are from different political traditions is irrelevant". Ardern flew to Vietnam on 9 November for her first visit to an APEC summit.
On 20 April 2018, Ardern attended the Commonwealth Heads of Government Meeting 2018 in London, where she was selected to deliver a toast to the Commonwealth at a state banquet of world leaders. She also had her first private audience with the Queen.
On 5 September, Ardern travelled to Nauru, where she attended the Pacific Islands Forum. Media and political opponents criticised her decision to travel separately from the rest of her contingent so that she could spend more time with her daughter. Critics charged that the additional flight would cost taxpayers up to NZ$100,000. Ardern had earlier rebuffed suggestions that she should not attend the Forum, citing tradition; she would have been the first New Zealand prime minister since 1971 to not attend the Forum outside an election cycle. She was later criticised for not meeting refugees in Nauru.
On 24 September, Ardern became the first female head of government to attend the United Nations General Assembly meeting with her infant present. Her address to the General Assembly on 27 September praised the United Nations for its multilateralism, expressed support for the world's youth, and called for immediate attention to the effects and causes of climate change, for the equality of women, and for kindness as the basis for action.
On 23 September 2019, at a United Nations summit in New York City, Ardern had her first formal meeting with Donald Trump. She reported that the US President showed "interest" in New Zealand's gun buyback scheme.
On 28 February 2020, Ardern criticised Australia's policy of deporting New Zealanders, many of whom had lived in Australia but had not taken up Australian citizenship as "corrosive" and damaging to Australia–New Zealand relations.
Christchurch mosque shootings
Ardern visits members of the Muslim community at the Phillipstown Community Centre, 16 March 2019. Captured through a glass window, the photo was widely shared at the time and described by The Guardian as "an image of hope".
On 15 March 2019, 51 people were fatally shot and 49 injured in two mosques in Christchurch. In a statement broadcast on television, Ardern offered condolences and stated that the shootings had been carried out by suspects with "extremist views" that have no place in New Zealand, or anywhere else in the world. She also described it as a well-planned terrorist attack.
In response to the shootings, Ardern announced her government's intention to introduce stronger firearms regulations. She said that the attack had exposed a range of weaknesses in New Zealand's gun laws. Announcing a period of national mourning, Ardern was the first signatory of a national condolence book that she opened in the capital, Wellington. She also travelled to Christchurch to meet first responders and families of the victims. Ardern received international praise for her response to the shootings, and a photograph of her hugging a member of the Christchurch Muslim community with the word "peace" in English and Arabic was projected onto the Burj Khalifa, the world's tallest building. A 25-metre mural of this photograph was unveiled in May 2019. When New Zealand started a royal commission to investigate the attacks, she stated, "It will look at the actions of SIS [Security Intelligence Service], the GCSB [Government Communications Security Bureau], police, customs, immigration and any other relevant government departments or agencies".
Ardern believes the retention or abolition of Māori electorates should be decided by Māori, stating, "[Māori] have not raised the need for those seats to go, so why would we ask the question?" She supports compulsory teaching of the Māori language in schools.
Ardern is a distant cousin of former National MP for Taranaki-King Country Shane Ardern. Due to the cousins being in opposing parties, Ardern has previously joked "we don't talk about it". Shane Ardern left Parliament in 2014, three years before Jacinda Ardern became Prime Minister.
Ardern owned a ginger-and-white polydactyl cat named Paddles, which became a celebrity as the "First Cat" after Ardern took office, even having a Twitter account established in her name. Paddles died in early November 2017 after being hit by a car in the Auckland suburb of Point Chevalier.
On 19 January 2018, Ardern announced that she was expecting her first child in June, making her New Zealand's first prime minister to be pregnant in office. Ardern was admitted to Auckland City Hospital on 21 June 2018, and gave birth to a girl at 4:45 pm (04:45 UTC) that day, becoming only the second elected head of government to give birth while in office (after Benazir Bhutto in 1990).
On 24 June, Ardern revealed her daughter's given names as Neve Te Aroha. Neve is an anglicised form of the Irish name Niamh, meaning "bright"; Aroha is Māori for "love", and Te Aroha is a mountain in the Kaimai Range, near Ardern's home town of Morrinsville.

Now that New Zealand's Prime Minister Jacinda Ardern has hit world headlines by becoming only the second elected head of government to give birth in office, attention has naturally been drawn to the first such leader – Pakistan's late two-time Prime Minister Benazir Bhutto.
