In Opposition, 2014–2017 Peeni Henare won the Tāmaki Makaurau electorate ahead of Rangi McLean of the
Māori Party in 2014. In 2016, a member's bill submitted by Henare which aimed to ban the import of goods produced by slave labour was drawn from the ballot. The bill had been first introduced by
Maryan Street and defeated at its first reading in 2009. It was again defeated at its first reading in 2016 due to opposition from the
National Party and
Act New Zealand.
In Government, 2017–2023 During the
2017 New Zealand general election, Henare was re-elected in the Tāmaki Makaurau electorate, winning 9,396 votes. Henare was elected as a Minister outside Cabinet by the Labour Party caucus following Labour's formation of a
coalition government with
New Zealand First and the
Greens in October 2017. He assumed the portfolio of Minister for
Whānau Ora, which falls under the purview of
Te Puni Kōkiri (the Ministry for Māori Development). Following a
cabinet reshuffle in late June 2019, Henare was appointed as
Minister of Civil Defence. During the
2020 general election, Henare retained Tāmaki Makaurau, defeating the Māori Party candidate and co-leader
John Tamihere and Green co-leader
Marama Davidson. When the official results were released, Henare had a majority of 956, but after the Māori Party requested a recount in Tāmaki Makaurau, Henare's majority fell slightly to 927. In November 2020, Henare was announced as
Minister of Defence and Minister for
Whānau Ora. He also assumed the health, housing and tourism associate portfolios with responsibility for Māori health and housing. In May 2022 he indicated to Labour Party President
Claire Szabó that he would possibly be unwilling to recontest
Tāmaki Makaurau at the
2023 New Zealand general election, preferring instead to contest the election as a list-only candidate. In November 2022, Henare in his capacity as Defence Minister visited Polish
Minister of National Defence Mariusz Błaszczak. He subsequently visited Ukrainian
Defence Minister Oleksii Reznikov and paid tribute to the fallen at
The Wall of Remembrance of the Fallen for Ukraine in
Kyiv. Henare's visit to Ukraine marked the first visit by a New Zealand cabinet minister since the
2022 Russian invasion of Ukraine. During a cabinet shuffle that occurred on 31 January 2023, Henare was succeeded as Defence Minister by
Andrew Little. Henare became the Minister for the
Accident Compensation Corporation (ACC),
Minister of Tourism, and Minister for the Environment while retaining the Associate Minister of Health portfolio with responsibility for Māori.
In Opposition, 2023–2026 During the
2023 New Zealand general election held on 14 October, Henare lost Tāmaki Makaurau by a narrow margin of 42 votes to
Te Pāti Māori (Māori Party) candidate
Takutai Tarsh Kemp. He was re-elected to Parliament on the party list. In early November 2023, Henare applied for a judicial recount. On 15 November, the
Electoral Commission found that Kemp has won by a margin of 42 votes. Following the formation of the
National-led coalition government in late November 2023, Henare became spokesperson for defence, sport and recreation, and associate health in the
Shadow Cabinet of Chris Hipkins. On 5 December 2023, Henare was granted retention of the title
The Honourable, in recognition of his term as a member of the
Executive Council. In February 2024, Henare attracted media attention after he used a metaphor involving a gun during a
Māori language speech prior to
Waitangi Day. Criticising the Government's policies towards Māori, he stated: "This is a fight that will not be fought just in Parliament. I lift my gun, and I let the shots do the talking." Henare subsequently clarified that he was referring to a "figurative gun" rather than an actual gun.
ACT leader
David Seymour described Henare's metaphor of shooting people as inappropriate. Henare was defended by Labour Party leader
Chris Hipkins, who argued that Henare was using a metaphor and not making an actual death threat. Hipkins also responded that Seymour was not in a position to "throw stones" given his 2023 remarks about blowing up the
Ministry for Pacific Peoples. On 10 December 2024,
House Speaker Gerry Brownlee referred Henare along with
Te Pāti Māori (TPM) MPs
Hana-Rawhiti Maipi-Clarke,
Rawiri Waititi and
Debbie Ngarewa-Packer to the Privileges Committee for leading a
haka (
Ka Mate) that interrupted vote proceedings during the first reading of the
Treaty Principles Bill on 14 November 2024. On 13 March 2025, Henare appeared before the Privileges Committee where he apologised for getting out of his seat but refused to apologise for participating in the haka. On 26 March, the Committee found that Henare had acted in a "disorderly" way in joining the TPM-led haka but ruled that his actions did not amount to "contempt." Following a
cabinet reshuffle on 7 March 2025, Henare became part of Hipkins' new economic team, gaining the economic development and associate health portfolios. He retained the Māori-Crown Relations
Te Arawhiti and defence portfolios but lost the sports and recreation portfolio. In July 2025, Henare was confirmed as Labour's candidate for
that year's by-election in the Tāmaki Makaurau electorate, which had been called following the death of
Takutai Tarsh Kemp. During a candidate debate with
Te Pāti Māori candidate
Oriini Kaipara held on 20 August 2025, Henare voiced support for repealing the National-led coalition government's
Gangs Act 2024's ban on
gang patches. Henare's remarks contradicted Labour leader Hipkins' position that the party would not repeal the ban on gang patches. In response, Labour's deputy leader
Carmel Sepuloni clarified that Henare's remarks did not represent official party policy. In response, National Party MP and
Justice Minister Paul Goldsmith questioned whether Labour would commit to its promise not to repeal the gang patch ban. On 6 September, Henare lost the Tāmaki Makaurau by-election to Kaipara by a landslide. Based on the preliminary count, Henare won 3,093 votes, coming second place to Kaipara's 6,031 votes. During his concession speech, Henare described the
National-led coalition government as their main opposition. On 3 February 2026, Henare announced he had not put himself forward to be nominated as the Labour Party candidate for his former Tāmaki Makaurau seat, and that he would shortly resign from Parliament would not seek a place on the Labour Party list in the
2026 general election. During his valedictory speech to Parliament on 11 March, Henare urged his parliamentary colleagues to move away from "gotcha style politics" in order to rebuild trust in political institutions. Henare's resignation as an MP took effect at 11:59pm on 15 March. ==Personal life==
