On 2 November 2020, prime minister Jacinda Ardern announced Kiri Allan would enter
Cabinet during her second term in parliament, becoming
Minister for Conservation and
Minister for Emergency Management. In addition, Allan also assumed associate ministerial responsibilities in the
Arts, Culture and Heritage and
Environment portfolios. Allan gained prominence in early 2021 when she fronted emergency management press conferences about tsunami threats following
repeated severe earthquakes in the Kermadec Islands that led to the largest evacuation in New Zealand history. Allan's authoritative yet informal communication style was marked out for further praise when it was revealed she had a medical examination that later confirmed a stage 3 cervical cancer diagnosis on the same morning as the disaster. She took three months leave to seek treatment and was eventually declared cancer-free. As conservation minister, Allan oversaw the continued roll-out of the Jobs for Nature employment scheme and implementation of the government's biodiversity strategy. One week later, as Minister for Emergency Management, Allan also announced work to modernise emergency management legislation. As Associate Minister for Arts, Culture and Heritage, Allan was responsible for a new law that marked the celebration of
Matariki with a public holiday starting from 2022. In a June 2022 reshuffle, Allan was promoted from her existing roles to instead be
Minister of Justice. She also joined the government's economic ministerial group as an
Associate Minister of Finance. Following
Jacinda Ardern's resignation as prime minister in January 2023, Allan was speculated to be a
Labour leadership candidate, but declined to run and instead co-nominated senior minister
Chris Hipkins' successful candidacy. Hipkins, as the new prime minister, continued Allan in the justice portfolio, promoted her to tenth in the Cabinet, and also appointed her as Minister for Regional Development and Associate Minister of Transport. She was a lead minister in the response to
Cyclone Gabrielle in the Gisborne and Bay of Plenty regions. As justice minister, Allan was a highly active legislator. At one point it was reported that of the 26 government bills being considered by committees, she was responsible for six of them. She led the government's work on electoral reform, sponsoring legislation on electoral finance reform, broader voter eligibility for New Zealanders living overseas, and reform of the
Māori Electoral Option. A bill to lower the voting age to 16 was considered after the Crown lost in
Make It 16 Incorporated v Attorney-General but was ultimately not progressed. In judicial system reform, Allan completed the government's long-promised
repeal of three-strikes sentencing law, which had been linked to the over-incarceration of
Māori, and also increased access to legal aid. Allan also led proposals related to the sale and supply of alcohol, hate speech, counter-terrorism, name suppression, surrogacy, and
lobbying. Heading into the
2023 general election, the government was criticised as being "
soft on crime". In response, the government adopted "tougher" youth justice policies such as the creation of a new offence for
ram-raiding, which Allan announced on 18 July 2023. Allan later said these policies were not aligned with her personal values and contributed to a mental health breakdown soon after. On 11 September 2023, Allan was granted the use of the honorific prefix
The Honourable for life, in recognition of her term as a member of the
Executive Council. == Controversies ==
