The wife or husband of the Prime Minister of New Zealand holds no official office and, as such, is not given a salary or official duties, but the prime minister's spouse may be expected to act as hostess or host of Premier House. The current prime minister, Christopher Luxon, is married to Amanda Luxon.
When Henry Sewell became the country's first premier in 1856, his wife, Elizabeth Kittoe, became the first person to fill the role. The first husband to the prime minister was Burton Shipley, Jenny Shipley's husband, in 1997. The 23rd prime minister, Michael Joseph Savage, was a bachelor during his term, and prime minister Jacinda Ardern was in an unmarried relationship with Clarke Gayford during her tenure from 2017 to 2023.
The current spouse of the prime minister of New Zealand is Amanda Luxon, as her husband became prime minister on 27 November 2023.
The prime minister's spouse has no official duties. Some earlier spouses stayed mainly at home and took little part in public life.
However, most recent prime ministers' spouses have been involved in charities or community organisations, working to raise public awareness, funds, and support for a range of causes. They generally assist their partners in political campaigns, and participate in official duties that come with the position, such as hosting foreign dignitaries, and, in particular, entertaining the spouses of dignitaries; accompanying the prime minister on national and international trips; and attending conferences and functions. They have attended the opening of Parliament; hosted visitors at Premier House; visited Buckingham Palace, the White House, or the Japanese Imperial Palace; and been present at royal coronations and conferences.
Some prime ministers' spouses have received official recognition for their services to the community with a damehood:
Muldoon was the first spouse of a prime minister to be provided with an official secretary for dealing with her correspondence.
Domestic partner; engaged since May 2019.
While remaining married, Chris and Jade Hipkins separated in 2022.
