List of high commissioners of New Zealand to the United Kingdom

The high commissioner of New Zealand to the United Kingdom is New Zealand's foremost diplomatic representative in the United Kingdom of Great Britain and Northern Ireland, and in charge of New Zealand's diplomatic mission in the United Kingdom.

The High Commission of New Zealand is located in London, the United Kingdom's capital city.

The high commissioner was formerly accredited as ambassador of New Zealand to Ireland, which is now a resident mission in Dublin since 2018.

As New Zealand was created as a part of the British Empire, its diplomatic relationship with the United Kingdom is its longest-standing; the position of high commissioner in London pre-dates New Zealand's Dominion status by two years, the Balfour Declaration of 1926 by 21 years, and the adoption of the Statute of Westminster of 1931 by 42 years.

As fellow members of the Commonwealth of Nations, diplomatic relations between New Zealand and the United Kingdom are at governmental level, rather than between heads of state, with member countries exchanging high commissioners, rather than ambassadors.
