The High Commissioner from New Zealand to Tonga is New Zealand's foremost diplomatic representative in the Kingdom of Tonga, and in charge of New Zealand's diplomatic mission in Tonga.
The High Commission is located in Nukuʻalofa, Tonga's capital city. New Zealand has maintained a resident High Commissioner in Tonga since 1976.
As fellow members of the Commonwealth of Nations, diplomatic relations between New Zealand and Tonga are at governmental level, rather than between Heads of State. Thus, the countries exchange High Commissioners, rather than ambassadors.
