The high commissioner of New Zealand to Fiji is New Zealand's foremost diplomatic representative in the Republic of the Fiji Islands, and in charge of New Zealand's diplomatic mission in Fiji.
The high commission is located in Suva, Fiji's capital city. New Zealand first maintained a resident Head of Mission in Fiji since 1970.
As fellow members of the Commonwealth of Nations, the countries exchange high commissioners, rather than ambassadors. This was not the case between 1987 and 1997; after the Coups of 1987, Fiji was expelled from the Commonwealth, but rejoined after the promulgation of a new constitution in 1997. Hence, from 1987 until 1997, New Zealand was represented in Fiji by an ambassador.
In the Commonwealth of Nations, a high commissioner is the senior diplomat, generally ranking as an ambassador, in charge of the diplomatic mission of one Commonwealth government to another. Instead of an embassy, the diplomatic mission is generally called a high commission.
