The high commissioner of New Zealand to Samoa is New Zealand's foremost diplomatic representative in Samoa, and in charge of New Zealand's diplomatic mission in Samoa.
The high commission is located in Apia, Samoa's capital city. New Zealand has maintained a resident high commissioner in Samoa since the country's independence in 1962 (from New Zealand).
The high commissioner to Samoa is concurrently accredited as the Consul-General to American Samoa, in which capacity he or she serves under the ambassador to the United States.
As fellow members of the Commonwealth of Nations, diplomatic relations between New Zealand and Samoa are at governmental level, rather than between heads of state. Thus, the countries exchange high commissioners, rather than ambassadors.
