The medal was awarded to all members of the New Zealand armed forces who, between 29 May 1964 and 27 January 1973, either:
served for 28 days, continuous or aggregated, in ships or craft employed in operations on inland waters or off the coast of Vietnam;
served for one day or more on the posted strength of a unit or formation on land in Vietnam;
conducted one operational sortie over Vietnam or Vietnamese waters by aircrew on the posted strength of a unit allocated for direct support of operations in Vietnam;
served for 30 days or more, continuous or aggregated, on official visits, inspections or other occurrences of a temporary nature on duty in Vietnam, or in ships or craft engaged in operations off the Vietnamese coast.
Service terminated by death or wounds, or the award of a decoration for gallantry, led to the immediate award of the medal, regardless of whether the qualification period had been fulfilled.
The Vietnam Medal is a circular medal made of nickel-silver. The obverse bears the crowned effigy of Queen Elizabeth II with the inscription 'ELIZABETH II DEI GRATIA REGINA F.D.'.[1]
The reverse of the medal has the word 'VIETNAM' at the top centre above a depiction of a man standing between two symbolic spheres, "in representation of the ideological war in Vietnam".[2]
The medal ribbon contains a broad central stripe of bright yellow surmounted by three thin red stripes (representing the Republic of Vietnam). The ribbon also has a blue stripe to represent the Navy, two red stripes for the Army and a light blue stripe for the Air Force.
