The New Zealand Service Medal 1946–1949 is a New Zealand campaign medal for service in Occupied Japan at the end of World War II.

In 2002 the Royal Warrant was amended to also recognise service between September 1945 and March 1946, including service by the crews of HMNZS Gambia and HMNZS Achilles in Japanese waters.

[1] The medal was awarded to all those, military or civilian, who served with the occupation forces.

Service terminated by death, wounds or disability due to service, withdrawal at the direction of the New Zealand Government for official reasons, or the award of a Royal Honour for gallantry, bravery, or meritorious service, qualified for the award of the medal, regardless of whether the length of service requirement had been met.

About 13,000 New Zealanders, including several hundred women, are eligible for this medal.
