The New Zealand War Service Medal (NZWSM)was a New Zealand campaign medal for service in World War II. The NZWSM was approved in 1946, and was awarded to members of the New Zealand armed forces, the National Military Reserve, and the Home Guard. The NZWSM was awarded in addition to the standard Commonwealth campaign awards for World War II. This medal was the first distinctively ‘New Zealand' campaign medal, which was emphasised by the use of the fern leaf motif on the reverse and the national colours of black and white in the ribbon. The NZWSM was issued unnamed.
