The New Zealand Operational Service Medal

Overview

The New Zealand Operational Service Medal (NZOSM) was instituted in 2002 to recognise New Zealanders who have undertaken operational service since 3 September 1945. Operational service is defined as service exceeding the normal requirements of peacetime, involving a credible military threat from enemy forces, insurgents, or other hostile entities.

The NZOSM is awarded to New Zealand citizens and permanent residents in addition to any New Zealand, Commonwealth, or foreign campaign medals. It is awarded only once to an individual, regardless of how many times they have deployed on operations.

Description

The NZOSM is silver in colour and circular in shape. On the obverse, the New Zealand Coat of Arms indicates that the medal specifically recognises service on behalf of New Zealand. The reverse depicts a kiwi, facing to the right, with the inscription 'FOR OPERATIONAL SERVICE'. The straight line below the kiwi’s feet represents land, the wavy line represents sea and the background field represents air.

The colours of the ribbon allude to those generally regarded as the national colours of New Zealand, black and white. These colours were first adopted by the New Zealand troops in the South African War (1899-1902). They were used for the New Zealand War Service Medal; the New Zealand Service Medal 1946-1949; and the East Timor Medal . The distinctive design makes the statement that it is a New Zealand medal. When worn and overlapped with other medals the distinctive design remains visible.

The NZOSM was issued unengraved until 30 June 2009, except for those who had died on operational service. From 1 July 2009, all NZOSMs have been issued engraved on the bottom rim. For military personnel, the details engraved include the recipient's service number, rank, initials, surname, and corps / service. These details are as at the date of the operational service which qualifies him or her for the NZOSM.

Recipients of an unengraved NZOSM should contact NZDF Personnel Archives and Medals (PAM) if they wish their medal to be engraved.  The best opportunity to have your medal engraved is when you need to add another medal (such as the New Zealand Defence Service Medal) to your mounted medal group.  

There are no clasps or bars for this medal.

    Is the New Zealand Operational Service Medal ever awarded without a campaign medal?

    Yes.  The New Zealand Operational Service Medal (NZOSM) is awarded for seven days' service, while a campaign medal is usually awarded for 30 days' service.  For example, if you served 20 days in an operational area, you may be eligible for the NZOSM without a campaign medal.
