The New Zealand Meritorious Service Medal is a meritorious and long service award for members of the New Zealand Defence Force.

In 1985, a Royal Warrant established the current criteria for the medal making all members of the Army, Navy, and Air Force eligible for the award.

The obverse bears the effigy of the Sovereign of New Zealand, surrounded by the inscription ELIZABETH II DEI GRATIA REGINA FID.

The reverse bears the inscription For Meritorious Service surrounded by a laurel wreath, surmounted by a royal crown.
