Order of wear
The position of the Pro Merito Medal of 1967 in the official order of precedence was revised three times after 1975, to accommodate the inclusion or institution of new decorations and medals, first upon the integration into the South African National Defence Force on 27 April 1994, again when decorations and medals were belatedly instituted in April 1996 for the two former non-statutory forces, the Azanian People's Liberation Army and Umkhonto we Sizwe, and again when a new series of military orders, decorations and medals was instituted in South Africa on 27 April 2003. The position of the Pro Merito Medal of 1967 remained unchanged, as it was on 27 April 1994, upon the latter two occasions ;South African Defence Force until 26 April 1994:
* Preceded by the Southern Cross Medal of the Republic of South Africa.
* Succeeded by the Police Star for Outstanding Service of the Republic of South Africa.
