After beginning his officiating career in the '80s, McLeod became a FIFA referee in 1993.
"In the 1980s Ian was a pioneer and one of the first white referees to enter into the then-NSL (National Soccer League)," assistant referee Ari Soldatos told TimesLive.
"There were others like Stan Swart‚ but they never were able to make the impact on the international stage that Ian did."
He was the first South African to referee at a World Cup when he did so in the 1998 tournament in France, overseeing the match between Spain and Paraguay.
He also refereed at the 1997 FIFA Confederations Cup, as well as several Africa Cup of Nations tournaments.
In later years, he served as a refereeing instructor for the Confederation of African Football (CAF) and as a FIFA assessor.
By the time of his death, he was the Senior Referees Manager at SAFA.
