The Sevens heavyweights were looking to secure their first title under new coach Ben Ryan and they responded by overwhelming New Zealand 44-0 in the semi-final.
Wary of maintaining their composure after handing the Series leaders, defending series champions and Gold Coast Sevens victors their biggest defeat in the competition, Fiji then took full control against another series favourite.
Fiji scored four tries before South Africa mustered up a delayed response to put themselves in contention to add to the sole IRB Sevens series they won in 2006.
Making an appearance in their first final in five tournaments that dates back to the 2012-13 season, Fiji dotted down twice through Benito Masilevu before South Africa's ill discipline cost them dearly.
South Africa were reduced to six men for two minutes and Fiji capitalised through Samisoni Viriviri almost immediately to hold a 19-0 lead at half-time.
They extended that lead when Osea Kolinisau darted through untouched following some poor retention from a South Africa scrum.
Jona Tuitoga was sinbinned and South Africa responded with tries to Cheslin Kolbe and Samplie Mastriet, but when Leo Naikasau scored Fiji's fifth the match was well and truly over.
Chris Dry scored a consolation try for South Africa but it would be Fiji who were left celebrating under Ryan.
