Her father, Swannie Swanepoel, told the public broadcaster he had received confirmation of her release from the department of international relations, SABC reported on Tuesday.
Beetge was found with 10.2kg of cocaine in her luggage at Sao Paulo’s Guarulhos International Airport in 2008.
She was sentenced to 12 years in jail.
Beetge was procured by Sheryl Cwele to smuggle cocaine from South America.
Cwele, the ex-wife of State Security Minister Siyabonga Cwele, and her co-accused Frank Nabolisa were found guilty of drug dealing by the Pietermaritzburg High Court in May 2011.
The two tried to have their convictions overturned by the Supreme Court of Appeal in 2012, however the court increased their sentences from 12 to 20 years.
