Tian Olivier has been appointed SABC's new acting chief executive and James Aguma has taken up the reins of acting chief financial officer, the national broadcaster said on Friday.
"Mr Olivier and Mr Aguma's appointments are based on their extensive knowledge and a proven track record as senior managers currently at the SABC," spokesman Kaizer Kganyago said in a statement.
"The SABC board is confident that these appointments will provide the required leadership to turn around the SABC while maintaining public broadcasting mandate."
This follows the resignation of the public broadcaster's CEO Lulama Mokhobo and the dismissal of its CFO Gugu Duda.
Kganyago said the Commission for Conciliation, Mediation and Arbitration had found Duda guilty of misconduct, and she was dismissed on Wednesday. He did not provide further details.
Duda was suspended in September 2012 in connection with procurement and financial irregularities.
Last month, Public Protector Thuli Madonsela had also found that former Communications Minister Dina Pule had interfered "unduly" in Duda's appointment as SABC's CFO.
