CEO Themba Mthethwa’s extended employment contract was to have expired on December 31, spokesman Oupa Segalwe said.
However, he resigned last month indicating that he had received a better offer elsewhere.
CFO Dumisani Dlamini, also resigned last month after accepting a better offer elsewhere.
“Due to the Public Protector South Africa’s limited resources, the CEO and CFO are appointed at lower levels compared to their equals in government,” said Segalwe.
“For example, the CEO should have been at the level of a director general while the CFO should have been at the level of the deputy director general.”
In 2012, Mthethwa was at the centre of allegations of maladministration and financial misconduct in the Office of the Public Protector.
These allegations were contained in an anonymous 12-page document, allegedly by a group of employees.
At the time, Public Protector Thuli Madonsela confirmed that she was investigating the allegations.
