He would be back in court on Monday, National Prosecuting Authority spokeswoman Natasha Ramkisson said.
Mdunge faces three charges of fraud and one of uttering a forged document.
Two of the fraud charges relate to his presentation of an allegedly fake matric certificate when he joined the police in 1987.
He resigned last year, after the allegation surfaced in September, and he was arrested in October.
The third fraud charge relates to his presentation of the alleged fraudulent certificate to the University of SA to get admission to a national diploma in police administration course.
In March, a provincial education department official told the court the department had no record of a matric certificate for Mdunge, and the one Mdunge claimed was his had been tampered with unlawfully.
His former teacher told the court in May that he personally handed Mdunge a matric certificate.
Vusimuzi Donald Duke Khumalo told the court he was Mdunge’s English teacher in 1984 and 1985, when Mdunge matriculated from Ukusa High School in Hammarsdale.
