Former health minister Zweli Mkhize’s name has surfaced in a Special Investigating Unit probe, investigating how a KwaZulu-Natal provincial treasury tender ballooned from R3.5 million to R114 million. News24 has revealed that an SIU investigation, completed last February, found that a contract in September 2007, for the provision of forensic risk services, was irregular. Mkhize was MEC for finance and economic development at the time.
