North West Transport Investments (NTI), with subsidiaries North West Star and Atteridgeville Bus Service, runs subsidised commuter buses for the province. It was placed in business rescue on 21 July 2022. Over the same period companies owned by Suliman Carrim received more than ten provincial transport tenders totalling about R251 million, the largest a R168 million commuter-transport contract awarded to the Tansnat Coachlines / Ziggy Investments joint venture.
Proclamation 348 of 2026, signed on 11 September and announced on 14 September 2026, authorises the SIU to investigate procurement and contracting at NTI and its subsidiaries: the Tansnat/Ziggy contract, fuel supply by Zentrafor Fuel, a 28 July 2023 vehicle-rental agreement, a 7 July 2023 sub-contractor agreement, claims lodged by Tansnat/Ziggy against the entities, and the conduct of the business rescue practitioner. The SIU will test compliance with Treasury prescripts and whether individuals or entities received undue benefits; findings can be referred to the NPA and pursued through the Special Tribunal.
The proclamation follows Madlanga Commission evidence on payments between Carrim, the late taxi boss Jotham "King Mswazi" Msibi and Katiso Matlala: R700,000 to SANTACO, R1 million to Tucofin (of which Msibi was a director), R10 million from Carrim to Matlala in June 2024, and R500,000 to a company linked to Morgan Maumela's sister. The Commission resolved to lay charges against Carrim for failing to appear. Carrim denies paying or receiving kickbacks and describes the R10 million as an investment.
