The Tenderpreneur and the Printing Firm: Wicknell Chivayo and Renform (2024)

Creative Roll: Producer, Host, Music and Sound mixing and editing, Research and Investigation

In this podcast, Mamello Mosiana unpacks Zimbabwe’s latest corruption scandal, centred on allegations of money laundering, abuse of office, and an allegedly inflated tender awarded by the Zimbabwe Electoral Commission (ZEC) to South African company Ren-Form. At the heart of the controversy is politically connected businessman Wicknell Chivayo, with leaked audio and documents suggesting hundreds of millions of rand were siphoned through the deal.

Joined by Owen Gagare, editor of The NewsHawks, and Michael Marchant, Head of Investigations at Open Secrets, Mamello explores the mechanics of the scandal, its cross-border implications, and what it reveals about corruption and accountability in Zimbabwe. Update: Although the Zimbabwe Anti-Corruption Commission (ZACC) closed its investigation into Chivayo in December 2025, citing a lack of contractual evidence linking him to the tender, South African authorities continue to investigate after the Financial Intelligence Centre found that Ren-Form received more than R1 billion from Zimbabwe’s Ministry of Finance, with over R800 million allegedly transferred to accounts linked to Chivayo.
