Norma Mngoma to testify about estranged husband Malusi Gigaba at Zondo commission Share Johannesburg - Nomachule (Norma) Mngoma, the estranged wife of former Cabinet minister Malusi Gigaba, is expected to testify at the Zondo commission on Friday. Mngoma, who recently changed her surname back to her maiden name, will finally have her say at the inquiry following public promises that she was willing to appear. The commission confirmed the news on Thursday. Gigaba plans to apply to the inquiry to cross-examine Mngoma and to ask the commission not to make her evidence public. Mngoma's evidence is expected to focus on Gupta-related matters. She was married to Gigaba while he served in key ministerial positions – as minister of public enterprises and as minister of finance.
