Early Life and Education
Born May 8, 1978, in Soweto, Gauteng, Kubayi grew up in a shack with her four siblings. Her mother worked as a domestic worker, earning just enough to feed their family. She became pregnant at 17 and gave birth to her first son, dropping out of school temporarily but returning after childbirth.
She matriculated from Thusa-Setjhaba Secondary School in 1997 as the top achiever, then earned a BA in Psychology and Sociology from Vista University (2000), a Project Management Diploma from Damelin (2002), and a Master’s in Public and Development Management from Wits (2015). She also completed Harvard’s Programme for Leadership Development.
Career
Kubayi began as a Community Developer in the non-governmental sector, then worked in banking at FNB and Nedbank before joining Parliament in 2009 as an ANC Member.
Her cabinet career started in October 2016 under President Jacob Zuma as Communications Minister, followed by brief roles as Energy Minister (2017) and Science and Technology Minister (2018–2019).
Under Cyril Ramaphosa, she became Tourism Minister (2019–2021), Acting Health Minister during the pandemic’s third wave (2021), Human Settlements Minister (2021–2024), and now Justice and Constitutional Development Minister (2024–present).
In 2022, she contested for ANC Deputy President and was elected to the ANC’s National Working Committee. She also chairs the Economic Transformation subcommittee and serves on the Global Artificial Intelligence Council.
Personal Life
Kubayi keeps her personal life private but has two children, her first son born at 17, and another with her former husband Joel Sihle Ngubane. They married in September 2017 but divorced in 2021. She still lives in Soweto, maintaining ties to her roots.
Net Worth
Kubayi’s net worth is estimated at around R8–R12 million (around $430,000–$650,000). As a cabinet minister since 2016, she earns roughly R2.3–R2.5 million annually plus allowances. Her wealth likely comes from government salary accumulated over nearly a decade in cabinet, property investments, and her prior banking career. These figures remain unconfirmed.
Controversies
Kubayi’s career has faced significant scrutiny: defending Jacob Zuma during corruption trials, controversial oil reserve handling as Energy Minister, the Labour Court overturning her dismissal of a deputy director-general, R16 million travel spending criticized in 2025, and a fabricated WhatsApp conversation falsely linking her to prosecutorial decisions against Deputy President Paul Mashatile.
Critics also questioned her Health Minister appointment as a non-medical doctor, and an ANC Limpopo group rejected her nomination there citing tribal dynamics.
Mmamoloko Kubayi’s story is one of resilience. From a Soweto shack to South Africa’s most powerful political positions, she proves hard work and determination overcome even the toughest beginnings. Her journey hasn’t been perfect, filled with criticism and legal challenges, but she remains central to South Africa’s political landscape.
