They will join The X Factor SA's presenter Andile Ncube who was announced at the beginning of last month.
The X Factor South Africa will start on SABC1 on Saturday 6 September at 18:00 on SABC1.
It remains to be see whether South African viewers will be able to keep up and have as big an appetite for multiple TV talent shows running concurrently on South African television and which of these shows will be able to not only grab viewers' interest but manage to maintain it.
Besides the first season of The X Factor SA on Saturdays on SABC1, there will be Idols X on M-Net and Mzansi Magic (DStv 161) on Sundays at 17:30, and SA's Got Talent's 5th season on e.tv and those judges making their "X'es" also starting in September - a lot of homework for viewers, and TV critics.
The X Factor SA, produced by Rapid Blue, will unspool over the course of 15 weeks on SABC1, starting on 6 September and ending with a live finale in Durban on 13 December.
The winner receives a Sony Music Entertainment contract and R300 000 as a cash prize.
"This is a launch pad for somebody with talent but you also have to have the ambition, the work ethic and everything else," says Maijang Mpherwane, SABC1 channel head.
"SABC1 is delighted that Zonke, Arno Carstens and Oskido have joined The X Factor South Africa judging panel. They have years of experience both here and abroad," says Maijang Mpherwane.
"They are driven and hard-working and bring their extensive know-how and knowledge to the show".
Zonke is a multi-award winning singer, songwriter and producer and a multiple South African Music Awards winner. Her father was Vuyisile Dikana, the drummer of Black Slave and the Flamingo, and her late stepmother, Anneline Malebo, sang for Joy.
Arno Carstens is the lead singer of the Springbok Nude Girls, also won multiple South African Music Awards, and has toured South Africa, Europe, the United States and the United Kingdom.
Oskido is an award-winning producer, performer, radio presenter and record producer who started Kalawa Records, and is a member of Brothers of Peace (B.o.P.)
