"A few hours ago, a legend departed this land. The great Nyembezi Kunene - actor, director, playwright and producer, has passed on. Following a prolonged illness, Nyemza lost his battle with Diabetes and died peacefully at the Lesedi Hospital in Soweto, late on Saturday evening. He will be remembered for his many roles he played in various TV and Film productions in a career spanning well over three decades. May his soul Rest In Peace. You fought a great fight, a hero to the end. We will miss you Nyemza. This is the final curtain call, after decades spent entertaining South African audiences. You stayed true to your craft till the end. You were a great father and your teachings will live on, not only in your children's lives, but also in the lives of many your work and passion for the performing arts have changed. Hambe kahle Mntimande! Bambolunye! Ngwenya! Madonsela! Rest in Peace Baba"
