Steenkamp, the girlfriend of Olympian Oscar Pistorius, found shot dead in his home Thursday, was a contestant on the Tropika Island of Treasure 5 show, The Saturday Star in Johannesburg reported.
Creator Samantha Moon said show members were devastated by the loss of Steenkamp, 30.
While the decision to continue broadcasting the show had difficult, Moon said "Reeva was an intelligent, beautiful and amazing woman and we feel it would be an injustice to keep that unknown from those who did not know her personally."
Moon added, "Reeva was a wonderful human being and an extremely talented and intelligent woman. Her kind and loving spirit was evident to all who knew her and her zest for life will be truly missed."
"Every episode that she is in, every frame that she so ably dominates shines with her light, her laughter echoes in every conversation, and we want to share these special memories with the rest of South Africa," Moon said.
Pistorius has been arrested in Steenkamp's death. A double amputee, he made Olympic history by running on carbon fiber blades that earned him the name "Blade Runner."
