Model, actress and radio personality Pearl Thusi was in a car accident that left her and her daughte.
So far the campaign has seen Nelson Mandela Square management asking top athlete Oscar Pistorius and Afro-pop group Freshlyground to design rhino sculptures that were unveiled to the public recently.
Now the square has roped in the services of leading Scandal actors Sello Maake ka Ncube, known as Daniel Nyathi in the e.tv soapie, and Ntathi Moshesh, who plays Mo.
"We have asked the two actors to come on board and they have responded to the call to design two rhinos of their own, which they will unveil on Friday," said Square spokesman Huibri Schalkwyk.
"They will be assisted by professional artists in designing these two sculptures," he added.
The rhino campaign is run by the Square in conjunction with the Wildlands Conservation Trust, a non-profit organisation and registered charity.
"Our vision is a sustainable future for all and to achieve this we are progressively developing and implementing Wildlands initiatives across the country," the Trust said in a statement. "At the current rate of poaching we are set to lose over 400 rhino in the year 2011.
"Wildlands have responded by establishing a rhino conservation project, Project Rhino, starting in the Zululand region which aims to place rhino populations in KwaZulu-Natal under constant GPS surveillance."
