In the two months since the project was launched, no rhinos have been poached in the Tembe national park and the Ndumo game reserve.
The initiative sees the rhino's horns injected with a poisonous chemical that activates when a rhino is poached.
Ezemvelo spokesperson Musa Mntambo says the project does have its challenges.
"This is not only done by us, Ezemvelo, there are other vets coming from other organisations. So we have to bring them together and work together.
"And it's also very costly because for each rhino it costs R8 000 to infuse," he said.
KwaZulu-Natal has lost 75 rhinos to poaching since the beginning of the year.
