Pistorius killed his girlfriend Reeva Steenkamp in February 2013 after shooting four times through a locked toilet door.
He is currently under house arrest after spending one year of his original five-year sentence in jail.
Pistorius will have to return to court to be re-sentenced, for murder.
Pistorius, a six-time Paralympic gold medallist whose legs were amputated below the knee as a baby, made history by becoming the first amputee sprinter to compete at the Olympics, in 2012, running on prosthetic "blades".
