"We were... advised at this point in time that it has been denied and it will be considered again in one year's time," Tania Koen, a lawyer for the victim's family, told AFP. The Department of correctional services said Pistorius had not completed the minimum detention period required for parole.
Pistorius killed Reeva Steenkamp, a model, in the early hours of Valentine's Day 2013, firing four times through the bathroom door of his ultra-secure Pretoria house, in a killing that shocked the world.
Once the darling of the Paralympic movement for pushing for greater recognition and acceptance of disabled athletes, The athlete, known as "Blade Runner" for his carbon-fiber prosthetic legs, went from public hero to convicted murderer in a trial that drew worldwide interest.
Steenkamp's mother, June, is to appear before the board to "make representations" also on behalf of her husband, Barry, who is unable to travel because of ill health, lawyer Tania Koen said.
Lawyer Tania Koen, representing Steencamp's family, told reporters "They don't feel that he should be released. They feel that he has shown no remorse."
Pistorius met with Steenkamp's parents last year, part of a process that authorities say aims to ensure inmates "acknowledge the harm they have caused to their victims and the society at large."
Pistorius has served more than half his sentence, which he began in 2014.
