A public apology to the family of a teen killed by The X Factor contestant Shae Brider will screen on the show's next two episodes.
Brider, 29, was sentenced to 8 years in jail for his part in the manslaughter of Jeremy Frew, 16, in Wanganui in 2004.
He was one of four charged with Jeremy's death after what the judge described as a "rampage of violence" where the group assaulted Daniel Grey, Greg Parnell and Robert Kerrigan on the same night.
On Tuesday, Brider's successful X Factor audition was broadcast with a segment describing the crime.
"I met some dudes and we went to a bonfire," the Masterton man told the show. "There was a commotion with two of them and one of them stabbed the other one and he ended up passing away."
