"I'm very scared because up until now we have had three postponements of three years. I'm scared it's a prelude to his release," said Kylie's mother, Dawn Smith of Owaka, yesterday.
"We mistakenly thought life meant life."
A month before the rape and murder of Kylie, Bailey was charged with attempted rape in Ettrick and was on bail at the time of the Owaka 15-year-old's death in 1991.
He was armed with a .22 calibre rifle when he approached Kylie, who was riding a horse. He forced her into his car then drove into an area of bush, where he raped and murdered her. He was jailed for life.
Mrs Smith and her late husband, Bevan, have fought to keep Bailey in prison, for postponements of his parole hearings, and for changes to the justice system.
Mr Smith died, aged 60, on Christmas Day 2011.
Mrs Smith yesterday said appearing before the parole board was not difficult, but the waiting afterwards was.
The parole board is expected to release its written recommendation tomorrow.
