The father of murdered Lower Hutt schoolgirl Karla Cardno has been denied parole for his own crimes against a teenage girl.

Gary John Duffin was sentenced to nine years in prison in 2010 after a High Court jury found he and his wife Sharyn Lee Hills were guilty of raping a 14-year-old girl who worked for them as a prostitute.

He was also convicted of indecent assault and sexual violation relating to the offending between May 1991 and December 1992 - about two years after Duffin's daughter Karla Cardno, 13, was kidnapped, raped, tortured and buried alive on a beach by Paul Dally.

Duffin was denied parole when he appeared before the Parole Board at Rimutaka Prison today, One News reported.

At sentencing, his defence lawyer Greg King said the profound impact of his daughter's death should be taken into account.

But Duffin reportedly told Parole Board chairman Justice Warwick Gendall today: "I must admit I may have used some things as an excuse."

Duffin will become eligible for parole again next year.
