The child killer and rapist jailed for murdering 6 year-old Teresa Cormack has been denied parole.

Jules Pierre Mikus was found guilty at trial of abducting, sexually violating and murdering the primary school girl in 1987.

Mikus, a recidivist sex offender, maintained he was innocent of the crimes against Cormack.

Cormack was abducted on June 19 that year, the day after her sixth birthday. She was snatched from a suburban Napier street on a cold winter's day and her killer was not convicted for another 15 years.

Mikus, sentenced to life imprisonment in 2002, became eligible for release on parole in February 2012.

Yet he did not appear before the Parole Board, signing a waiver. Mikus signed a waiver again before a May 2012 hearing and also did not appear at the latest hearing on January 29.

"Mr Mikus asserts that he was wrongly convicted," the Board said in its newly-released reasons for deciding to decline parole.

"He said that he did not commit these crimes and that critical errors were made in relation to the DNA evidence. Accordingly he has not addressed his offending. It is essential that he does so. This was not an isolated incident. He has a history of sex offending against young girls."

Mikus was first convicted of sex crimes as a teenager in the 1970s.

He will have an opportunity for parole at an unspecified future time.
