The man convicted of murdering Timaru woman Lisa Blakie has been again denied parole.
Timothy David Taylor was in 2000 convicted of the murder of Ms Blakie, whose body was found stabbed and strangled in an Arthur's Pass river on Waitangi Day.
Taylor admits he gave Ms Blakie a lift but denies murdering her.
In a January parole board decision released today, Taylor was again denied early release from his life sentence for the killing.
The parole board said Taylor had a "very significant way to go before he could be eligible for release".
"He is described in the psychologist's report as being of high risk of general offending involving criminal attitudes, violence, substance abuse and gang relationships," it said.
Taylor had a significant criminal history, including the rape of a woman in 1986, the board said.
It found he had not told the board about an attempt to introduce contraband into prison during his last parole hearing in early 2015.
His next chance at parole will be in December.
In a previous parole decision, the board highlighted Taylor's "manipulative behaviour" while in prison.
He had alleged other prisoners intimidated and tried to blackmail him, but felt he could not raise the issue with prison staff.
Instead, he smoked cannabis "with a view to being picked up on a random drug test, thereby leading to his removal from the unit", the Parole Board said in 2013.
