He was also sentenced to three-and-a-half years on a charge of wilfully attempting to pervert the course of justice, after trying to get an unnamed person to take the rap for the murder.
Retired Detective Inspector Graham Bell and Tauranga Senior Sergeant Lew Warner, who both worked on the homicide inquiry, have described Wilson as one of the worst violent criminals they have dealt with during their lengthy careers in the force.
A spokesperson for the Parole Board told the Bay of Plenty Times Weekend that she could not confirm whether a hearing had taken place and, if one had occurred, it would not be appropriate to comment until the victim's family were informed.
Mr Warner confirmed he had written to the board in relation to Wilson's parole hearing.
