Police believe new information on a notorious cold case means they are closer to catching the killer after 30 years.
Chris Bush ran the Red Fox Tavern in Maramarua until he was shot dead in a robbery at the pub on October 24, 1987.
Police at the time understood gang members were among the suspects, and on TVNZ 2's Police 10-7 it was announced that new information had come to light regarding the murder and police were confident it would help them find the offenders.
Detective Inspector Gary Lendrum said police received "credible information" last year from the public regarding the case.
Lendrum said Bush's death "devastated" his family, and he met with Bush's widow Gay and daughters last week.
