A man with name suppression and Mark Joseph Hoggart have been on trial in the High Court at Auckland for seven weeks.
The widow of slain Red Fox Tavern publican Christopher Bush has welcomed a "sense of relief and justice" after the two culprits were jailed for life.
Gaye Bush said today's sentencing brought an end to a "painful chapter" of her life, 33 years after the murder.
"Having some closure afterall these years brings about a sense of relief and justice for the family and it is now time to move forward and put this painful chapter behind us," she said.
Mark Joseph Hoggart and a second man with name suppression were found guilty in March of aggravated robbery and the murder of father-of-two Bush.
The law requires the men be sentenced according to penalties available in 1987, when the murder happened.
"The one positive that's uniformly expressed in the victim impact statements is that after this enormous passage of time, this matter was brought to trial and this verdict delivered."
One person who presented a victim impact statement said the guilty verdicts provided closure for the family and for the north Waikato town.
Hoggart appeared to acknowledge a supporter when he entered the courtroom.
Both men were silent and motionless when asked if they wanted to say anything before sentencing.
The Crown said even if the shooting was not planned in advance, it could not be deemed an accidental or even reckless shooting.
"This case continues to throw up unusual and somewhat complicated issues," said Christopher Stevenson, defence lawyer for the man with name suppression.
He said the shooting was "a reflexive action" and his client maintained his innocence.
The shooter retains name suppression until he decides whether or not to lodge an appeal.
Stevenson said a lesser penalty for murder was available in 1987, and though a life sentence then could've been imposed, there would have been no minimum jail term.
"It is a highly unusual case," Hoggart's defence counsel Craig Tuck said.
"And in relation to Mr Hoggart, less culpability can be attributed."
Hoggart was armed with a baseball bat and his accomplice with the shotgun.
Justice Mark Woolford said Bush was shot at the tavern after throwing a half-pint glass at the robber with the shotgun.
The publican was shot from a distance of three to five metres, the judge said.
"Mr Bush's injuries were unsurvivable. He died within a minute."
The court was told the man who shot Bush was also in his 60s now and had a previous conviction for aggravated robbery.
Manukau's Crown solicitor Natalie Walker and Ned Fletcher led the prosecution.
Relief for town after tragedy
Today, Detective Senior Sergeant Mike Hayward of Counties Manukau police said the guilty verdicts had brought huge relief to Bush's family and to Maramarua.
He said the members of the Bush family he'd spoken to were elated today.
"No family should have to endure 33 years for justice."
Hayward said he hoped former bar staff would also take comfort from the life sentences imposed.
And he paid tribute to police who worked on two earlier investigations decades ago.
"The work the initial investigators did back in 1987 and 1999, this whole case to date has been based on the foundations by those guys."
He made a special mention of Detective Inspector Gary Lendrum, who died of cancer in December aged 62.
It was Lendrum who inspired a re-investigation of the case when the 30th anniversary of Bush's death approached in 2003.
