At the time of the offending, Kirkpatrick was the vicar at St Michael and All Angels in Christchurch.
He would later go on to be dean at St Paul’s Cathedral in Dunedin for five years until 2001.
Kirkpatrick was jailed for more than three years in 2011 for stealing more than $665,000 from Auckland University of Technology, where he had worked as chief executive of its Business Innovation Centre.
He remains in custody before sentencing for the sexual assault.
A jury unanimously found him guilty last Friday after a week-long trial.
The victim, who was about 18 at the time of the attack, told the jury that when he was a teenager he would regularly meet with Kirkpatrick after school to smoke marijuana at his house.
The victim knew Kirkpatrick was gay but had no concerns his motivations were sexual until the night of the attack.
The pair drank alcohol and smoked cannabis at Kirkpatrick’s bach in Lake Coleridge on the night of the attack.
The younger man said he became so intoxicated he was put to bed by Kirkpatrick, but woke to find the then-priest violating him.
The victim did not report the assault to police until 2020.
Prosecutor Penny Brown said by that time the man’s life had derailed and he was due to be sentenced for serious offending of his own.
The victim said he had decided to report the assault after he encountered people in prison who had also been abused and had benefited from talking to others.
