Asked if he was aware of Handy's background and conviction for arson, Mr Sheppard declined to comment.
Handy said he had not disclosed his conviction when he joined the force. "It didn't come up," he said. "I didn't think it was necessary to tell anyone."
Asked if he thought an arson conviction might have relevance to his firefighting ambitions, Handy said: "People change. And I've changed."
Handy, then aged 19, was sentenced in the Christchurch District Court in August 2007 to two years' jail on two charges of unlawful sexual connection, burglary, theft of a vehicle and arson.
He had been found guilty at a jury trial on the sex charges, which involved a 14-year-old schoolgirl, and admitted the others. The arson charge related to stealing a truck and setting it alight.
