During the expo, the employers and prisoners were split into two groups, with one group having face-to-face job interviews while the other group went with the prison industry instructors to see the industries.
Pearse said the employers were really positive about the way the men were prepared for interviews and interacted with them.
"To meet and talk with the men in our care in their work environment was seen as a very real-life situation that gave employers an understanding of what employment offers for skills and work ethic development, teamwork experience and training."
As a result of the expo, seven men were offered jobs with Whitakers, Taranaki Pine, Gas and Plumbing, Traffic Safe and Naki Labour Hire.
Five of the offers are for "release to work" where the men will spend the day with their employer and then return to the prison. The other two job offers are post-release.
Due to the success of the expo, Pearse hopes it will continue in the future.
"The potential for positive change is enormously encouraging," he said.
