The chartered accountant at Lyndsay Tait & Associates said there are three types of people in the world.
"Type one: see something that shouldn't happen and think someone should do something about that. Type two: see something that shouldn't happen and do something about it. And type three: play oblivious."
Ms Pearce said she wanted to become a JP because she sees herself as type two.
In order to meet the regulations of becoming a JP, the nominee needed to have been active in the community.
Ms Pearce has been a financial advisor for Hockey Wanganui for many years and has been heavily involved with Wanganui City Football Club.
