The non-emergency positions will help with St John's patient transport service and require as little as four to eight hours a week commitment, with no weekends.
Volunteer member services manager Kate Fina said the new roles were also physically less demanding.

"Duties will range from moving a patient from a hospital ward for transfer by ambulance and accompanying people to their medical appointments."
