Rehabilitation charity Freedom for Life says spending more money on resettling prisoners in Jersey would lead to long term savings.
They say that extra expenditure on prisoners after they leave jail could lave long-term benefits.
The comments come after a report revealed that more than half of Jersey's inmates at La Moye have been in prison before.
The figures showed that 154 out of the 260 people sent to prison in the last year had previously served time.
Kevin Houiellebecq, from the Freedom for Life charity, says that spending extra money on rehabilitation could save the taxpayer in the longterm.
