Ten prisoners recently graduated from Whanganui Prison's three month drug treatment programme.
In total 500 prisoners have graduated from the three-month addiction treatment programme, run in conjunction with CareNZ, since it began in 2011.
"Addressing their addiction to drugs and alcohol is an important step in the men's rehabilitation," prison director Reti Pearse said, noting the graduations marked an important milestone for the men and the prison.
"With 500 men having graduated from the programme it is a credit to everyone involved, the men, their mentors, unit staff, and CareNZ.
"The men can look forward to completing their rehabilitation, education and training programmes and return to their whanau and communities with a positive future," he said.
