A former Corrections officer says she was threatened with the sack when she spoke up about widespread corruption at Rimutaka Prison.
A three-year police investigation into the jail has this week led to six people facing charges of corruption and bribery, including one prisoner, a current employee, three former workers and a member of the public.
Corrections says the illegal activity is limited to a small group, but our reporter Soumya Bhamidipati has spoken to a former guard at the prison, she spoke on condition of anonymity, who says the behaviour is widespread.
Soumya spoke to Charlotte Cook.
