A coroner has recommended changes to prisons' record keeping, following the death of an inmate in Christchurch Men's prison.
Murray Childs died the day after he was moved from an at-risk unit into the mainstream prison population.
Coroner Garry Evans concluded the death in October 2005 was self inflicted.
Mr Evans has suggested the system of recording information be reviewed, with a view to amalgamating all information into one system encompassing all aspects of a prisoner's status.
Corrections Department national health manager Bridget White admits mistakes were made, including a failure to consult all Mr Childs' health professionals before he was moved out of the at-risk unit.
She says the Department is reviewing its at-risk procedures.
