Rob Fitzpatrick's death is one of three involving double bunking at Mt Eden Prison, in just over 12 months.

He was allegedly beaten to death by a man who was accused of attacking someone near a Mangere bus stop.

Corrections Custodial Services Commissioner Leigh Marsh says risk assessments are done for all prisoners - but that is not the answer to the issue.

He says it is more about the processes after they are admitted - because situations are constantly changing.
