Corrections Minister Sam Lotu-Iiga says some of the information provided to him on Serco's running of Mount Eden Prison has not been up to standard.

Under the private contractor, the facility has been the subject of a string of complaints about organised fights, contraband, prisoner injuries and the death of one inmate.
Corrections has appointed a director to manage the day-to-day running of the prison from tomorrow and will impose financial penalties on Serco.
Mr Lotu-Iiga said he was unhappy with the flow of information from his department on the running of the prison.
"I've made it clear that I've been disappointed about some of the communication of reports and other information that could come up the chain through myself and through the chief executive."
Mr Lotu-Iiga expects the situation at Mount Eden Prison to begin to settle with his department in charge from tomorrow.

Australian journalist Antony Lowenstein told Sunday Morning that governments believed they were being efficient by outsourcing prisons or detention centres, but it came at a human cost.
Mr Lowenstein said he has found it was very hard to get information from Serco or governments about their operations, without whistleblowers.
