Corrections Minister Judith Collins is rejecting claims that "fight clubs" have been in prisons since 2009, when she was last minister.
Private prison operator Serco revealed yesterday that there were two previous investigations into organised violence at Mt Eden Corrections Facility (MECF) in 2014 and the old prison at Mt Eden in 2009.
The company is seeking a revision of a new investigation into "fight clubs" at MECF, saying that it ignored these past two inquiries - one of which took place under Ms Collins' watch.
