A Government review of police has highlighted the need for victims of crime to be treated better, citing the Roast Busters saga as evidence.
The Performance Improvement Framework review found police had predominantly maintained or improved their standards since the previous report in 2012, though question marks remained around their treatment of victims.
"Public concern regarding the 'Roast Busters' investigation has highlighted the need for police to meet public expectations regarding victim focus and treatment," the review said. "There is still more to be done to reinforce victim focus."
The "Roast Busters" are a group of predominantly West Auckland youths who bragged on the group's Facebook page about having sex with girls as young as 13.
Beraiah Hales and Joseph Parker are alleged to have been the ringleaders of the group, with the pair and several others under watch by police since late-2011 when a 13-year-old made a formal complaint about the youths.
