Police investigating the Roast Busters scandal will seek a legal review of whether charges should be laid.
The Roast Busters were a group of West Auckland teenagers whose videos of them bragging about having sex with under-age girls came to the nation's attention late last year.
It became a national scandal following a number of contradictory statements from police concerning their investigation and the lack of charges laid.
Detective Inspector Karyn Malthus said today that information was being collated to enable a legal review.
"This is a complex investigation and any decision relating to prosecution will not be taken lightly. We are, understandably, working closely with our legal team in this regard," she said.
Malthus said the investigation had a "strong victim-focus".
"The privacy and welfare needs of the young people and their families remains a priority."
She declined to comment further saying the investigation was at a "delicate" stage.
The Independent Police Conduct Authority is reviewing the police response to the case and last month said it had interviewed 11 police staff as well as members of the public.
The review was in its "final stages".
Malthus said the investigation's information line 0800 OP CLOVER was still open for anyone with information.
