No charges were laid as a result of Operation Clover, however, the police announced in October 2014.
Six years later, the Herald can reveal three men face charges.
In a statement, Detective Inspector John Sutton said Waitemata Police received a formal complaint from an individual earlier this year in relation to alleged sexual offending involving three males in 2013.
"As a result of Police's investigation into this complaint, charges will be filed against three men of sexual connection with a person aged 12-16."
Sutton said two 24-year-old men will appear in the Waitakere District Court on 23 December 2020.
"A warrant to arrest will be sought for a third man, who currently resides overseas. That person will be arrested if he returns to New Zealand," said Sutton
"As the matter is before the courts, Police are not in a position to comment further."
The prosecution comes five years after a report by the Independent Police Conduct Authority which identified failures in how the police originally investigated complaints and concerns about the 'Roast Busters' dating back to 2011.
