He has been accused of organising drug runs for a methamphetamine ring and accessing the police computer system to tip off colleagues in the Head Hunters gang.
Eight others have also been arrested in relation to the alleged enterprise.
Pakau, a father of five, was allegedly linked to two methamphetamine cooks whom he organised to manufacture the drug, which he would then take in ``substantial amounts'' to his dealer or supplier, according to a police summary of facts.
"His role was significant because he was accessing the police computer system,'' said Crown prosecutor Brett Tantrum at the officer's first court appearance.
Pakau is also charged with conspiring to defeat the course of justice on three occasions and theft of a vehicle.
He declined to comment when approached outside court today.
