A 20-year-old Hamilton man, Izzaic Hauwaho, lost his bid for suppression.
His lawyer, Charles Bean, applied for bail on his behalf but that was also refused by Judge Saunders.
Hauwaho entered not guilty pleas to his 25 charges and was remanded in custody to reappear in August for a case review hearing.
Operation Trojan Shield has been led by the FBI which developed a phone sting that successfully spied on some of the world's most ruthless gangs through their own fake phone and encrypted messaging service, Anom.
The operation was carried out over five years and in New Zealand saw senior members of the Comancheros, Mongrel Mob and Head Hunters gangs arrested.
