Methamphetamine, cannabis, drug utensils and shotgun cartridges were recovered in raids ''all over town'', including properties in South Dunedin, Brockville and Lookout Point, Detective Sergeant Dave Nelson said.
He confirmed the search warrants were for properties connected to the outlaw motorcycle gang Bandidos, which established a probationary chapter in the city earlier this year.
Five Dunedin people - three male Bandidos and two women who range in age from 23 to 32 - will be appearing in the Dunedin District Court today and Tuesday.
Charges include possessing methamphetamine/cannabis, possessing utensils for the use of methamphetamine, obstruction, dangerous driving and unlawful possession of ammunition.
Det Sgt Nelson confirmed 59 shotgun cartridges were recovered but no firearm.
The charge of obstruction resulted after one man tried to dispose of utensils in his possession, Det Sgt Nelson said.
The charge of dangerous driving related to an incident several weeks ago, he said.
The armed offenders squad was not deployed for the operation.
Inquiries were continuing, with further charges linked to drug offending likely to be laid, he said.
Earlier this year, the Otago Daily Times reported rival Dunedin gang members pledged allegiance to the outlaw motorcycle gang Bandidos after it set up a probationary chapter in the city.
''Bandidos MC New Zealand are excited about welcoming into our Great Red & Gold Nation two new probationary chapters,'' the gang's website said regarding a ceremony held in Invercargill.
That post included photographs of a patching ceremony for the southern probate gang members, which was attended by patched Bandidos members from Australia, Auckland and Christchurch.
Bandidos
Official motto: ''We are the people our parents warned us about''.
Membership: Estimated 2500 members and 210 chapters in 22 countries, including Australia (17 official chapters).
In New Zealand: Probationary chapters in Dunedin and Invercargill; official patched gangs in Auckland, Christchurch, East Coast and Wellington.
