Police made an arrest and located numerous items of interest during an operation against the Head Hunters gang in West Auckland Friday morning.
Search warrants got under way early this morning at properties on View Road and Cranwell Street in Henderson as part of Operation Cobalt, police said.
The team were assisted by members of the Armed Offenders Squad, Waitematā District staff and road policing.
One arrest was made after police located various quantities of methamphetamine and cocaine.
"At one of the addresses, a patched member of the Head Hunters was arrested for possession of methamphetamine," Acting Detective Inspector Tim Williams said.
Three motorcycles were also impounded at the property on View Road.
"Police impounded these motorcycles as part of an investigation into previous traffic offending," Williams said.
"We are continuing to investigate the range of prohibited drugs located this morning and we can't rule out further arrests or charges being laid."
A 52-year-old man is expected in the Waitākere District Court on 29 June.
No further issues were reported from checkpoints set up in the area, Williams said.
"Today's search warrants are yet further action being taken against unlawful activity being committed by gangs under Operation Cobalt.
"We have no tolerance for this offending, and police will continue to disrupt this activity and hold offenders to account."
