The National Organised Crime Group Investigation named Operation Samson investigated a number of residential and commercial properties across Auckland linked to the New Zealand chapter of the Hells Angels.
A 30-year-old Hells Angel member was charged with money laundering and has appeared in the Auckland District Court.
Detective inspector Albie Alexander said this type of offending undermines the well-being of communities.
He said the investigation would continue to target those who accumulated assets and wealth through illegal means.
