Five more people have been arrested as police target the Comancheros' motorcycle gang

Four men and a woman face charges of methamphetamine supply and participating in organised criminal groups.

Police say they're not Comancheros, but part of their drug supply network.

Detective Inspector Nicola Reeves says this has significantly disrupted supply into Invercargill and Dunedin.

It follows a Christchurch crackdown on the gang, and brings the total arrests to 31.
