A gang convoy has caused disruption to other motorists from Auckland to Waikato - and police are warning the bikies that they face enforcement action.
Police say they are reviewing videos and images that show the gang convoy in Franklin driving dangerously.
Counties Manukau South area commander inspector Joe Hunter said police were aware of a number of gang members travelling south through Counties Manukau towards Port Waikato.
Police said they would be following any unlawful behaviour with enforcement action.
