Several arrests have been made following a mass ride event in Auckland where a large group of dirt bikes and other vehicles were involved.
Counties Manukau road policing manager, Inspector Kay Lane, said police responded to a number of calls on Saturday.
Six people were arrested, and 10 bikes were seized and impounded. A number of infringements were issued.
Lane said further action was likely against those involved, and a number of enquiries were ongoing, with CCTV footage to review.
