Trail bike riders in the Fordlands area breaking the law are again causing grief for Rotorua police.
Rotorua police acting area controller Inspector Brendon Keenan said the riders were usually doing one or a combination of illegal activities, including riding stolen bikes, speeding, riding on reserves or not wearing helmets.
In the past police said they had information those riding trail bikes were delivering drugs.
Keenan said they didn't have any new information to suggest that was still the case but they wanted the opportunity to stop the riders to find out.
