A police spokesperson said they were aware of a group of motorbikes travelling through Auckland.

“The group will be monitored and police will respond to any incidents that may arise,” they said.

The group were seen riding along State Highway 20 and State Highway 16 towards the city.

This comes as police crackdown on illegal dirt bike riding this weekend got underway.

Operation Metallic Red focuses on targeting dangerous and nuisance driving and the riding of dirt bikes across the Manukau district.

Counties Manukau Police senior sergeant Anton Maisey said in an earlier statement that police will be visible on Sunday and Monday, particularly in the South Auckland area.

“Police and the wider community have zero tolerance for this dangerous driving that puts other motorists and members of the public at risk.

“These riders show a complete disregard for others.”

One goal of the new operation is to prevent dirt bike activity from growing into larger gatherings where police said they have seen reckless behaviour emerge in the past.

“Any offending will be investigated and follow-up action taken.

“Police have held riders to account in the past and we will continue to utilise all available avenues around enforcement.”

Police said this enforcement could include impounding vehicles, infringements, or arrests for any driving offences.

Anyone who observes dangerous or nuisance driving as it is occurring can contact 111, or alternatively the 105 phone service, or anonymously via Crime Stoppers on 0800 555 111.
