Ouch!

Taking 70 boy-racer cars off the road and 17 arrests in one go must hurt the mob ethos.

There were no major driving incidents and no large gatherings of boy racers conducting illegal activity.

Others got the message very quickly.

the blitz was held to coincide with a car event in the city and involved 70 police staff, as well as court and New Zealand Transport Agency staff

See, there are already laws to deal with this.
