Four people were arrested during a street racer event in the Hutt Valley at the weekend.
Police went to Petone to prevent a group setting up a skid pad around 10pm on Saturday.
About 10 vehicles at the location were stopped and spoken to, and several infringement notices and non-operation orders were issued.
Police were then made aware of other members of the group starting to gather at a location on Eastern Hutt Road, and about 100 vehicles were found at the site.
Police stopped and checked all vehicles attempting to leave the area, and several more infringement notices and non-operation orders were issued.
In total, 39 infringement notices were issued, five vehicles were either pink or green-stickered, two vehicles were searched for drugs, and four people were arrested.
Relieving Hutt Valley area commander Inspector Simon De Wit said he knew how disruptive it was for residents, and had seen previous examples of how dangerous such meets could be.
Police were committed to bringing these activities to a halt and holding those responsible to account, he said.
