Officers also carried out 80 breath tests, that netted three drivers for driving with excess breath alcohol levels and two for driving while disqualified.
Police said one driver was charged with illegal acceleration.
All six offenders are due to appear in the Whangārei District Court.
Overall, 48 infringement notices were dished out for offences such as underage drinking and breaching licence conditions.
Senior Sergeant Stephanie Hudson, Whangārei/Kaipara Road Policing Services team leader, said the focus was not only on dangerous and illegal driving but also compliance with driver licence conditions and vehicle safety standards.
“It’s about educating these drivers on what modifications are legal and those that make the vehicles unsafe for them as well as other road users,” she said.
Hudson noted a noticeable increase in the number of young drivers with modified vehicles engaging in anti-social and dangerous driving behaviours.
The public was clearly getting sick and tired of cars racing around, she said.
“We won’t tolerate the anti-social behaviour on our roads and we will continue to target people who are intent on offending.”
Hudson warned police will continue to crackdown on motorists whose driving puts themselves at others at risk.
