Police have fought back after an organised boy racer meet-up in Christchurch on Friday night.
Up to 5000 people could have turned up to the "Aves Invasion" event, but according to police only a little over 100 were there on the night.

Several officers were in the area and police say enforcement was taken where offences were noticed. Police could not confirm at this stage how many tickets were given out.
Videos posted to the event's Facebook page show cars doing burnouts in the middle of the road as spectators crowd around.
Posts also suggest the racers played cat and mouse with police, moving to a different spot when officers arrived.
Canterbury Road Policing Inspector Ashley Tabb said police will continue to keep an eye out for illegal behaviour from motorists.
"Police understand that some young men and women love their cars," he said.
"They represent freedom, status and good times. But it can all go very wrong when their love affair with the car starts impinging on other people.
"Police have no tolerance for this type of behaviour and people who use public places as race-tracks. So think very carefully if you don't want to lose your licence or your vehicle. Nobody likes anti-social road-users."
Insp Tabb encouraged the public to come forward and complain if they are affected by any illegal driving activity.
According to the Facebook event a second night of the "Aves Invasion" is planned for Saturday.
