Hawke's Bay police are preparing for the worst as car enthusiasts from around the country gather in the area this weekend.
Police were made aware of the meeting via social media and Eastern District Road Policing Manager, Inspector Matt Broderick, said they had no issues with them gathering safely but officers wanted to have precautions in place.
"Unfortunately past experience has shown that these events often result in a number of offences that put other innocent road users at risk," Mr Broderick said.
"They often included high speed and unsafe driving, illegal racing, impaired driving and unsafe modified vehicles that should not be on the road."
There would be a high visual police presence to ensure drivers and their vehicles would be safe on the roads.
