Police are condemning a motorcycle rally where drivers are encouraged to travel 2000km through the South Island over 48 hours.
A Tasman District Police spokeswoman says the TT2000 South Island event set to be held this weekend encourages dangerous driving.
The event challengers riders to visit 150 locations covering 2000km across the South Island.
Road policing manager Inspector Jenni Richardson says while the event organisers have warned drivers about speed and fatigue there was no doubt the TT2000 was a race.
"This event promotes everything we're against in road policing," she says.
"Riders are encouraged to cover extreme distances on winding and remote roads over one weekend.
"I have no doubt that there will be extremely fatigued riders travelling at excessive speeds all over the South Island."
She says a driver participating in the event in Golden Downs, near Nelson, was killed two years ago.
"Make no mistake, we will be targeting riders taking part in this race. The underlying motivation behind this event is in my view a recipe for disaster."
Event organiser Mike Ryan told NZ Newswire said police had been complaining about the event for a number of years and he did not want to comment.
