Police are urging all road users across Tasman Police District to take extreme care this weekend as the district experiences an influx of motorcycles on the TT2000 endurance ride.
About 100 riders will depart from Woodbourne in Marlborough and also from Bunnythorpe in the North Island, trying to reach a wide range of checkpoints in the district as part of the annual endurance ride, before heading to Christchurch.
Tasman District Road Policing Manager Inspector Jenni Richardson said Police had been working closely with the event organiser to ensure riders taking part in the event were safe and rode within the law.
"Riders are aware that Police will be monitoring their behaviour and that there will be no tolerance towards speeding or risk-taking behaviour on the roads."
Inspector Richardson said one rider taking part in the event was killed travelling through Golden Downs in 2010.
"That's really made us and the event organisers take a close look at how things are run and we're hoping that this will be an enjoyable weekend out for participants and that everyone gets home safely."
The endurance ride covers 2000 kms over a 48 hour period, ending in Chrstchurch at 6pm on Sunday.
