A police statement said a further three occupants suffered minor injuries.
Police’s Canterbury prevention manager, Inspector Ash Tabb, told the Herald any road deaths are “devastating” and are “felt by many”.
“Many of the crashes emergency services respond to are preventable. We see too many crashes where motorists have chosen to speed, drink drive, be impatient or let themselves get distracted and take their eyes off of the road,” Tabb said.
“Deaths on our roads not only impact the family and friends of those involved but the emergency services who respond and the public who witness the crash.”
Tabb said the message is simple: “Belt up, keep your speed within the limits and focus on the road in front of you. If you’re having a big night, don’t make the selfish decision to get behind the wheel after you’ve been drinking. Focus on getting home in one piece.”
Police are hoping motorists follow the appropriate safety advice as thousands gear up for the largest motorcycle rally in the southern hemisphere, The Burt Munro Challenge.
The annual motorcycle event runs from February 7 to 11 in and around the Invercargill area and attracts thousands of enthusiasts both riders and spectators from throughout New Zealand and overseas.
The event coincides with Waitangi Day and Lunar New Year celebrations, prompting urgent safety calls from police.
Southland Area Commander Mike Bowman said: “The focus of the operation is to ensure those who are attending the Burt Munro Challenge arrive safely, have a safe and enjoyable time and return home without harm.
“Motorcyclists are vulnerable road users given the much lower levels of protection they have in the event of a crash compared to the occupant of a car.”
