One person has died and another is critically injured after a car crash near Queenstown, while a third person was also seriously hurt in the region when a vehicle was crushed by a truck.
Police are calling for witnesses to come forward after the crash on Kingston Road (State Highway 6) last night.
The crash involved two vehicles at Jack's Point about 6.10pm. One person died following the crash and a second person was airlifted to Christchurch Hospital in a critical condition.
"As part of our enquiries into the circumstances of the crash, we would like to hear from anyone who witnessed the crash, as well as anyone who may have relevant dashcam footage."
"Emergency services were at the scene late last night. A photographer at the scene said the crash involved a sedan and a ute.
The roof of one of the vehicles had been taken off, with two ambulances at the scene treating patients.
A rescue chopper was also at the site of the crash along with two fire trucks and two fire support vehicles, the photographer said.
Earlier, a person was seriously hurt about 4.40pm after being "trapped between a rolling truck and a shed" at a property on Kinloch Rd, near Glenorchy.
"The person reportedly had serious injuries and was being transported to hospital by helicopter," a police spokesperson said.
The Easter long weekend injuries in the South Island follow a fatal accident in Auckland last night, when a passenger in a car fleeing police died in a crash.
That incident started when police stopped a suspicious car at 10.07pm on Clevedon Rd in Papakura to make inquiries with the driver but the car instead accelerated away.
Police did not start a pursuit.
Several minutes later the vehicle was located by another police unit after it had crashed into a pole at the intersection of Porchester Rd and Walters Rd, Takanini.
"The driver fled the scene and police immediately rendered medical assistance to the two remaining occupants of the vehicle," police said.
"Sadly, one of the passengers died at the scene."
A second passenger sustained serious injuries.
The driver of the vehicle was located a short time later and had sustained moderate injuries.
"This is a devastating event for everyone involved," said Counties Manukau District Commander Superintendent Jill Rogers.
