Four teenage boys have died in a horror crash in Invercargill, says Southland Area Commander Mike Bowman.
Three of the boys were 16 years old and one was 17 years old.
"Yesterday afternoon about four o'clock the Invercargill police and emergency services were called to Queens Drive," Bowman said.
"It involved a Ford Ranger and a concrete truck. Tragically, four young men passed away at the scene."
Three of the young men were from the seaside town of Bluff, south of Invercargill, and it "was a tragedy for the Bluff Community as a whole". It was a small town and the deaths would have a "huge impact".
"Obviously, it's a tragedy for the families of the four deceased young men," Bowman said, his voice shaking. "And we will be working very closely with them."
He added: "No words can explain our sympathy ... to the families and the wider community."
It was still unclear what caused the crash. Bowman said officers would be speaking to a number of witnesses to piece together the events leading up to the collision.
Police were appealing for any witnesses to the lead-up to the crash, and appealed for anyone in the area with dashcam footage to provide it to officers.
Family members visited the site of the crash on Queens Dr this morning.
This would help with the grieving process and give them an understanding of what happened, Bowman said. A blessing was also performed.
Families of the teenage boys killed in the crash were still informing wider whānau of the deaths and police were not ready to name them.
The fatal crash "shook up all the emergency services involved", Bowman said, saying it was traumatic for many who had families themselves.
"It was a horrific scene. But ... our emergency services deal with this unfortunately day-in, day-out."
Bowman thanked members of the public who were first at the scene, while also telling them to "look after yourself" and seek support if needed.
Invercargill Police had called in staff from the broader Southland Region to assist at the crash, which occurred just hours before a fatal stabbing a short distance away.
The truck driver had minor injuries and has been discharged from hospital.
Seconds after the horror crash, members of the public frantically clambered onto the wreckage to try to help.
Footage shared on social media by a witness shows the aftermath of the crash.
The video, uploaded live by a man who got to the scene seconds after the crash, shows the ute crushed under the front of the truck, with people clambering over the wreckage to get to those inside.
The distraught driver of the truck climbs out the window and walks away from the scene in shock.
A group of motorists gathers around the ute and use a crowbar and tools to try to get to those inside the wreck.
"Hang in there mate," one man is heard saying as sirens pierce through the footage.
"The community will rally around those people and give them as much support as possible, because Bluff is a small town," he told RNZ.
Flowers have been left at the police cordon surrounding the crash site.
The wreckage has been removed from the road overnight but the street remains closed.
A note on the flowers reads: "Rest in love boys. For ever grateful to be able to know you all."
The police Serious Crash Unit was at the crash site this morning and more information is expected to be released today about the incident.
Police detective inspector Stuart Harvey said last night that emergency services were called to the two-vehicle crash on Queens Dr, near Queens Park just before 4pm.
A man who lived nearby said he heard "a big bang".
He saw a black four-wheel-drive that had been shunted sideways across the road by a concrete pump truck. The roof of the 4WD was caved in.
There were three men in the truck and they were visibly distressed, the witness said. One was walking up and down the footpath, while the others stayed in the cab.
Nearby residents, and other locals who have travelled past the crash site, earlier posted online about a large number of fire engines, ambulances and police cars at the scene.
A Fire and Emergency NZ spokesman said they had responded to a crash involving a car and a truck. There were people trapped when they arrived and firefighters were still at the scene just after 5.30pm.
A St John spokeswoman said two ambulances and two management personnel attended.
They were only required to assess one person, who did not require transportation to Dunedin Hospital.
When asked about the condition of other vehicle occupants, she referred comment to police.
Last weekend, four people died on New Zealand's roads during the official Easter Weekend holiday road toll period. That was down on nine from 2021.
