A man who live-streamed the graphic aftermath of the Invercargill crash which claimed the lives of four teens only removed the footage when police stepped in.
The crash claimed the lives of Konnor Steele, Indaka Rouse, Kyah Kennedy, all 16 and of Bluff, and 17-year-old O Maruhuatau Otuwhare Tawhai, of Invercargill, when the Ford Ranger they were in collided with a truck on Queens Drive on Friday.
As emergency services rushed to the scene a man, who parked 10m away from the wreckage, took out his cellphone and began to live-stream to Facebook.
The resulting footage showed him first observing before he became involved in efforts to get inside the damaged vehicle.
He told the Otago Daily Times he had been unaware of the severity of the crash and tucked the phone in his pocket to continue filming, capturing harrowing images of the victims.
The video remained online until early the following day.
The witness said he eventually deleted it "to respect the families and those young kids" but later admitted it had been removed at the request of police.
A former Invercargill resident, who spoke on condition of anonymity, said she came across the disturbing film on the man's Facebook profile while reading the comments attached to an online news report.
While the video may have been traumatic if viewed by the family members of the teens, she said it could not be prosecuted under the Harmful Digital Communications Act since it required proof of an intent to cause harm.
Rather, it was more likely a breach of the tort of privacy, Dalziel said.
While the original video had been removed from online there remained the potential it had been uploaded by others.
"We urge anyone who has shared it since it was originally posted to delete it immediately," police said.
