He was Kyle Austin Whorrall, a 33-year-old US national.
Police have said two occupants of the erratically driven vehicle attacked him while he was sitting alone at a bus stop on St Johns Rd on Saturday night.
Whorrall was struck with a “long” weapon at around 10pm, suffering multiple head injuries, and later died in hospital.
University of Auckland student Kyle Whorrall was attacked at a bus stop and died later in hospital.
Police say they do not know why Whorrall was at the bus stop, and that he may have been waiting for a bus or sheltering from stormy weather.
Whorrall was based at Manaaki Whenua – Landcare Research, which has an office in St Johns about 3km from where he was attacked. He had nearly completed his PhD.
Police said they had pieced together “snippets” of the incident from witness accounts and video footage from a passing bus and shopping centre.
Whorrall, who lived nearby, had bought groceries at a Woolworths supermarket on Gerard Way about 9.40pm on Saturday, which was part of his usual routine.
He then walked about 400m up St Johns Rd to the bus stop, which took about five or six minutes.
About 9.50pm, a white Toyota ute was cut off by a black SUV that was performing a U-turn. Footage from a passing bus captured an image of Whorrall sitting at the bus stop and the two vehicles.
About 10pm, the SUV parked at the bus stop, facing the wrong direction. Two occupants got out of the car and attacked Whorrall for about 30 seconds before speeding in their car in an easterly direction towards College Rd.
The occupants of the white ute were “critical” witnesses and police were appealing for them to come forward, while emphasising they were not suspects in the investigation. They could be able to confirm how many people were in the black vehicle, or might have captured the car’s number plate.
While footage had been captured of the black SUV, it was not clear enough to identify a number plate. The weapon used by the attackers had not been found.
The hunt for the attackers is now a major police exercise, with detectives called back from holiday to assist.
