Dilpreet Singh, Pulkit Malhotra, Imad Dib and Syed Haris Jafri were travelling along the beach in a Mitsubishi Pajero when it rolled over on Sunday. The men were killed after they were thrown out of the vehicle in the crash, the New Zealand Herald reported on Monday citing police.
"The fact that the occupants have all been ejected from the vehicle would suggest that they may not have been wearing seatbelts, but this will be confirmed once the car has been examined" Inspector Trevor Beggs was quoted as saying.
Beggs added that based on witness information, police believed the car was travelling at speed along the water's edge.
"It's either struck an object or has hit sand. The vehicle has then flipped and rolled several times," he said.
Singh, Dib and Jafri had been working at Auckland's Queens Academic Group for the past one year, while Malhotra had recently arrived as a tourist.
