Trio killed in Diwali horror crash named

The three people killed in a horror Diwali crash in Takanini on Sunday night have been named.

The newlywed couple and brother-in-law died after the car they were in lost control at a roundabout on Great South Road, came off the road and tore through an Auckland BurgerFuel restaurant.

RNZ understands the vehicle is believed to have been travelling at more than 150 km/h.

Daljit Singh, spokesperson for the Supreme Sikh Society, confirmed the victims were Sukhdeep Singh, 33, his 29-year-old wife, Sukhvir Kaur, and brother-in-law Gurpreet Singh, 38.

Sukhdeep had lived in New Zealand for seven years, Daljit said, while Sukhvir had arrived six months ago.

Gurpreet, who had a young son and wife in India, had called Aotearoa home for three years and worked as a courier driver for New Zealand Post.

Daljit said it was a "huge tragedy".

"They were actually celebrating Diwali at the Manurewa Gurudwara, where they were coming from when this incident was happened," he said, adding that the circumstances of the crash were unclear.

"I'm actually in regular touch with the police and we're talking to them almost every two or three hours, but so far, about the investigations, they haven't actually released any information because they still interviewing some other people as well ... we know that they've been to their employer ... but just waiting for their outcome."

Emergency services were called to the crash just after 10:15pm on Sunday night.

All three occupants were pronounced dead at the scene, police said. No one inside the building was injured.
