The sister of an Indian national - one of three killed in a car crash in on Desert Road on Monday - says she still can't believe her "amazing friend" is dead.

Police have named Arshpreet Kaur Sidhu, a 23-year-old woman in New Zealand on a working visa, as one of the three who died in the collision with a truck.

She was a backseat passenger along with Monalisa Alofaifo, a 20-year-old Samoan woman with New Zealand residency.

Twinkle Ansal, a 21-year-old man from India on a student visa, was in the front passenger seat.

In an emotional Facebook post, Ms Sidhu's sister Joban says she's still coming to terms with what happened.

"Walking towards to morgue hoping that the body I am Identifying won't be yours.

"Seeing you lying down on bed cold and calm hoping that you will just get up and say I was just joking Di."

She was remembered as "a great sister and an amazing friend".

"A beautiful person with a beautiful heart and great soul who cared about whole world."

Meanwhile the driver, a second 21-year-old Indian man on a working visa, is in Waikato Hospital in a critical condition.

Police say the car was travelling north and appears to have crossed the centre line and into the path of an oncoming truck.

The truck driver was uninjured.
