A 23-year-old Takapuna woman has been identified as the Kiwi who died when a Contiki minivan crashed off a cliff in South Lombok.

Danielle Angus' grieving family have flown to Indonesia to bring her body home to New Zealand, Fairfax reported.

The young Contiki staff member was one of three Kiwis in a group of seven travellers on board the van when it went over a cliff and rolled several times on the way to a surf beach in Lombok.

Emergency services spent an hour trying to free the New Zealanders from the van which had plunged into a riverbed.

Lombok International Medical Service's Dr Caahuua said two of those in the van, the New Zealand woman killed and an American tourist, were taken to the service.

"The car has slipped on a hill and [gone] into the river. The people helped get the people out of the car. Many people were helping."

The New Zealand woman was taken by ambulance to the medical service, but was "dead on arrival", he said.

Director of Contiki NZ Mark Turner told the Herald he was "deeply saddened" to confirm that a client was killed in the accident.

"She was also one of our valued colleagues at our Auckland office and naturally we are devastated at losing a friend and colleague."

The company had spoken with the dead woman's parents as well as the parents of two other New Zealanders injured in the crash, he said.

"We offer our deepest condolences to her family - our heartfelt thoughts are with them."

Turner said the three clients injured were receiving treatment in hospital.

"It is our understanding that their injuries are not life-threatening," Turner said.

"Senior company representatives have travelled to Indonesia and are supporting those in hospital to ensure they are receiving the best possible treatment.

"They are also providing support to the other clients on the tour."

Injured woman Abbey Moore was in hospital in Lombok with a dislocated shoulder, a broken wrist and collarbone and suspected broken ribs.

Her mother Rose McConchie told the Herald she spoke to her daughter over the phone yesterday was relieved she wasn't more seriously injured or killed.

"It seems like she was very lucky to have escaped with the injuries she has," her mother said.

"She was very lucky she wasn't killed."
