A New Zealand woman killed in a Contiki van crash in Indonesia on Thursday worked for the tour company.
The woman, who has not been named, was one of three New Zealanders involved in the crash.
Two others, including 29-year-old Christchurch woman Abbey Moore, were injured.
Director of Contiki NZ Mark Turner said 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," he said.
"Here in New Zealand we are doing everything possible to support families, directly affected clients and our people during this difficult time.
"This includes having spoken with and providing assistance to our colleague's parents as well as the parents of the two New Zealanders who were injured in the crash.
"We offer our deepest condolences to her family - our heartfelt thoughts are with them.
The van the New Zealanders were travelling in was heading to a surf beach in Lombok when it went over a cliff, rolling several times.
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.
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."
Abbey's friend was in the tour van behind the one that crashed and witnessed it go off the cliff.
"She saw it all happen which was not very nice for her at all."
McConchie said her daughter sounded "very groggy" on the phone and she still did not know the full extent of her injuries.
She did not know if her daughter would be transported to Bali, or directly to Australia or New Zealand.
"If she stays there we will go over but she is being cared for very well by her friend who is travelling with her who is a nurse."
McConchie said she had received good support from the Contiki tour company and the New Zealand Consulate.
She said she did not know if her daughter knew the New Zealander who had died.
"Abbey and her friend had just joined the tour so I'm not sure if they knew the person," McConchie said.
"All I can say is, it is very sad."
