"At this stage it appears that while the occupants of the car are very seriously injured their situation could have been worse had the logging truck not been going slow up the hill and the driver not quickly reacted to what he saw unfolding.
"The investigation is in its early stages at this point but we can confirm it appears the occupants of the car were visitors from overseas but we need to confirm this with consular officials before we can comment on nationalities."
Earlier this week American man Richard Barnett drove into the path of a truck, killing his wife Tamara and friends Ruth and Mitchell Peterson.
Barnett, 56, was today fined $3000 and ordered to pay $1500 in reparation in the Hamilton District Court after pleading guilty to three counts of careless driving causing death.
The trio were killed on the outskirts of Hamilton on Wednesday night when Barnett turned right at the intersection of State Highway 39 and Tuhikaramea Rd, into the path of a southbound truck.
They were planning to visit the nearby Mormon temple.
In a statement released by his lawyer Thomas Sutcliffe, Barnett wanted to thank the local community for their kindness and support.
"He is grateful for the emergency services who attended the scene and in particular the police who have been compassionate and professional in all of their dealings with him.
"He expresses his thanks for the first class medical treatment he has received during his stay in hospital and the overwhelming support from local church members."
Barnett's son and brother-in-law would be arriving in the country to help with the return of the bodies, Mr Sutcliffe said.
