Auckland man Jay Robert Acton, 44, was driving in the other direction in a Volvo V50 from Tauranga on the way to Cambridge.
In findings publicly released today, a coroner found that Acton’s car crossed the centreline into the eastbound lane and the path of the Nissan.
The two vehicles collided head-on, with the right-hand headlight the point of impact for both.
A person in a vehicle following the Nissan witnessed the crash and called 111 before going to help.
Ambulance staff were dispatched but all three people died at the scene.
Acton’s car crossed the centreline as he steered into a long left-hand bend.
A police investigator said this could have been caused by “driver distraction and/or fatigue”.
Associate Coroner Dan Moore said that while these could not be discounted, there was insufficient evidence to make a finding that they were the cause of the crash.
A blood sample showed Acton had traces of alcohol in his system, which might have come from a means other than drinking, and no other drugs of note.
Acton’s Volvo had a worn front left tyre and the Nissan had incorrect wheel nuts but neither factor was considered to have contributed to the crash.
Witnesses said both vehicles appeared to be travelling within the 100km/h limit, and the coroner said speed was also not considered a factor.
“I find that the cause of the motor vehicle incident was driver error on the part of Mr Acton,” Coroner Moore said.
The coroner released two sets of inquest findings today – one for Acton and one for Losaki and Kaimua.
He said that Polokola Kaimua (also known as Polokola Losaki) was not wearing her seatbelt at the time.
“There have been numerous driver safety campaigns stressing the importance of correct and consistent use of seatbelts,” he said.
“There is good reason for this: advice on the Waka Kotahi New Zealand Transport Agency website states that wearing a seatbelt reduces your chances of being killed or injured in a road crash by about 40%.
“I encourage all drivers and passengers to use their seatbelts at all times.”
