Senior Sergeant Ian Campion said there was still a range of factors to consider from the incident and said the coroner's report as to how Mr Baxter died was not yet available.
"At this stage I am not prepared to speculate on what the factors might have been in the crash. I can confirm the west-bound car crossed the centre line." The Kaimai Range was always a high risk area, he said.
"Particularly over the winter months, given the weather the Kaimais often experience which can be heavy rain, through to fog, reduced visibility and ice on some occasions on the summit area so it does flag as a risk for us."
Mr Campion said the Kaimai Range was part of their winter action plan that ran from April 1 to August 31. "It's an area which causes us significant concern and it has improved to be fair.
"There has been an awful lot of work carried out up on the Kaimais around the road surface and road design in terms of engineering and significant enforcement work, the road carries a high volume of traffic and people need to take extreme care up there," he said.
