The crash happened at 11.05am about 200m from the intersection with Gill Lane.
The sole occupant and driver of a red Nissan received moderate leg injuries and was taken to Tauranga Hospital for treatment, Hunter said.
He said the fatality happened as police were responding to 111 calls from members of the public who reported seeing Hamill's Honda cross the centre line a number of times between Katikati and Tauranga.
A police officer with his patrol car's lights and sirens on desperately tried to get there to intercept the Honda.
Hunter said just before Snodgrass Rd the officer learned that the Honda had crossed the centre line again and crashed into the Nissan.
"One more minute and the officer probably could have got there in time," he said.
SH2 was closed for several hours between Munro Rd and Snodgrass Rd intersections.
