A motorist who died after the vehicle he was driving veered off the road and rolled across a paddock may not have been wearing a seat belt.
The latest road fatality happened on State Highway 1 just south of Okaihau next to Lake Omapere about 7.10am on Saturday.
It has pushed Northland's road death toll so far this year to 34, compared to 27 in 2016 and 22 in 2015.
Twenty of the people killed this year have been in the mid and Far North, with four of them pedestrians.
Saturday's crash happened a day after Northland's top road cop, Inspector Wayne Ewers, warned motorists to heed the safety messages and who said yesterday it was "absolutely frustrating" to hear of another fatality.
He said early indications showed the driver of the car in the Okaihau crash was not wearing a seat belt as he was thrown out when the car rolled.
Okaihau fire chief Andrew Graham said the crash happened at the end of a straight road going into a corner.
He said the car veered off the opposite lane and rolled across a paddock about 50m from the road.
Fire appliances from Okaihau and Kaikohe attended.
Traffic was not disrupted as the car ended up off the road.
Police were not ready to release the name of the driver or of a male pedestrian who was hit by a car on Friday morning.
He was among two men and a woman who were walking on Awanui Straight, SH1 between Kaitaia and Awanui, after their car broke down when they were hit by a passing vehicle.
Mr Ewers said safety messages were still not heeded by a small number of motorists.
"Driving is a serious business when you treat it as such. It's all about taking your time, not overtaking in wrong places, and not making irrational decisions because it can be fatal.
"These fatalities are absolutely frustrating. Our message is the same. Obey the road rules, don't drink and drive, always wear your seat belts, don't speed and you'll get there safely," he said.
Mr Ewers emphasised the importance of wearing seat belts.
"People think they're just ducking around the corner so they don't need to be wearing them. It should be, hop into the car, put your seat belt on, start the engine and off you go and not the other way around."
Meanwhile, no one was hurt when a car and a motorcycle collided on SH1 just south of Kawakawa yesterday morning.
Passing motorists stopped to assist the motorcycle rider who appeared to be fine.
