Hawke’s Bay’s road toll for 2023 was 17 deaths, the same figure for all of 2022.
National Road Policing Centre director Superintendent Steve Greally earlier told Hawke’s Bay Today that the main cause of deaths and serious injuries on roads typically included speed, alcohol, drugs, distraction and unrestrained drivers and passengers.
“Road safety is something we all have to take a greater responsibility for,” Greally said.
He said police patrols would be highly visible over the holiday period.
A total of 18 people have been killed on New Zealand roads this holiday period.
Meanwhile one person was taken to hospital after a crash on Ormond Rd at 12.15am on December 30 in which they sustained critical injuries.
The second person was taken to hospital with critical injuries after a two-vehicle crash on State Highway 50 and Maraekakaho Rd.
No updated conditions were immediately available for these two motorists.
