The death of a man injured in a crash in Waikato yesterday has brought the holiday road toll to 10.
Sean Coe, 20, died of his injuries about 4pm today in Waikato Hospital.
Mr Coe was in a car which appeared to have lost control and crossed the centre line, colliding with a van carrying five disabled children on State Highway 1 at Horotiu, north of Hamilton, about 8.30am, Acting Waikato road policing manager Senior Sergeant Jeff Penno said.
Speed, alcohol and driver fatigue all appeared to be factors, he said.
Another man in the car was seriously injured.
The van driver suffered minor injuries and the children were shaken by the ordeal.
Shortly before 1pm today a motorcyclist died after the bike he was riding and another motorcyclist collided head-on on SH25, which crosses the bottom of the Coromandel peninsula, closing the road for several hours.
The men had been negotiating a series of S-bends on Whangapoa Rd, between Coromandel and Te Rerenga.
The other rider was seriously injured and had been flown to Auckland hospital by helicopter, Mr Penno said.
Police were still investigating the cause of the crash.
Mr Penno said motorists were injured in two other crashes today and, with perfect weather, none had been accidents.
They all could have been avoided if drivers had watched their speed, kept left, avoided drinking and worn seatbelts, he said.
"What we're seeing is people becoming impatient and not driving to the conditions, if traffic flows at peak times are going to be greater than normal, and they are over the holiday period, then you need to plan your trip accordingly and consider leaving earlier to avoid any hassle."
The official holiday road toll period started at 4pm on Christmas Eve and runs until 6am on Wednesday. Last year, 13 people died on the roads during the period.
Police have named a 13-year-old girl killed after the car she was in and a truck collided about 3pm, Friday on State Highway 2 at Whirinaki, 14km north of Napier.
She was Tanisha Morris, from Napier.
The car she was in was travelling in a line of traffic when the first vehicle slowed to turn into a driveway, Senior Sergeant Fred van Duuren of Napier police said.
"The next vehicle did the same but it seems like the vehicle in which the deceased was a passenger in didn't and had to swerve and swerved into the path of an oncoming truck," he told NZPA.
Police today named a 35-year-old driver who died in a single car crash just south of Hastings about 1.45pm yesterday.
