Hurt cyclist wasn't wearing helmet

A 13-year-old cyclist who was flown to hospital with head injuries was not wearing a helmet, police say.

After being struck by a car in Carterton yesterday afternoon, the boy was taken to Wellington Hospital in a Life Flight Westpac rescue helicopter with head and leg injuries described as "serious" .

The young cyclist was hit on Park Road in Carterton at about 1pm and was initially cared for by Wellington Free Ambulance paramedics at the scene, police said.

The Wellington-based Serious Crash Unit was investigating the cause of the crash but neither speed nor alcohol was thought to be a factor, Wairarapa police senior sergeant Jymahl Glassey said.

"He was with another boy on a bike [and] drifted into the path of the vehicle."

Mr Glassey said he had been told the boy was in a lot better condition than yesterday and his injuries were not life threatening.

"But it's caused him some grief by not wearing a helmet and [a helmet] would have definitely taken some of the force of the impact."
