A woman was injured when she was thrown from the back of a ute doing donuts on a beach.
The Westpac Rescue Helicopter was called to the incident on Karioitahi Beach, near Port Waikato, at 5.30pm on Friday.
Helicopter manager Greg Brownson said the woman had been riding on the back of a ute when she was thrown off onto sand.
He said it appeared the vehicle had been doing donuts on the beach.
"When we got there you could see the donuts [tracks] all the way up the beach," he said.
