A Hawke's Bay teenager is in a serious condition on Monday in Hutt Hospital after being kicked in the head by a horse.

Lauren Dolan, 18, had been at a one day horse event near Takapau on Sunday when the incident occurred.

Event organiser Anna Murphy said Dolan had been warming up on her horse when she was apparently bucked off, and hit in the head by the horse's hoof as she fell.

"The witnesses said she fell from her horse whilst warming up, she wasn't competing.

"As she fell, I believe she was kicked to the head area," Murphy said.

"As soon as it happened the medics were called and they were on site.

"A paramedic who is an ICU specialist attended to her until the rescue helicopter came."

Dolan was flown to Hawke's Bay Regional Hospital with head injuries and then later transferred to Hutt Hospital for further treatment.

She is currently in "a stable but serious condition," a spokeswoman said.
