A farm worker suffered back injuries after being attacked by a bull near Te Haroto, in Hawke's Bay on Tuesday.
The 24-year-old woman was rescued by the Lowe Corporation Rescue Helicopter after falling down a "shallow hill" while escaping the bull.
"[She] was moving a mob of cattle when a bull turned upon her and knocked her in the back. As a result she tumbled down a shallow hill as part of escaping from the bull," Ian Wilmot, general manager of the Lowe Corporation Rescue Helicopter Service, told Newshub.
"We don't know whether she was kicked or headbutted or whatever."
He said the woman alerted authorities to the incident by activating a personal locator beacon.
"When we got there we found that she had moderate back injuries," he said.
"We transferred her to Hawke's Bay Hospital for further assessment for her injuries."
A spokesperson for the Hawke's Bay District Health Board confirmed the woman was discharged from hospital on Wednesday.
A post on the Lowe Corporation Rescue Helicopter's Facebook page described the incident as a "nasty rural accident".
