Stunned schoolchildren watched as a yak attacked a woman on a farm owned by tycoon Alan Gibbs.
Julia Hart, in her 60s, was thrown into the air in front of pupils from Greenhithe Primary School and spent several days in hospital, needing surgery on her elbow.
She was visiting the 400ha farm on Kaipara Harbour for a Christchurch earthquake fundraiser when the 700kg yak attacked.
"He walked slowly over, which I didn't notice, then he put his horn in my groin and huffed me 2m in the air and 2m sideways," said Hart, of Auckland. "I heard a crack. I landed on my elbow with my arm in front of me, and on my ribs. Someone who saw it said it was a classic scene from the cartoons and cowboy movies."
