The cow that attacked two people in a south Auckland park has been put down, along with its eight-month old calf.
Cliff McMahon intervened when a woman was attacked by a protective herd in Totara Park, yesterday afternoon.
McMahon this afternoon remained in Middlemore Hospital after being trampled.
The animals were allowed to roam near the park's recreational trails and farm manager Peter Linton said there had only ever been one other confrontation in the past 18 years.
He said, in that case, the animal was antagonised.
