DOC Hawke's Bay operations manager Connie Norgate says the death of this bird was unnecessary.
"At no stage should people shoot these birds," she says.
Not only is the kārearea New Zealand's only falcon, it is the nation's most threatened bird of prey, with its population estimated to be at fewer than 8000 birds.
The kārearea is capable of flying at speeds over 100km/hour and catching prey larger than itself.
"Despite their fully protected status, New Zealand falcons are still shot by people, particularly when falcons occasionally kill racing pigeons or chickens. People should make sure they are aware of what animals they can hunt and learn to recognise them to avoid mistakenly hunting protected species," Connie says.
