Did anti-1080 protesters shoot a weka?

Newshub reports:

An autopsy of the dead birds dumped at Parliament by 1080 protesters in September shows that one was shot, likely with a rifle.
The cause of death of the adult male weka is ruled to be “trauma consistent with ballistic injury”.
“Entry wound would indicate a ballistic calibre of .22 should be considered.”
Weka are a protected species. 
Under the Wildlife Act, it is a crime to shoot a protected species.
Forest and Bird is calling for the 1080 protesters who dumped the birds on the steps of Parliament to tell the truth about how the bird died.

So they claim to be against 1080 because it kills birds (in fact it saves millions of birds by killing their predators) and it turns out one of the birds they claimed was killed by 1080 was actually shot.
