Several reports of one-legged weka have got the Department of Conservation concerned people are incorrectly laying possum traps that are injuring the birds.
A number of sightings have been reported to authorities; prompting DoC to issue a call for anyone who sees an illegal or incorrect trap to contact them immediately.
One-legged weka have been sighted in and around the Fiordland National Park - at the Chasm carpark on Milford Rd and Milford foreshore.
DoC's principal ranger for biodiversity, Lindsay Wilson, said the injuries were caused by the birds standing in incorrectly placed possum leg-hold traps.
"When working in an area with flightless birds, possum traps must be set at least 70cm above ground level on a surface that ground birds cannot gain access to.
