Department of Conservation (DOC) staff are still trying to establish whether or not about 30 small green pellets left outside the West Coast conservancy office in Hokitika early yesterday are 1080 poison.
DOC publicity officer Ian Gill confirmed the pellets, which looked similar to the toxin, were found outside both entrances to the Sewell Street DOC headquarters.
The incident was reported to the police, and staff were awaiting test results, Mr Gill said.
