Marine animal advocates are imploring people to take greater care when they see seals resting after an incident involving a man throwing stones at a seal's head.
Over winter months seals typically arrive along the Bay of Plenty's coastline to rest.
Department of Conservation volunteer Nathan Pettigrew said more seals were showing up in unusual spots around the Bay of Plenty, including port security booths, industrial areas and next to diners at a restaurant at Bridge Marina.
"There's been a seal at Pilot Bay, at Salisbury Wharf, over the past few weeks. He's been resting right up by the carpark, by the fence line. I could see him from my car when I saw a guy walk up to it. He stood right above it, looked around, picked up some stones from nearby and started throwing them at the seal's head.
