The Department of Conservation in Otago is appalled by recent attacks on sealions and a penguin in the Catlins.
On Friday tourists on Surat Bay beach found a sealion with a spear embedded in its chest.
Another was found with large cuts on the beach between Kaka Point and the Nuggets.
The department's coastal Otago area manager, Robin Thomas, says that as well as breaking the law people who tease or attack sealions risk serious injury to themselves.
The department also says it's confident of catching the owners of two dogs that mauled a nesting yellow-eyed penguin to death at Jacks Bay on Saturday.
