The Department of Conservation is urging people to take care around penguins after one was killed by a dog near the Whangawehi Stream on the Mahia Peninsula.
DoC East Coast operations manager John Lucas said little blue penguins were vulnerable as they left the nest and owners should keep their dogs under control around coastal areas.
"Little blue penguins are at risk of being attacked by dogs and to keep penguins safe, dogs should be on a lead at all times.
"Penguins have a strong smell which is quite attractive to dogs. While on land they are very vulnerable and have no defence against a dog's bite."
It is not the only little blue penguin to die in Hawke's Bay in recent weeks.
