Hawke's Bay Police are appealing for any information regarding the theft of little blue penguins in Napier.
Three penguins were taken from their nests in Perfume Point at Ahuriri around 10.30pm on January 24.
During the theft, one penguin was killed and its body dumped on the beach.
"Two groups of people were possibly involved in the thefts, including two older males and an older female, along with several teenagers," Sergeant Craig Vining said.
The woman was described as having a large build and long hair.
