A group of scientists on an expedition to the Bounty Islands has been fitting satellite tags to penguins, and screening albatrosses and penguins for diseases.
The Bounty Islands lie about 670 kilometres south east of the South Island, and it's a two-day boat journey from Dunedin to get there.
The scientists have just left the Islands on their way back to Dunedin.
RNZ's Our Changing World host Claire Concannon spoke to Corin Dann.
