Visitors to Milford Sound have been treated to an increase in sightings of the rare Fiordland Crested Penguin over the past fortnight.
Southern Discoveries nature guide Dave Newman said the numbers of the penguins, known as tawaki, was encouraging.
"There's more penguins this year than we saw last year, which is really positive for the colony and great for our guests as there are only up to 3000 breeding pairs in existence," he said.
The penguins have been seen by tourists aboard the Encounter Nature Cruise as it comes close to the colony in Penguin Cove, where the penguins make their homes during the breeding season from July to November, and again between January and March to moult.
"We'll expect to see the penguins here until November when their chicks are ready to head out to sea," Mr Newman said.
