The first calves of the Hector's dolphins breeding season have been spotted in Akaroa Harbour.
Two baby calves have been seen swimming alongside their mothers near Akaroa Heads.
Black Cat Cruises chairman Paul Bingham said the calves are around the size of a rugby ball.
"It is really special to be able to see Hector's dolphins calving, that's literally the future of the species right there swimming around in the water so it's a beautiful sight."
