A juvenile fin whale stranded at Moncks Bay in Christchurch, New Zealand, has died, with recovery operations underway. Last Sunday, a pod of false killer whales and bottlenose dolphins were euthanised after becoming stranded twice on a reef near Māhia.

Coroner warning after heat-related death.

Otago University's Marine Science Professor Steve King said the summer stranding is nothing to be alarmed about. "It's a natural cycle of the pelagic food where climate change is happening but it is mostly manifested in the warm water conditions we are seeing right now."
