Joined by expert Ingrid Visser, Kina jumps into the warm waters off Northland to explore the mysterious underwater world of orcas.

Kina and the team head to the bottom of Stewart Island on an expedition ship to explore a mysterious population of sharks.

Kina reveals his secret great white shark spot - a seal colony located just off the rocks of Chatham Islands, where Kina himself was infact once bitten by a shark as a young man.

Along with a team of researchers, Kina is lucky enough to witness an unprecedented event at Port Pegasus - the birth of sea lion pups outside the Subantarctic Islands.
