The enthusiastic team of presenter Neil Oliver and six New Zealand experts in marine biology, history and social history explore the panoramic beauty of the coastline while investigating the formation and evolution of the nation: its history, its people and its culture.

The third series kicks off in Wellington, the world's southern-most capital city. Neil Oliver visits living Moriori artefacts and Michael Stevens hears about the day the natural wonders of the Bay of Plenty and reveal seaside stories from locations including the white-stone city of Oamaru and the Northland region of Kaipura. In a Coast New Zealand first, adventurer Dave Murray lands his plane on remote Big Bay in South Westland.
