Tamatea / Dusky Sound is one of the largest and most magnificent fiords in New Zealand, a vast, glacially-carved landscape inundated by the sea. This remote and pristine marine environment, located in the southwest corner of the South Island, features a complex coastline with over 350 islands, creating countless sheltered coves, deep channels, and idyllic spots for mooring. The area is steeped in history, from early Māori exploration to Captain Cook's voyages, and has long been recognized as a haven for commercial and recreational fishing. Today, it represents one of the most ambitious marine and terrestrial restoration projects on the planet, aiming to become a fully intact ecosystem and a global "bio bank" for endangered native species.
