The tender drops you at a narrow landing carved into the bay's eastern edge, where columnar basalt formations rise like organ pipes from the waterline. You navigate across rounded cobbles that shift and clack underfoot, the sound mixing with the bark of fur seals echoing off the amphitheatre of cliffs behind you. This is Pōhatu, a crescent of shore wedged between two headlands on Banks Peninsula's outer coast, accessible only by boat or a punishing overland trek that keeps visitor numbers mercifully low.

The bay's isolation has made it a stronghold for Australasia's smallest penguin species. As afternoon light slants across the water, you watch from the shoreline as blue penguins porpoise through the kelp beds, their slate-grey backs breaking the surface in rhythmic arcs. The conservation project here has tripled nesting numbers, and if you time your visit for dusk, you'll witness the evening parade as penguins waddle up established pathways to burrows hidden in the coastal vegetation.
The cliffs behind you tell the story of ancient eruptions—layers of rust-red scoria and black lava frozen mid-flow. At low tide, rock platforms reveal tidal pools where starfish cling to crevices and anemones pulse in the current. The water temperature hovers around thirteen degrees Celsius even in summer, a bracing reminder that you're standing on the edge of the South Pacific with nothing but open ocean between you and Antarctica.
