Seatoun, an eastern suburb of Wellington, the capital city of New Zealand, lies on the east coast of the Miramar Peninsula, close to the entrance to Wellington Harbour (Port Nicholson), some seven kilometres southeast of the CBD. The suburb sits on an exposed promontory close to Barrett Reef, a dangerous area of rocky shallows upon which many ships have foundered, most notably the inter-island ferry TEV Wahine in 1968.
