Wellington Harbour ( , historically known as Port Nicholson) is a large natural harbour on the southern tip of New Zealand's North Island. New Zealand's capital city, Wellington, is located on parts of its western and southern sides. Lower Hutt is located on parts of its northern and eastern sides. The harbour, the sea area bounded by a line between Pencarrow Head to Petone foreshore, was officially named Port Nicholson until it assumed its current dual name in 1984. It is now a regional park, overseen by Wellington Regional Council. In the Māori language the harbour is known as Te Whanganui-a-Tara, "the great harbour of Tara". Another Māori name for Wellington, Pōneke, is said to be a transliteration of Port Nick (Port Nicholson). Geography Wellington Harbour is an arm of Cook Strait, covering some 76 km², with a two-kilometre wide entrance at its southern end between Pencarrow Head and Palmer Head on the southern tip of Miramar Peninsula. It has a maximum length of over 11 kilometres and a width of 9.25 kilometres. The harbour has an entrance over 1.6 kilometres wide from shore to shore and as it is surrounded by hills over 300 meters high, it provides sheltered anchorage in a region where wind velocities may exceed 160 km/h. The depth of water over the great bulk of the harbour exceeds 20 metres or 10 fathoms. The harbour is of seismic origin, and a major earthquake fault lies along its western shore. At the northern end of the harbour lies the narrow triangular plain of the Hutt River, which largely follows the line of the earthquake fault to the north-east. The city of Lower Hutt is located on this plain. The central city suburbs spread around the hills overlooking the west and south-west of Wellington Harbour and its two large bays, Lambton Harbour and Evans Bay. Lambton Harbour is surrounded by the reclaimed land of Wellington's central business district and contains the majority of the city's port facilities. Evans Bay is an inlet between Mt Victoria and the Miramar Peninsula that serves as a flight path to low-lying Wellington Airport. The small Oriental Bay features beaches and cafes. To the east of the harbour lie several small bays, most of which are populated by small coastal communities. The largest of these suburban settlements is Eastbourne, directly to the east of the northern tip of the Miramar Peninsula. The
