Wellington Harbour is an arm of Cook Strait, covering some 76 km², with a two-km wide entrance at its southern end between Pencarrow Head and Palmer Head on the 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 k.p.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 ofLower 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. Another smaller but popular bay, for its beaches and Cafes is Oriental Bay. 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 small islands Matiu, Makaro and Mokopuna are located in the harbour. The entrance to the harbour can be quite dangerous, especially since Cook Strait to the south is notoriously rough. Close to the harbour's entrance lies Barrett Reef, its rocks breaking the water's surface at low tide. It was here in 1968 that the inter-island passenger ferryWahine grounded during a storm, with the loss of 51 lives.
Early history
Earlier names of Wellington Harbour
Wellington Harbour and its waterfront have gone by many names. The earliest known name for Wellington city, derived from Maori legend, is Te Upoko o te Ika a Maui or "the head of Maui's fish". Te Whanganui a Tara is another name Maori gave the area – a name said to come from Whatonga's son Tara, whom his father sent down from the Mahia Peninsula to explore southern lands for their people to settle. It literally means "the great harbour of Tara". Port Nicholson allegedly received its name from Captain James Herd, who sailed into the Harbour of Tara in 1826 and left it with its first European name, calling it after Sydney's Harbourmaster Captain John Nicholson. Colonel William Wakefield allegedly named Lambton Harbour in 1839 in honour of the Earl of Durham, who had the family name of "Lambton".
To increase the amount of usable flat land for Wellington city, the reclamation of Wellington Harbour started in the 1850s.
Transport
Wellington Harbour is a significant port serving the lower North Island, with the Regional Council-owned company Centreport recording around 14,000 commercial shipping movements each year. Wellington Harbour, the region's third largest container port, is located in Wellington City proper and there is a tanker terminal at Seaview, in Lower Hutt. Wellington harbour ferries first began operating at the end of the 19th century and regular crossings from central Wellington to Days Bay continue today. The harbour is also used by inter-island ferries, linking Wellington to Picton. A project to develop a walking and cycling route around the harbour, the Great Harbour Way, is gathering momentum.
