Wellington Harbour 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 western 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.
