Otago Harbour is the natural harbour of Dunedin, New Zealand, consisting of a long, much-indented stretch of generally navigable water separating Otago Peninsula from the mainland. They join at its southwest end, 21 km (13 mi) from the harbour mouth. It is home to the deep water port of Port Chalmers.[1]

The harbour was formed from the drowned remnants of a giant shield volcano, centred close to what is now the town of Port Chalmers. The remains of this violent origin can be seen in the basalt of the surrounding hills. The last eruptive phase ended some ten million years ago, leaving the prominent peak of Mount Cargill.

Substantial container port facilities exist at Port Chalmers, 9 km (6 mi) along the western shore from the harbour mouth. A channel along the western side of the harbour is regularly dredged, allowing vessels with a draught of 12.5 m to Port Chalmers, and 8 m all the way to the heart of Dunedin,[2] where New Zealand's frozen meat export trade began in 1882. The dredging of this channel, the Victoria Channel, was a major technological undertaking for the fledgling settlement of Dunedin in the mid 19th century. The eastern side of the harbour is shallow, with large sandbanks exposed at low tide.

Two islands form a line between Port Chalmers and Portobello in the lower harbour - Goat Island and Saint Martin Island/Quarantine Island. A smaller island known as Pudding Island lies close to the Peninsula shore and can be reached dry foot at low tide.

Portobello is home to one of New Zealand's leading marine research establishments, the Portobello Marine Laboratory, a department of the University of Otago. This lies at the harbour's edge on the tip of a small arm of the Otago Peninsula known as Portobello Peninsula.

Near the mouth of the harbour lies the partly-forested sandspit of Aramoana (Maori for "pathway to the sea"), infamous for a massacre of 13 people by a gunman, David Gray, in November 1990.

Adjacent to Aramoana stands the site that was proposed for New Zealand's second aluminium smelter. The proposal, in the late 1970s, was abandoned after major public protests. This area is an important habitat for many species of wading birds. Other wildlife to frequent the waters of the harbour include penguins, sea lions, and seals, and Taiaroa Head, at the tip of the Otago Peninsula, is home to a colony of Royal Albatrosses, the only such colony close to a major human urban area in the world.

The harbour is tidal, but as it is shallow it is seldom rough, and as such is popular for such water sports as yachting and windsurfing.

Due to shortage of land, a significant area at the head of the harbour has been reclamed since the founding of Dunedin, primarily for industrial use.[3] Smaller portions of land have also been reclamed at a number of places around the harbour, including Port Chalmers, Macandrew Bay, and Broad Bay.

The existence of the harbour was guessed by Captain Cook when he was off what is now the Dunedin Pacific coast in 1770. It is not known when the first Europeans entered but it was some time 'long before' 1810, according to the Creed manuscript discovered in 2003. George Bass made the Dunedin end of the harbour the north east limit of his proposed fishing monopoly in 1803. The American ship Favorite with its supercargo Daniel Whitney may have called in the summer of 1805 to 1806. Daniel Cooper, master of the London sealer Unity probably did call in the summer of 1808 to 1809 when his Chief Officer, Charles Hooper, probably gave his name to Hooper's Inlet on the Otago Peninsula. William Tucker (1784-1817) was with a gang dropped on islands off the Dunedin coast in November 1809 and with another man, Daniel Wilson, was at Otago Harbour on May 3rd 1810 when Robert Mason, master of the Sydney sealer Brothers anchored in the harbour and picked him up. This is the first, explicit and identifiable reference to a European ship in the Otago Harbour. The court record containing it made in 1810 refers to the harbour as 'Port Daniel', a name which stayed in use for some years.

Another English sealer, the Sydney Cove, Captain Charles McLaren, was anchored in the harbour late in 1810 when Te Wahia's theft of a knife, a red shirt and some other articles sparked what has been called 'The Sealers' War' - also - the 'War of the Shirt'.

A notable affray in that conflict occurred after James Kelly of Hobart anchored the Sophia in the harbour in December 1817 with William Tucker on board. After a visit to nearby Whareakeake (Murdering Beach) where Tucker and two other men were killed Kelly took revenge on Māori on his ship in the harbour, including a chief Korako. He then burnt a harbourside village,'the beautiful city of Otago', probably on Te Rauone Beach and certainly not at Whareakeake as has often been suggested.

A peace was concluded in 1823 and on July 17 of that year John Rodolphus Kent of the Naval cutter Mermaid from New South Wales, while in the Harbour, took 'the liberty of naming it (as it has not hitherto been named) "Port Oxley", in honour of the Surveyor General of the Colony'. As noted, it had already been named. In 1826 Thomas Shepherd, one of a party of intending colonists, explored the site of Dunedin and left the oldest surviving pictures of the harbour and nearby coast, now in the Mitchell Library Sydney.

From its origins as a secret sealers' haven Otago Harbour developed into a busy international whaling port after the Weller brothers established their whaling station at Te Umu Kuri, Wellers Rock, at what is now called Otakou in November 1831. The busiest whaling port south of the Bay of Islands, it was also the hub of the largest European population in New Zealand after the Bay of Islands/Hokianga district by the end of 1839. By that time whaling had collapsed and Dumont D'Urville and his officers, visiting in 1840, observed the port had become the centre of a riotous trade in liquor and prostitution. This continued until the Scottish settlers arrived in 1848 and made Port Chalmers and Dunedin the new centres on the harbour.
