Cradock Channel
The Cradock Channel is one of three channels connecting the Hauraki Gulf with the Pacific Ocean to the northeast of Auckland, New Zealand. It is the central channel, lying between Great Barrier Island to the east and Little Barrier Island to the west. The other two channels are the Jellicoe Channel and the Colville Channel. Approximately 17,000 years ago during the Last Glacial Period when sea levels were significantly lower, the area was a part of a vast coastal plain. The area where the Cradock Channel exists was where the Waitematā Harbour (then a river) and the Mahurangi River passed before reaching the Pacific Ocean The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the contin ....

Little Barrier Island
Little Barrier Island, or Hauturu in Māori language (the official Māori title is ''Te Hauturu-o-Toi''), lies off the northeastern coast of New Zealand's North Island. Located to the north of Auckland, the island is separated from the mainland to the west by Jellicoe Channel, and from the larger Great Barrier Island to the east by Cradock Channel. The two aptly named islands shelter the Hauraki Gulf from many of the storms of the Pacific Ocean. Settled by the Māori between 1350 and 1650, the island was occupied by them until the New Zealand government declared the island a wildlife sanctuary in 1897. Since the island came under control of the government, it has been under limited access, with only a few rangers living on the island. In the Māori language, the name of the island name means "the resting place of lingering breezes". Along with its larger neighbour Great Barrier, it was given its English name by Captain James Cook in 1769. The island is a nature sanctuary whic ...

Waitematā Harbour
Waitematā Harbour is the main access by sea to Auckland, New Zealand. For this reason it is often referred to as Auckland Harbour, despite the fact that it is one of two harbours adjoining the city. The harbour forms the northern and eastern coasts of the Auckland isthmus and is crossed by the Auckland Harbour Bridge. It is matched on the southern side of the city by the shallower waters of the Manukau Harbour. With an area of , it connects the city's main port and the Auckland waterfront to the Hauraki Gulf and the Pacific Ocean. It is sheltered from Pacific storms by Auckland's North Shore, Rangitoto Island, and Waiheke Island. Etymology The oldest Māori name of the harbour was Te Whanga-nui o Toi (The Big Bay of Toi), named after Toi, an early Māori explorer. The name ''Waitematā'' means "Te Mata Waters", which according to some traditions refers to a mauri stone (a stone of Māori religious significance) called Te Mata, which was placed on Boat Rock (in the ha ...

Mahurangi River
The Mahurangi River in northern New Zealand flows through the town of Warkworth and into Mahurangi Harbour, which opens into the outer Hauraki Gulf. The Left Branch of the river rises in the Dome and flows through the Dome Valley, while the Right Branch rises on Moir Hill. The lower part is a tidal estuary that ranges in depth from below approximately at the channel entrance to approximately further upstream. The Mahurangi Harbour provides a sheltered anchorage for private pleasure craft in all weathers. History Approximately 17,000 years ago during the Last Glacial Period when sea levels were significantly lower, the Mahurangi River flowed into the vast coastal plain that existed where the modern Hauraki Gulf exists. The river met the Waitematā Harbour (then a river) east of Kawau Island, and flowed north-east between modern day Little Barrier Island and Great Barrier Island, eventually emptying into the Pacific Ocean north of Great Barrier Island. In colonial New Zealand ...

Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean
