Raglan Harbor ( Māori : Whāingaroa ) is a natural harbor in the Waikato District of the Waikato regionon the North Island of New Zealand .
geography
The 33 km 2 natural harbor is located around 28 km west of Hamilton on the west coast of the Waikato District , with access to the Tasman Sea . The widely ramified body of water with numerous inlets has a north-south extension of around 8.5 km and, with a maximum length of around 13.5 km, extends around 12 km inland. At its widest point, the natural harbor measures around 3 km and is a modest 490 m in width compared to its extension at the port entrance. The coastline extends over a length of about 123 km. Of the 33 km 2 area of the port, around 24 km 2 are exposed to the tides . Water depths from 9 m can be found in the so-called channels , which reach down to a depth of 18 m. The mean water depth of the natural harbor is given as 2.5 m and the tidal range between 1.8 m and 2.8 m.
The natural harbor realizes the most important tributaries via the rivers Kerikeri River , Waingaro River , Waitetuna River and Opotoru River and together with the numerous creeks and streams (brooks) they drain an area of more than 165 km 2 . In the middle area of the upper part of Raglan Harbor , the approximately 3.5 km long Paritata Peninsula extends, dividing the port area into a South Upper Harbor and a larger North Upper Harbor .
The natural harbor can be reached via New Zealand State Highway 23 , which, coming from the east, passes south of the harbor area and ends in Raglan , which is located on the south side of the harbor, around 2.5 km from the harbor entrance.
geology
The Raglan Harbor is a sunken valley landscape, which was originally created by faults in the Miocene and was flooded by the sea after the last glacial period due to rising sea levels.
