Muriwai, also called Muriwai Beach, is a coastal community on the west coast of the Auckland Region in the North Island of New Zealand. The black-sand surf beach and surrounding area is a popular recreational area for Aucklanders. The Muriwai Regional Park includes a nesting site for a large colony of gannets.

The New Zealand Ministry for Culture and Heritage gives a translation of "water's end" for Muriwai.

Geology

The Muriwai area was uplifted from the sea floor between 3 and 5 million years ago. Much of the landscape is formed by remnants of the eastern side of the Waitākere Volcano, notably the pillow lava formations seen along the cliffs south of Muriwai beach. The area is primarily formed by sand, sedimentary rock and piha conglomerate. Cliff walls dominate much of southern Muriwai. Muriwai Beach has black sand, caused by the iron content derived from the ancient volcanoes in the area, including the large Kaipara Volcano which was situated offshore from the Kaipara Heads, and erupted 23-16 million years ago. The black sand is moved up the west coast of the North Island by longshore drift.

Oaia Island is an island located off the coast of Muriwai.

Biodiversity

Motutara Island at Muriwai is a rare mainland colony for Australasian gannets. The rare korowai gecko is endemic to Muriwai area, primarily found in the sand dunes of Muriwai Beach.

History

The Muriwai area is traditionally a part of rohe of the Tāmaki Māori tribe Te Kawerau ā Maki, known originally by the name One Rangatira ("The Chiefly Beach"), referring to the tohunga Rakatāura's visit to the beach. The beach has spiritual significance to Te Kawerau ā Maki, as it is a part of Te Rerenga Wairua, the pathway that souls take to Cape Reinga to depart the world.

Te Kawerau ā Maki and Ngāti Whātua fought over the area when the latter settled south of the Kaipara Harbour. Muriwai became known as the border between Te Kawerau ā Maki and Ngāti Whātua, when peace was struct by the Te Kawerau ā Maki chief Te Hawiti / Te Au o Te Whenua. The area was settled by Ngāti Te Kahupara, a Ngāti Whātua hapū with Kawerau ancestry, until the 20th century.

The southern Muriwai Beach area was also known as Paenga Tohorā, referring to the many whale strandings that happened in the location. Te Au o Te Whenua lived at Te Korekore, a headland pā located at the south end of the beach. He was known for collecting and drying Paphies ventricosa (toheroa) collected from the Muriwai area, which he would trade with other Tāmaki Māori iwi and hapū for delicacies. The gannet colony headland was known as Ōtakamiro, the location of a pā named after the ancestor Takamiro. Other pā and villages to the south-east of the beach included Matuakore, Te Toheriri, Ngārihariha and Tirikohua. The modern name, Muriwai, means "End of the Water". It refers to the Te Muriwai, a kāinga located upstream of the beach along Ōkiritoto Stream, which over time became a name for the river valley, and eventually for the wider area.

During the late 19th century, John Foster established a flax mill at Muriwai, stopping in 1893 when this became less economically viable. In 1894 Muriwai Valley School was established. The school only operated part-time, due to the school's rural location. At the turn of the century, politician and Mayor of Auckland City Edwin Mitchelson constructed a wooden mansion at Muriwai which he named Oaia, referencing adjacent Oaia Island.

During World War II, the New Zealand Government feared that the Japanese army could invade Auckland along the west coast, landing at Muriwai. During this period, a United States Marine Corps camp was established at Muriwai, in part due to these fears.

In 1962, Muriwai became the location where the COMPAC submarine communications cable connected Auckland to Sydney, and a repeater station was installed 3 km from Muriwai Beach. This was used until 5 October 1983, when a cable fault at Sydney caused the system to cease working.

Location

One of several popular beaches in the area (others include Piha and Karekare), it experiences a population explosion in summer when Aucklanders head to the sea. It is in the Rodney Ward of the Auckland Region.

2013 shark attack

In February 2013, filmmaker Adam Strange was killed at Muriwai Beach while swimming about 200m offshore, when he was attacked by a small group of great white sharks. As a result, Muriwai Beach was closed for a number of days. Initial reports suggested the culprit was a bronze whaler, but it was later deemed more likely a great white was to blame. It was the first fatal shark attack in more than three decades in New Zealand.
