Te Tātua a Riukiuta

Te Tātua a Riukiuta was probably the most complex volcano in the Auckland volcanic field, consisting of five significant scoria cones and about a dozen smaller scoria mounds, sitting inside a large explosion crater. Along the edge of this crater to the south runs Mount Albert Road, and to the north, Landscape Road. At {{Convert|800|m|}} across and nearly {{Convert|200|m|}} deep, the explosion crater, which was caused by the initial eruption, was the largest in Auckland. The crater no longer exists today.{{cite book |last1=Hayward |first1=Bruce W. |last2=Murdoch |first2=Graeme |last3=Maitland |first3=Gordon |title=Volcanoes of Auckland: The Essential Guide |year=2011 |publisher=Auckland University Press|pages=141–145|isbn=978-1-86940-479-6 }}{{Cite web |title=Te Tātua a Riukiuta |url=https://www.maunga.nz/maunga/te-tatua-a-riukiuta/ |access-date=2022-07-19 |website=www.maunga.nz |language=en-GB}} The three largest scoria cones of the group were Big King at {{Convert|133|m||abbr=on}} high, East King at {{Convert|120|m||abbr=on}} high, and Highest King, which was {{Convert|135|m||abbr=on}} high.

Lava flows ran from here down a stream valley for three kilometres to Western Springs. These flows created lava tunnels which still exist under the surface. Thus, rainwater falling on Te Tātua a Riukiuta and the surrounding area is channeled underground for miles until it emerges at Western Springs Te Wai Ōrea Lake. Most of these lava tunnels have collapsed but sections of them form caves and can be accessed from private properties in the area. It was formerly believed that the lava had travelled further and formed Meola Reef at Point Chevalier, but in 2008 it was discovered that the Meola Reef lava had come from the older Te Kōpuke / Mount Saint John volcano.

The eruption occurred 28,500 years ago. Charred twigs and wood were found in six boreholes drilled through Te Tātua a Riukiuta lava flows in 2006 and carbon dating of the organic material produced six very similar dates around 28,500 years.{{cite journal |last1=Lindsay |first1=J.M. |last2=Leonard |first2=G.S. |last3=Smid |first3=E.R. |last4=Hayward |first4=B.W. |date=December 2011 |title=Age of the Auckland volcanic field: a review of existing data |journal=New Zealand Journal of Geology and Geophysics |volume=54 |issue=4 |pages=379–401 |doi=10.1080/00288306.2011.595805 |bibcode=2011NZJGG..54..379L |s2cid=129707270 }}

An earlier name for the volcano was Te Tatua o Mataaho (the war belt of Mataaho), which referred to a deity living in the Maungawhau crater.{{cite web|title=Story: Tāmaki tribes Page 1 – Tribal history and places|url=http://www.teara.govt.nz/en/tamaki-tribes/page-1|website=Te Ara|access-date=1 November 2014}} It was later adapted to Te Tātua a Riukiuta, which referred to Riukiuta, a senior priest of the Tainui waka who brought together diverse genealogical lines of the local tribes. The name Three Kings derives from the biblical Magi, and was named by Captain William Hobson's surveyor Felton Mathew in 1841. Big King refers to the second-highest (and only remaining) peak.

Te Tātua a Riukiuta was once the site of a pā, occupied during the Waiohua confederation era of the 17th and 18th centuries.{{cite book |title=Taua: 'musket wars', 'land wars' or tikanga?: warfare in Maori society in the early nineteenth century |last1=Ballara |first1=Angela |author-link1=Angela Ballara |year=2003 |publisher=Penguin |location=Auckland |isbn=9780143018896 |chapter=Tāmaki-makau-rau (Auckland isthmus) |pages=206}} The stone walled pā was built by Kowhatukiteuru, rangatira of the West Auckland iwi Te Kawerau ā Maki, to assist his Waiohua relative Te Rauiti.{{cite book| title=Local Area Plan: Te Henga (Bethells Beach) and the Waitākere River Valley.

The area has been drastically quarried over the years for the red scoria it contains, and only one of the three large peaks (Te Tātua a Riukiuta / Big King) remains today, largely because of the water reservoir that was built on its summit at the beginning of the 20th century. The reservoir is below the hydraulic grade of the area and is hence maintained as an emergency supply reservoir only.{{Citation needed|date=July 2022}}

However, the large scoria deposits in the surrounding area are still being quarried. The groundwater level became a problem for the quarry in 1995, and Winstone Aggregates, the company operating the quarry, arranged with the Auckland City Council to supply the water to the region. However, as a result of local opposition to this arrangement, the water is instead discarded into the sea. This dewatering has led to concerns about subsidence.{{Citation needed|date=July 2022}}

In the 2014 Treaty of Waitangi settlement between the Crown and the Ngā Mana Whenua o Tāmaki Makaurau collective of 13 Auckland iwi and hapū (also known as the Tāmaki Collective), ownership of the 14 Tūpuna Maunga of Tāmaki Makaurau / Auckland, was vested to the collective, including the volcano officially named Te Tātua a Riukiuta. The legislation specified that the land be held in trust "for the common benefit of Ngā Mana Whenua o Tāmaki Makaurau and the other people of Auckland". The Tūpuna Maunga o Tāmaki Makaurau Authority or Tūpuna Maunga Authority (TMA) is the co-governance organisation established to administer the 14 Tūpuna Maunga. Auckland Council manages the Tūpuna Maunga under the direction of the TMA.{{Cite web |title=Ngā Mana Whenua o Tāmaki Makaurau Collective Redress Act 2014 No 52 (as at 12 April 2022), Public Act – New Zealand Legislation |url=https://www.legislation.govt.nz/act/public/2014/0052/latest/whole.html |access-date=2022-07-17 |website=www.legislation.govt.nz}}{{cite news |last1=Dearnaley |first1=Mathew |date=27 September 2014 |title=Volcanic cones regain Maori names |work=The New Zealand Herald |url=http://www.nzherald.co.nz/nz/news/article.cfm?c_id=1&objectid=11332361 |accessdate=25 October 2014}}{{cite web |title=NZGB decisions - September 2014 |url=http://www.linz.govt.nz/nzgb-decisions-september-2014 |url-status=dead |website=Land Information New Zealand |accessdate=25 October 2014 |archiveurl=https://web.archive.org/web/20141029215200/http://www.linz.govt.nz/nzgb-decisions-september-2014 |archivedate=29 October 2014}}{{Cite web |last=Council |first=Auckland |title=Tūpuna Maunga significance and history |url=http://www.aucklandcouncil.govt.nz/about-auckland-council/how-auckland-council-works/kaupapa-maori/comanagement-authorities-boards/tupuna-maunga-tamaki-makaurau-authority/Pages/tupuna-maunga-significance-history.aspx |access-date=2022-07-17 |website=Auckland Council |language=en}}
