Ngāti Whātua is a Māori iwi (tribe) of the lower Northland Peninsula of New Zealand's North Island. It comprises a confederation of four hapū (subtribes) interconnected both by ancestry and by association over time: Te Uri-o-Hau, Te Roroa, Te Taoū, and Ngāti Whātua-o-Ōrākei. The four hapū can act together or separately as independent tribes. Ngāti Whātua's territory or rohe is traditionally expressed as, "Tāmaki ki Maunganui i te Tai Hauauru" and "Tāmaki ki Manaia i te Rawhiti". The northern boundary is expressed as, "Manaia titiro ki Whatitiri, Whatitiri titiro ki Tutamoe, Tutamoe titiro ki Maunganui". The southern boundary is expressed as, "Te awa o Tāmaki". The area runs from Tāmaki River in the south to Maunganui Bluff (at the northern end of Aranga Beach on the west coast) in the north, and to Whangarei Harbour on the east coast. By the time of European settlement in New Zealand, Ngāti Whātua's territory was around the Kaipara Harbour and stretching south to , the site of present-day Auckland. History Ngāti Whātua descends from the ancestor Tuputupuwhenua (also known as Tumutumuwhenua). The iwi traces its arrival in New Zealand to the Māhuhu-ki-te-rangi canoe, which landed north of the Kaipara Harbour. They also descend from ancestors who migrated from Muriwhenua in the Far North and intermarried with the tribes in Ngāti Whātua's territory. By the 16th and 17th century, Ngāti Whātua had become established around the Kaipara Harbour. Rivalry with Ngāpuhi escalated in the early 19th century when Ngāpuhi acquired muskets. Ngāpuhi attacked Ngāti Whātua in 1807 or 1808 in the battle of Moremonui north of Dargaville - probably the occasion of the first use of firearms in Māori warfare. Ngāti Whātua overcame the Ngāpuhi warriors with hand weapons while Ngāpuhi were reloading their muskets, winning a decisive victory over the attackers. Ngāpuhi, led by Hongi Hika, exacted revenge in 1825 when they defeated Ngāti Whātua in the battle of Te Ika a Ranganui near Kaiwaka. On 20 March 1840 in the Manukau Harbour area where Ngāti Whātua farmed, paramount chief Apihai Te Kawau signed Te Tiriti o Waitangi, the Treaty of Waitangi. Ngāti Whātua sought British protection from Ngāpuhi as well as a reciprocal relationship with the Crown and the Church. Soon after signing the Treaty, Te Kawau offered land on the Waitematā Harbour to William Hobson, the new Governor of New Zealand, for his new capital. Hobson took up the offer and
