is the Māori name for a hill, 305 metres (1,001 ft) high, close to Porangahau, south of Waipukurau in southern Hawke's Bay, New Zealand.
The name on the sign that marks the hill is "Taumatawhakatangihangakoauauotamateaturipukakapikimaungahoronukupokaiwhenuakitanatahu", which translates roughly as "The summit where Tamatea, the man with the big knees, the climber of mountains, the land-swallower who travelled about, played his nose flute to his loved one". At 85 letters, it has been listed in the Guinness World Records as one of the longest place names in the world.
Tamatea-pōkai-whenua (Tamatea the explorer of the land) was the father of Kahungunu, ancestor of the Ngāti Kahungunu iwi. Mention of Tamatea's explorations of the land occur not only in Ngāti Kahungunu legends, but also in the traditions of iwi from Northland, where he is said to have explored the Hokianga and Kaipara harbours. In traditions from the Bay of Plenty region, he left a son, Ranginui, who is the ancestor of Ngāti Ranginui of Tauranga. Legends from the East Coast of the North Island tell of his explorations in Tūranga-nui (Gisborne), Māhia, Wairoa, Ahuriri (Napier), Heretaunga (near Hastings) and Pōrangahau. He travelled via the Mangakopikopiko River, over the Tītī-o-kura saddle via Pohokura to Lake Taupo. The Ōtamatea River and swamp is named after him. Tamatea is also the name of a place in Napier. Early South Island legends say that Tamatea sailed down the east coast. His canoe was wrecked in the far south, and transformed into Tākitimu mountain range. Tamatea then returned to the North Island, and travelled via the Whanganui River..
