Ngati Mahuta an Iwi of Waikato Tainui.
Potatau Te Wherowhero, the first Maori King.
Potatau Te Wherowhero of Ngati Mahuta.
He was famous for being the first Maori king.
In 1860 the pan-tribal Kingitanga movement was formed and elected the first Maori king, Potatau Te Wherowhero; the tradition still continues today.
Tarapipi Te Waharoa (Wiremu Tamihana) of Ngati Haua of Tainui, became known as 'The Kingmaker' due to his invovement in the establishment of the Kingitanga Movement and the selection of Potatau Te Wherowhero as the first Maori King.
Wiremu Tāmihana took a leading role in the formation of the King movement and the election of Pōtatau Te Wherowhero as the first Māori King. Accordingly, he became known as 'Kingmaker'. When Te Wherowhero was confirmed as king in May 1859, Tāmihana placed a Bible over his head. But, It was Matene Te whiwhi and his cousin Tamihana Te Rauparaha from Ngati Toa who set out on a quest and looked around New Zealand for a worthy candidate for the Maori people.
As of 2016, Tuheitia Paki, GCCT, KCLJ, OStJ (crowned as Te Arikinui Kiingi Tuheitia), is the current Māori King in New Zealand. He is the eldest son of the previous Māori monarch, Dame Te Atairangikaahu, and was announced as her successor and crowned on the same day as her tangihanga took place, on 21 August 2006.
Like Australia, New Zealand is governed by a Prime Minister, but there is still a monarchal figure, currently Queen Elizabeth II. However, back in the 1850s, tribes of Maori from all over New Zealand came together to discuss appointing a king. The first king was Potatau Te Wherowhero, and the line has continued.

I'm assuming this is New Zealand Maori? There is no one single Maori chief. Maori in NZ are formed into different tribes and each tribe (iwi) and sub-tribe (hapu) of that tribe have their own chiefs. For example, Tumu Te Heu Heu is the paramount chief of the Ngati Tuwharetoa tribe/iwi (from the Taupo district) but because of the status of their family right throughout NZ history, he's often regarded as one of the most influential maori chiefs in New Zealand. There is however a Maori King/Queen in NZ. It is currently a King, King Tuheitia. The concept of Maori having a King or Queen is part of the Kingitanga Movement which was started by Waikato tribes during the 1850s in an attempt to unite all Maori tribes (who have traditionally competed against each other even when British arrived to colonise NZ) and slow down land loss/confiscation by the Government.
Apirana Ngata did not become the Maori king. He was a prominent Maori leader, politician, and advocate for Maori rights, but he did not hold the position of Maori king. The Maori king is a hereditary position within the Maori King Movement, established in the 19th century.
The current Maori King, King Tuheitia, has eight children.
Tuheitia Paki is the current (2011) Maori King, head of the Kingitanga or Maori King Movement.
