Te Mamaku

Hēmi Tōpine Te Mamaku (died June 1887) was a Māori chief in the Ngāti Hāua-te-rangi iwi from the Whanganui region of New Zealand's North Island.

On 16 May 1846, Te Mamaku led a force of about 200 warriors in a devastating surprise dawn attack on British troops at Boulcott's Farm in the Hutt Valley.

[1] Returning to Wanganui (then known as Petre) in September 1846, Te Mamaku told the 200 European settlers that he had no quarrel with them and would protect them from attack by other Māori, but that he would not tolerate the presence of government troops.

A battle on 20 July resulted in about a dozen casualties on each side, after which the siege was lifted and Te Mamaku returned to his stronghold in the Pipiriki area, up the Whanganui River.

He opposed Te Kooti but was firm in his belief that the King Country was sacrosanct Māori territory, even to the extent of executing one Pākehā man who persisted in entering the area.
