New Zealand Wars: A British victory against the Māori King Movement brought the Tauranga campaign to an end.

The New Zealand Wars took place from 1845 to 1872 between the New Zealand colonial government and allied Māori on one side, and Māori and Māori-allied settlers on the other. Though the wars were initially localised conflicts triggered by tensions over disputed land purchases, they escalated dramatically from 1860 as the government became convinced it was facing united Māori resistance to further land sales and a refusal to acknowledge Crown sovereignty. The colonial government summoned thousands of British troops to mount major campaigns to overpower the Kīngitanga movement and also conquest of farming and residential land for British settlers. Later campaigns were aimed at quashing the Pai Mārire religious and political movement, which was strongly opposed to the conquest of Māori land and eager to strengthen Māori identity. Māori religious movements that promoted pan-Māori identity played a major role in the Wars.

The Māori King movement, called the Kīngitanga in Māori, is a Māori movement that arose among some of the Māori iwi (tribes) of New Zealand in the central North Island in the 1850s, to establish a role similar in status to that of the monarchy of the United Kingdom as a way of halting the alienation of Māori land. The first Māori king, Pōtatau Te Wherowhero, was crowned in 1858. The monarchy is non-hereditary in principle, although every monarch since Pōtatau Te Wherowhero has been a child of the previous monarch. The eighth monarch is Nga wai hono i te po, who was elected and crowned in September 2024.

The Tauranga campaign was a six-month-long armed conflict in New Zealand's Bay of Plenty in early 1864, and part of the New Zealand Wars that were fought over issues of land ownership and sovereignty. The campaign was a sequel to the invasion of Waikato, which aimed to crush the Māori King (Kingitanga) Movement that was viewed by the colonial government as a challenge to the supremacy of the British monarchy.
