The Pai Mārire movement was a syncretic Māori religion founded in Taranaki by the prophet Te Ua Haumēne. It flourished in the North Island from about 1863 to 1874. Pai Mārire incorporated biblical and Māori spiritual elements and promised its followers deliverance from 'pākehā' (British) domination. Although founded with peaceful motives—its name means "Good and Peaceful"—Pai Mārire became known for an extremist form of the religion known to the Europeans as "Hauhau". The rise and spread of the violent expression of Pai Mārire was largely a response to the New Zealand Government's military operations against North Island Māori, which were aimed at exerting European sovereignty and gaining more land for white settlement; historian B.J. Dalton claims that after 1865 Māori in arms were almost invariably termed Hauhau.

The Chatham Islands are an archipelago in the Pacific Ocean about 800 km (430 nmi) east of New Zealand's South Island. They are administered as part of New Zealand. The archipelago consists of about 10 islands within an approximate 60 km (30 nmi) radius, the largest of which are Chatham Island and Pitt Island (Rangiauria). They include New Zealand's easternmost point, the Forty-Fours. Some of the islands, formerly cleared for farming, are now preserved as nature reserves to conserve some of the unique flora and fauna.
