title: History of New Zealand
context: The first full-blooded European infant in the territory, Thomas Holloway King, was born on 21 Feb 1815 at the Oihi Mission Station near Hohi Bay[19] in the Bay of Islands. Kerikeri, founded in 1822, and Bluff founded in 1823, both claim to be the oldest European settlements in New Zealand.[20] Many European settlers bought land from Māori, but misunderstanding and different concepts of land ownership led to conflict and bitterness.[18] In 1839, the New Zealand Company announced plans to buy large tracts of land and establish colonies in New Zealand.[21] This alarmed the missionaries, who called for British control of European settlers in New Zealand.
