The majority of the population of European lineage is of Scottish stock—the descendants of early Scottish settlers from the early 19th century. Other well-represented European groups include those of English, Irish, and Dutch descent. A large proportion of the Māori population are from the Ngāi Tahu iwi or tribe. Other significant ethnic minorities include Asians, Pacific Islanders, Africans, Latin Americans and Middle Easterners. Otago's early waves of settlement, especially during and immediately after the gold rush of the 1860s, included a substantial minority of southern (Guangdong) Chinese settlers, and a smaller but also prominent number of people from Lebanon. The region's Jewish population also experienced a small influx at this time. The early and middle years of the twentieth century saw smaller influxes of immigrants from several mainland European countries, most notably the Netherlands.
