Scots made up nearly 20 percent of the immigrant population of New Zealand to 1920, yet until the past few years the exact origins of New Zealand's Scots migrants have remained blurred. From Alba to Aotearoa establishes for the first time key characteristics of the Scottish migrants arriving between 1840 and 1920, addressing five core questions: From where in Scotland did they come? Who came? When? In what numbers? and Where did they settle? In addition, this important study addresses, through statistical analysis, issues of internal migration within Scotland, individual and generational occupational mobility, migration among Shetland migrants, and return migration.
