This report explores permanent and long-term external migration trends for Christchurch City since 1992. It highlights the countries where most of the City’s long-term and permanent migrants originate from, as well as where migrants are going when they leave Christchurch on a permanent or long-term basis. The report includes a breakdown of the occupation groups of migrants who are arriving and departing Christchurch, with an in-depth look at significant migrant groups and their ages and occupations. Refugees are another migration factor, and in this report the largest groups are identified by source country. Migration on a national scale is also examined, placing the Christchurch trends in a wider context. The report concludes with a summary of Trans-Tasman policy changes to migration and its effects on flows between New Zealand and Australia.
