We take domestic school leavers from Ministry of Education records and link them through to the Address Notification table, managed by StatsNZ, and Overseas Spells table managed by MBIE.
Each subsequent year we track the regional council each school leaver is reported spending the most time residing within.
To be considered overseas they must spend at least 6 months out of the country in that year.
