Methodology
We take domestic school leavers from Ministry of Education records and link them to IRD taxation records, and businesses from taxation records subsequently to the Business Register.
Each year after leaving school we track whether school leavers are employed by a business with an ANZSIC06 code matching a construction industry.
We require individuals to be employed full time (a monthly income greater than the minimum wage * 40 hours * 4 weeks) for at least three months.
