Methodology
Average yearly income is calculated from new entrants in 2007 - 2011 for each year after entering the sector. Income is inflation adjusted using 2020.
New entrants are categorised into the following groups based on any education enrolments in the year leading up to starting work, or work experience in the past five years. They are categorised in a ranked hierarchy of:
- Secondary school leaver (enrolled within one year of starting work)
- Tertiary graduate (enrolled within one year of starting work)
- Career changer (at least one year of work experience within any other sector)
- Immigrant (first arrived in New Zealand within one year)
- Beneficiary (history of beneficiary income)
- Returning Kiwi (return date to New Zealand within one year)
- Others and unknowns
Such that a new entrant recently enrolled in tertiary education with more than one year of work experience is classified as a tertiary graduate as opposed to a career changer.
