LEED annual technical notes – 2025 update – methods paper
1 December 2025
Technical notes about the annual statistics produced from the Linked Employer-Employee Data (LEED).
Background to LEED
Statistics from Linked Employer-Employee Data (LEED) annual tables provide information on New Zealanders’ interaction with the labour market and their sources of income. The longitudinal nature of the data allows analysis of income transitions, job tenure, multiple job holding, and self-employment. These statistics are analysed at a ‘person’ level and produced annually.
To produce person-level data, LEED is augmented with self-employment data. LEED is created by linking a longitudinal series of Inland Revenue’s Employer Monthly Schedule (EMS) and PAYE payroll data to employer data from Stats NZ’s Statistical Business Register (SBR). Official statistics produced from LEED every quarter measure labour market dynamics, providing an insight into the operation of New Zealand’s labour market at the job level. For more information see Guide to interpreting the LEED data.
