Annual information received about employers and the self-employed can include multiple updates for a single employer.

The number of matched records in 2019/20 is higher than previous years due to extraction issues relating to IR and ACC’s transformation programmes. Initial incompatibilities and corrections led to repeat batches of data being processed.

ACC and IR are developing an AISA to replace this provision.

The utility of these provisions was assessed in the report MSD, MoE and ACC Matches (July 2014) and subsequently in Accident Compensation Corporation, Department of Internal Affairs, and Ministry of Business, Innovation and Employment (Motor Vehicle Traders Register) information matching (February 2020).
