System description
Each week, Corrections extracts from its Integrated Offender Management System (IOMS) a file of all new prison admissions. Corrections ensure the fields contain valid data before electronically transferring it to ACC using a third-party electronic mailbox service. The file includes surname and given names, date of birth, gender, date received in prison and any aliases.
ACC compares the file with ACC records of people receiving earnings-related accident compensation. ACC then performs manual checks on each discrepancy before issuing a notice of adverse action (s.181 notice) copies of which are sent both to the last address on ACC's file, and to the prison.

During 2017/18 an upgrade to the IT systems delayed the processing of five weeks' data. A further five weeks of data was not processed because of lack of staff resources.
ACC note for 2019/20 that more clients are advising promptly of their change in circumstances and this has resulted in a fewer instances being identified by the match.
The utility of this provision was assessed in a report “MSD, MoE and ACC Matches (July 2014)” and again in “Accident Compensation Corporation, Department of Internal Affairs, and Ministry of Business, Innovation and Employment (Motor Vehicle Traders Register) information matching” (February 2020).
