What is Accident Compensation Corporation?

Legal Definition
The Accident Compensation Corporation (ACC) (Māori: Te Kaporeihana Āwhina Hunga Whara) is a New Zealand Crown entity responsible for administering the country's universal no-fault accidental injury scheme. The scheme provides financial compensation and support to citizens, residents, and temporary visitors who have suffered personal injuries.

The corporation was founded as the Accident Compensation Commission on 1 April 1974 as a result of the Accident Compensation Act 1972. Its principal governing act today is the Accident Compensation Act 2001. As a Crown entity, ACC is responsible to a Cabinet Minister via its Board of Directors. Unlike most other Crown entities, it has its own dedicated ministerial portfolio, which since December 2016 has been held by Michael Woodhouse.
