ACC is a Crown entity, governed by a Board that is responsible to the Minister for ACC. The Chief Executive reports to the Board.
Minister for ACC
Our Minister is the Hon Judith Collins and our Associate Minister is the Hon Craig Foss.
Each year the Minister sends ACC a Letter of Agreement that sets out the various areas the Government would like us to focus on during the coming year, such as injury prevention in specific areas of concern.
The letter forms the basis of ACC's business planning process. This is formalised in the Service Agreement, which is negotiated between ACC and the Minister. The Service Agreement details what services the Minister expects us to deliver and how our performance will be measured. It also sets out what financial support the Government will supply to ACC.
Administrative support for the Minister’s ACC portfolio is provided by the Department of Labour.
