    How you can use the data

    There are no restrictions on the audience. We’ve prepared the data to be used by the public, and as a tool by other organisations or agencies.

    The data is aggregated into tables, so you can view and compare results in different ways, eg number of claims per year by age, or by age group and location.

    The data can be used as a point of interest, a ‘did you know’, or as official ACC statistics feeding other organisations’ workstreams. 

    Differences between new claims and active claims

    When working with this data, you should be aware of the statistical differences between new claims and active claims.

    New claims

    New claims are based on the date the claim was lodged with ACC. The claim has one lodgement date, irrespective of outcomes, decisions, or severity, and is counted as ‘new’ once.

    Active claims

    Active claims are identified each time a claim has received a payment. For example, a payment to a client for weekly compensation or a health practitioner for a service provided to a client.

    Active claims are normally higher than new claims. This is because one claim may receive several payments over time, and could be active over several years.

    Request data

    If you can't find the data you are looking for, you can make an Official Information Request (OIA).

    Official Information Act requests

    If the requested data has identifiable information it will need an Ethics approval. Identifiable information is any piece of information that can be used to identify an individual directly or indirectly, eg case number, name, or address.
