Lodge gradual process disease or infection claim

Gradual process injuries occur over time and are caused by the gradual onset of a condition, a disease or an infection that is related to a work task, or the work environment. These may be covered by ACC. Work-related disease or infection, through a single exposure to the source of an infection, is not regarded as a gradual process injury.

Demonstrating cultural competency is important in the provision of services relating to all claims. Please refer to the ACC1625 Guidelines on Maori Cultural Competencies for Providers (PDF 2.0M).

What do gradual process injuries include?

To determine gradual process, disease or infection, ACC considers three key elements:

  • whether a particular property or characteristic of either the work environment or the client’s job has caused or contributed to the cause of the personal injury
  • whether the particular property or characteristic that has caused or contributed to the cause of the personal injury is present to any material extent in the client’s non-work activities or environment
  • whether the risk of suffering the personal injury is significantly greater for people who do the job or work in the employment environment than for people who do not.

How to lodge a gradual process claim

When lodging a claim for gradual process disease or infection, follow the general process for lodging claims and remember to tick the Gradual Process box when completing the ACC45 Injury Claim form.

What happens next?

Before ACC can make any cover decisions on these claims, we need to collect additional information from the client, their employer and their treatment provider.
