This information explains what to expect when we investigate an injury caused by a workplace accident.

  • WorkSafe's role in investigating the accident
  • The decisions and legal processes that may follow
  • The services and support that are available to you during this difficult time


WorkSafe is the Government agency responsible for workplace health and safety in New Zealand. One of our tasks is to carry out fair and independent investigations into workplace accidents.

What will happen during the investigation?

WorkSafe inspectors and the New Zealand Police may both be involved in the early stages of the investigation. The Police investigate whether an offence has been committed under the laws the Police are responsible for, while we investigate whether any of New Zealand’s health and safety laws have been broken.

During the investigation we will try to find out:

  • what led to the accident
  • what, if anything, could have been done to prevent it
  • what, if anything, should be done to prevent an accident like this happening again
  • whether anyone involved in this accident broke the law, and whether any action should be taken against them.

As part of their role, our inspectors will (if possible) examine the scene of the accident, interview people who were involved, and review documents that relate to the accident.

How will WorkSafe let me know what's happening during the investigation?

Once we have begun investigating the accident, one of our inspectors will contact you to arrange a face-to-face meeting, or a conversation over the phone if this is not possible. If you have questions at any stage, or think you may have information that could help, please contact the WorkSafe inspector assigned to the investigation.

We aim to keep you informed about key stages of the investigation. There will be information that we are not able to share with you because it may affect possible legal proceedings.

We appreciate your patience and understanding as we work through the investigation process. Investigations are often complex and it can take months to reach a conclusion.

What will happen at the end of the investigation?

Criminal proceedings

After the investigation is complete, we will make a decision about whether to prosecute. Our purpose in prosecuting is to discourage others from breaking the laws we are responsible for enforcing, and to make the people who break those laws accountable.

If we decide to prosecute, the inspector investigating the accident (or another WorkSafe representative), will contact you to let you know, and explain that process.

For more information about how we decide whether to prosecute, see our Prosecution Policy.
