“Explanation of key terms used in the Health and Safety at Work Act”

This section defines important terms used in the Health and Safety at Work Act 2015. Here’s a summary in simple language:

The Act explains what different words and phrases mean when used in the law. For example:

  • ‘ACC’ means the Accident Compensation Corporation.
  • ‘Health’ includes both physical and mental health.
  • A ‘hazard’ can be a person’s behaviour if it could cause harm, even if the behaviour is due to things like being tired or upset.
  • A ‘home’ is where someone lives and includes the garden and garage.
  • ‘New Zealand’ includes the land, surrounding waters, airspace, and the Ross Dependency in Antarctica.
  • A ‘workplace’ is defined in another part of the Act.
  • ‘WorkSafe’ is the government agency in charge of work health and safety.

The Act also explains who is considered a ‘worker’, what counts as ‘personal protective equipment’, and what ‘reasonably practicable’ means when talking about workplace safety.

These definitions help everyone understand exactly what the law means when it uses these terms. This is important so that workers, employers, and others know their rights and responsibilities under the Act.
