What it contains

Your industry classification is based on your ‘predominant activity’. It is an important factor in the calculation of your premium. If it’s not immediately clear what your workplace’s predominant activity is, WorkSafe takes the following steps:

  1. Identify market revenue or non-market revenue.
  2. Identify and quantify intermediate inputs.
  3. Determine economic returns.
  4. Calculate total value added.
  5. Determine production function(s).
  6. Determine predominant activity.
