Apply for a reassessment or amendment

Anyone can apply for a reassessment of - or request an amendment to - the existing approval for a hazardous substance. We explain the process here.

A reassessment is a review of a hazardous substance that is already approved for use in New Zealand.

Amendments correct a minor or technical error in the existing approval of a substance, or involve minor changes to the approval.

There are set steps to follow for applying for reassessments or amendments.

How to apply for a reassessment Plus

A reassessment is a review of a hazardous substance that is already approved for use in New Zealand. This review could result in a decision to change the rules (‘controls’) for using the substance, or whether the substance should continue to be approved for use, or not.

There are two stages to complete to apply for the reassessment of the approval for a hazardous substance:

  • Step one: you must first make a formal application to show there are legal grounds to reassess the substance (grounds for reassessment). Your application will be decided by a sub-group of our HSNO committee.

  • Step two: you can apply for a reassessment if our committee decides that there are grounds for reassessment

Step one: show there are grounds for reassessment

Grounds could be established if you meet one or more of these criteria:

  • new information available about the substance’s effects
  • a significant change in the substance’s use or amount used
  • an alternative with more benefits and fewer risks is available
  • a consequence arising from the Health and Safety at Work Act.

To apply, complete the Grounds for Reassessment application form. Make sure you demonstrate at least one of the criteria for grounds for reassessment and include relevant supporting information. Any confidential or commercially-sensitive information should be included in an appendix and referenced from the application form (see ‘Supplying confidential information’ below). Send your application materials to: Reassessments@epa.govt.nz

Step two: apply for reassessment of an approval

If a grounds for reassessment is established for the substance, you may apply for a reassessment. There are two types of reassessment, ‘modified’ and ‘full’. A modified reassessment can only assess a specific aspect of the approval.

We will send you the Reassessment application form to complete once grounds are established. Any confidential or commercially-sensitive information should be included in an appendix and referenced from the application form (see ‘Supplying confidential information’ below). Send your application materials to: Reassessments@epa.govt.nz.

Once we have received your application, we will send you an acknowledgement by email with your assigned application number. We will then decide whether your application will proceed as a modified or full reassessment, and issue an invoice for the appropriate fee.

We may notify certain parties when we receive a reassessment application. These people will be given the opportunity to make a submission about the application. The general public will be notified when we receive an application for a full reassessment. For modified reassessments, we will decide whether public notification is needed, or not. If a modified reassessment is not publicly notified, we will consult with people who may be affected by the reassessment.

Request an amendment Plus

Amendments correct a minor or technical error in the existing approval of a substance, or involve minor changes to the approval.

If you want to apply for an amendment to a Group Standard, see our separate guidance 

To apply for a more extensive change, then you must apply for grounds for reassessment. Check our examples below to see if you should be applying for an amendment.

Amendments to correct minor or technical errors

An error is minor if it would not result in a different decision about the substance or affect the way the risk assessment was approached.

Examples of amendments to correct minor and technical errors include:

  • correcting typographical or drafting errors

  • adjusting existing controls to make them more practical, workable or enforceable

  • removing inconsistencies between the decision and the controls

  • correcting information that was inadvertently overlooked or misinterpreted at the time the decision was made – providing it does not lead to a change in the way the controls are applied.

Amendments that are minor in effect

"Minor in effect" means the amendment to the approval wouldn’t create any changes to the risk of using the chemical after applying the controls (the residual risk). This type of amendment would also not change the financial costs of complying with the approval.

Examples of amendments that are minor in effect include:

  • minor changes to controls that are considered reasonably insignificant or unnoticeable

  • changes to controls in response to new technology or new information becoming available

  • changes to approvals to provide consistency with other approvals.

How to request an amendment

To apply, complete the Amendment Request form and send it to us at: HSApplications@epa.govt.nz.

Any confidential or commercially-sensitive information should be included in an appendix and referenced from the application form (see ‘Supplying confidential information’ below).
