This page tells you about the asbestos licensing system, including licences for asbestos removal and for licensed assessors.  

The Licensing section covers transitional arrangements for licensing, supervisor comptency tests, and includes an up-to-date list of all licensed removalists and assessors in New Zealand.

Asbestos removal licences

Class A 

Any type or quantity of asbestos or asbestos-containing material, including:

  • any amount of friable asbestos or ACM
  • any amount of asbestos-contaminated dust or debris (ACD)
  • any amount of non-friable asbestos or ACM.
 Class B
  • Any amount of non-friable asbestos or ACM.
  • ACD associated with removing any amount of non-friable asbestos or ACM.
No licence required

Up to and including 10m2 of non-friable asbestos or ACM, cumulatively, over the whole course of the removal project for the site.

ACD that is:

  • associated with removing 10m2 or less of non-friable asbestos or ACM
  • minor amounts of ACD, not associated with the removal of friable or non-friable asbestos.
NOTE: All removal work needs to be performed safely. Suitable controls need to be in place to ensure that the risks from asbestos have been minimised; including correct use of Personal Protective Equipment (PPE), Respiratory Protective Equipment (RPE), safe methods of work, decontamination facilities and the disposal of all asbestos waste in a licensed landfill.


Asbestos Assessor Licences

An asbestos assessor provides air quality monitoring during removal work, inspects the finished job and provides a clearance certificate.

Assessor licences are not required by law until April 2018. However, WorkSafe will accept applications for assessor licences from 4 April 2016 if individuals can provide evidence that they have the relevant qualifications and experience.



From 4 April 2018: 

  • air monitoring during Class A asbestos removal 
  • clearance inspections for Class A asbestos removal 
  • issuing of clearance certificates in relation to Class A asbestos removal work.

No licence is required before 4 April 2018 for the above work. Instead it can be done by a competent person*

No licence required, must be a competent person*
  • Clearance inspections for Class B asbestos removal (which may include surface testing and air monitoring)
  • Issuing of clearance certificates in relation to Class B asbestos removal.


* competent person means a person who has acquired, through training and experience, the knowledge and skills of relevant asbestos removal industry practice and who holds;

  1. a certificate for an asbestos assessor training course specified by WorkSafe, or
  2. a tertiary qualification in occupational health and safety, occupational hygiene, science, or environmental health.


WorkSafe has specified the following asbestos assessor training courses:

  1. Australian VET standard CPCCBC5014A Conduct asbestos assessment associated with removal
  2. British Occupational Hygiene Society proficiency module P404 Air Sampling of Asbestos and MMMF and Requirements for a Certificate of Reoccupation Following Clearance of Asbestos.
  3. W504 Asbestos and Other Fibres
  4. British Occupational Hygiene Society proficiency module IP404

New Zealand-based training courses are expected to be available later this year.

Note: If you have a current assessor licence from Australia, you can operate in New Zealand until 4 April 2018. Your Australian licence acts as proof that you meet the competent person requirement.
