Occupational Hygienists in Canterbury, New Zealand

Professionals specialising in airborne contaminant monitoring and exposure assessment.

Occupational hygienists doing asbestos work in Canterbury operate under WorkSafe New Zealand's asbestos rules.

Air monitoring, clearance inspections and clearance certificates for Class A removal need a WorkSafe asbestos assessor licence, which is issued to individuals. Licensed assessors may also review a removalist's work plan before the job starts.

For Class B removal, an independent competent person can carry out the clearance inspection and issue the certificate.

Any building in Canterbury built or renovated before 2000 could contain asbestos. Importing asbestos-containing products into New Zealand has been illegal since 2016.

Ask whether a hygienist holds a current assessor licence if your job involves friable asbestos.

Frequently Asked Questions

When is air monitoring required during asbestos removal in New Zealand?

For Class A (friable) removal, an independent assessor must carry out air monitoring and issue clearance certificates under the Health and Safety at Work (Asbestos) Regulations 2016. Monitoring confirms airborne fibre levels are controlled before an area is reoccupied. WorkSafe NZ sets out when monitoring and clearance are required.

What qualifications should an occupational hygienist hold in New Zealand?

Look for membership of a recognised body such as the New Zealand Occupational Hygiene Society (NZOHS) and a laboratory accredited by IANZ for the analysis method used. On Class A work the assessor doing air monitoring and clearance must be independent of the removalist.

What does an occupational hygienist do in asbestos work?

Their main job is measuring airborne asbestos fibre levels to make sure workers and nearby occupants are not being exposed beyond safe limits. The workplace exposure standard in both Australia and New Zealand is 0.1 fibres per millilitre of air, averaged over eight hours. A hygienist will run air monitoring before, during, and after removal work, then issue a clearance certificate once the area is safe to reoccupy. They also review the removalist's control measures and advise on safe work procedures.

When is air monitoring required during asbestos removal?

It is mandatory for all friable (Class A) removal in Australia and for all licensed removal work in New Zealand. For non-friable (Class B) work in Australia, it is required when a risk assessment suggests fibre levels could exceed the exposure standard. You also need monitoring before an enclosure is pulled down and before a clearance certificate can be signed off. The person doing the monitoring must be competent in the methods, which usually means a qualified hygienist using NATA-accredited (Australia) or IANZ-accredited (New Zealand) procedures.

What qualifications should an occupational hygienist hold?

In Australia, look for membership of the Australian Institute of Occupational Hygienists (AIOH). Full members have a relevant degree and demonstrated competence. Many also hold Certified Occupational Hygienist (COH) status through the AIOH certification scheme. In New Zealand, the NZ Occupational Hygiene Society (NZOHS) keeps a similar register. For asbestos air monitoring specifically, the hygienist or their lab should hold NATA accreditation (Australia) or IANZ accreditation (New Zealand) for the fibre counting methods they use.
