Donovan is an Air Quality Scientist with 16 years’ experience in New Zealand and Australia, specialising in air quality assessments. Donovan began his career as an ambient field technician primarily setting up, calibrating, servicing and troubleshooting faults at ambient monitoring stations for a wide range of airborne contaminants. The role also included reporting, QA/QC, and data validation of the results.
Donovan then moved into a consulting role in which he broadened his experience to include project management, emission inventories, air dispersion modelling using AERMOD, Calpuff, TAPM and Ausplume, environmental impact assessments, workplace exposure assessments, odour monitoring and modelling, and all facets of air quality assessments during contaminated site remediation.
After years of experience specialising in air quality assessments, Donovan now writes and presents expert evidence for both regional council hearings and environment court.
Most recently Donovan has developed an independent air quality consulting business, NZ Air Limited.
Donovan is able to develop practical solutions using a multidisciplinary approach embracing emission estimation, dispersion modelling and monitoring.

Air Quality Assessments and Air Quality Dispersion Modelling
Donovan has been instrumental in assisting a wide variety of industry in air quality assessments of environmental effects (AEE/EIS). His inputs include quantifying potential and actual effects and providing unique tailored mitigation measures to minimise impacts on the environment often creating win win scenarios for industry and regulators.
Donovan has also developed skills in air dispersion modelling (e.g. CALPUFF, TAPM, AERMOD and AUSPLUME) and applied these skills to air quality impact assessments for a broad range of clients. He has conducted modelling assessments to aid in the design phase of proposed infrastructure and for emission estimating from existing operations. His recent projects include:
