The 2021 NZ Occupational Hygiene Society Conference, Change is in the Air, was a success with great attendance, and a day of interesting and thought-provoking sessions from experts across the field of occupational hygiene. Scheduled for the beginning of September, when New Zealand went into level 4 lockdown, it switched to a virtual conference. This was a new experience for everyone that was well received and made the day interactive. All the Air Matters team attended the conference, and special thanks goes to Mike, Amber and Rob, who put a lot of work into the NZOHS organising committee.
