Indoor air quality (IAQ) is an important factor in maintaining healthy and productive workplaces across New Zealand. Many newer buildings are designed for energy efficiency, which can limit natural airflow and allow indoor pollutants to build up. When ventilation is inadequate, occupants may experience headaches, fatigue, respiratory irritation, reduced concentration or general discomfort. In New Zealand, IAQ concerns often relate to internal building materials, office activities, cleaning agents, moisture problems and the performance of heating, ventilation and air conditioning (HVAC) systems. Damp indoor conditions are a well-known contributor to air quality issues in many regions of the country.
Common contaminants found in New Zealand workplaces include:
These pollutants may cause short-term irritation or contribute to longer-term respiratory or allergenic effects. Symptoms often improve once a person leaves the building, which makes professional IAQ assessment essential for determining the underlying cause.
