Winter may have the reputation as “mould season,” but in New Zealand, summer can be just as problematic. Warm temperatures, high humidity, and wet weather create ideal conditions for mould to grow quickly.
Mould is a natural part of our environment and usually harmless at low levels. However, when moisture is trapped indoors — from leaks, condensation, or hidden water damage — mould can become aggressive and reveal deeper issues within a building that might otherwise go unnoticed.
With New Zealand’s 2026 summer forecast to bring warmer-than-average, humid conditions under La Niña, mould spores can begin multiplying in as little as 24–48 hours. Certain species, such as Chaetomium, are particularly concerning. This mould flourishes in persistently damp materials, is difficult to remediate once established, and may signal past flooding, structural moisture problems, or design-related vulnerabilities. Left untreated, it can also present serious health concerns.
Early detection makes all the difference.
At Eurofins Environment Testing, we deliver independent, reliable mould testing and identification for both residential and commercial properties. Through air (spore trap) and surface (tape lift) sampling, we help identify issues early — before they escalate into costly or complex problems.
