Methamphetamine is present in every region of New Zealand. Risk varies by intensity, not presence. Higher regional meth use increases the likelihood of contamination events within properties — but only property-specific testing can confirm contamination.

Any Level of Meth Residue Carries Cost

Any level of meth residue can contribute to overall contamination within a property. Over time, or when combined across surfaces, this can exceed regulatory thresholds — triggering remediation costs, insurance limitations, and ongoing liability for the property owner. There is no such thing as "no risk" contamination.

Understand your property's risk

Regional data is a signal. Only testing confirms contamination at your property.

Data reflects monitored wastewater catchments only and should not be extrapolated to represent entire districts. This map does not confirm contamination at any individual property — property-specific testing is required.
