Northland recorded the highest methamphetamine consumption per capita of any monitored district in New Zealand in Q2 2026, at 1,779 mg/day per 1,000 people — down from a four-quarter average of 1,909. Despite the decrease, Northland remains 47% above the national average of 1,214 mg/day and continues to lead the country. The property risk environment is shaped by significant social housing stock, rural communities with limited inspection infrastructure, and wastewater results that have consistently led the country.
Local Risk Advisory — Northland
Recommended: Enhanced Screening or Detailed Assessment. This region consistently records some of New Zealand's highest per-capita methamphetamine consumption. For any tenancy change or property purchase in Northland, a standard Baseline Screen may be insufficient. Consider an Enhanced Screening from the outset to gain individual sample-location results, or a full Detailed Assessment where formal documentation is required.

Other Regions
Data source: New Zealand Police / PHF Science – New Zealand Drugs in Wastewater Programme, Quarter Two: April–June 2026. Methamphetamine consumption reported as mg/day per 1,000 people for monitored wastewater catchments. Figures represent the sites tested and must not be extrapolated to nearby untested communities. Ratings are not official Police classifications.
This regional profile is an awareness resource only. Risk Intelligence Ratings are informed by wastewater monitoring trends, contamination pattern data, and field observations. They are not contamination claims about any individual property or person, and should not be relied upon as advice, evidence, or a professional assessment. Individual property conditions vary significantly regardless of regional profile.
From Regional Data to Property Assessment
Trace the path from national wastewater monitoring data to professional, property-specific meth testing. Regional data is an awareness signal — only testing confirms contamination at your property.
