3 Types of Sensitivity
.5µg & 1.5µg / 100 cm2 = High Sensitivity 0 Tolerance test The most sensitive meth test kit available in the market. This can detect any small amount of Methamphetamine residue on any surface. Use for 1st initial screening. This is good if you suspect the homeowner is trying to cover up any Methamphetamine contamination in any house or car. Highly recommended if you do not want any trace of meth. (This is way below the recommended NZ 8510 Guideline & 2026 Guideline. If positive, it’s recommended to test with less sensitive 15 µg/100cm2 to measure the Meth residue.
15µg / 100 cm2 = 2026 Current Guideline
Next level test If (.5µg /100cm2) & (1.5µg/100cm2) sensitivity tested positive. This type of test is designed to assess where the contamination is within the property & process of elimination to identify which areas will require laboratory test to confirm the level of methamphetamine residue reading. You will save money not having to perform a laboratory test each area tested negative.
The Residential Tenancies (Managing Methamphetamine Contamination) Regulations 2026 came into force on April 16, 2026, setting strict legal thresholds for methamphetamine residue in New Zealand rental properties.
The new laws establish two primary residue limits (measured per 100 square centimeters):
- Contamination Threshold (15 µg): If any room or area tests above 15 µg/100cm², the property is legally considered contaminated and the affected area must be decontaminated.
- Uninhabitable Threshold (30 µg): If levels exceed 30 µg/100cm², the property is classified as legally uninhabitable. This triggers fast-track termination provisions—landlords can provide 7 days’ notice, and tenants can provide 2 days’ notice.
