Meth Contamination & What It Means for New Zealand Properties
Methamphetamine contamination is a significant issue in residential and rental properties across New Zealand. Even when there are no visible signs — no smell, stains, or obvious damage — residues from meth smoking or manufacturing can persist on walls, carpets, cabinets, and other surfaces. This can pose health risks, affect tenancy obligations, and impact property transactions.
Although MethTestingKit.co.nz does not provide full decontamination services, we equip homeowners, tenants, landlords, and property professionals with accurate DIY meth testing kits so that you can detect meth contamination early and act accordingly.
What Is Meth Decontamination?
Meth decontamination refers to the process of removing or remediating methamphetamine residue from an affected property. While this site focuses on testing and detection, understanding decontamination is essential because:
- Simply painting over contaminated surfaces will not remove residue permanently.
- Residue can bleed through paint layers over time if it’s not removed properly.
- Hazardous materials from contamination may require more than surface cleaning to eliminate.
If testing indicates contamination, property owners may need to seek professional remediation services — especially when required for insurance, tenancy regulations, or real estate sale conditions.
NZ Standards & Why They Matter
Meth contamination and testing in New Zealand commonly reference NZ Standard NZS 8510:2017 — Testing and Decontamination of Methamphetamine-Contaminated Properties.
This standard outlines:
- Surface sampling methods
- Acceptable residue thresholds
- The framework for testing and post-testing procedures
NZ Standards are important because they help property owners and professionals understand risk levels and compliance expectations.
While DIY kits do not replace laboratory or professional testing under NZS 8510, they are a highly practical first step to identify contamination and determine whether more in-depth testing is needed.
DIY Meth Test Kits: A Smart First Step
Immediate & Affordable Screening
At MethTestingKit.co.nz, we offer two main types of DIY testing:
✔ Instant Meth Test Kits
- Cost-effective solution for quick screening.
- Easy to use on interior surfaces.
- Uses German-developed technology with low risk of false positives/negatives compared to generic kits.
✔ Great for initial indication of contamination.
✔ DIY Laboratory Meth Test Kits
- Conducted by you, but samples are posted to an independent IANZ-accredited laboratory for analysis.
- Provides more accurate results because samples aren’t handled by third-parties before analysis.
✔ Better for decision-making compared to instant visual tests.
These kits empower you to:
- Test every room in your home or rental property.
- Understand whether there’s residue present above recognised thresholds.
- Decide if further professional inspection or remediation is needed.
How to Use Your DIY Meth Test Kit (Quick Guide)
- Identify Critical Areas — Start with high-use areas like bedrooms, living rooms, and kitchens.
- Follow the Instructions Carefully — Swab the surface area as directed.
- Interpret Results or Send to Laboratory — For instant kits, read results promptly; for laboratory kits, mail samples with pre-paid instructions.
- Determine Next Steps — If meth is detected, consider professional assessment or remediation options.
Remember: Instant kits are indicative, not definitive; they’re best suited to early detection, not legal or insurance purposes.
When Should You Test for Meth?
Testing is strongly recommended when:
✔ Buying a property (to avoid hidden contamination risks).
✔ Renting or re-letting a property (tenancy obligations and occupant safety).
✔ There’s any suspicion of meth use or production in the past.
✔ You’re concerned about your family’s health or investment value.
Testing early can save significant time, money, and stress later by identifying problems before they escalate.

Frequently Asked Questions
How accurate are meth test kits in NZ?
DIY kits are suitable for initial screening and indicative results, especially instant visual tests. Laboratory-analysed samples provide more accuracy than instant kits, but neither replaces full professional testing under NZS 8510:2017.
What levels are considered unsafe?
Under NZS 8510:2017, a surface above 1.5 μg/100 cm² may indicate contamination needing further investigation. Professional labs and standards bodies provide guidance on thresholds.
Is meth testing required before renting a property?
There is no mandatory legal requirement to test every rental, but tenancy and insurance obligations often make testing a wise and proactive choice.
How long does testing take?
Instant kits provide same-day results. Laboratory kits typically take a few days for analysis and reporting.
What if contamination is found?
If residue is detected with DIY tests, most property owners consult professional testers or remediation specialists who can perform testing compliant with NZS 8510, followed by remediation if required.
Can I rely on instant kits for legal or insurance purposes?
Instant kits are indicative only. For legal, insurance, or official compliance purposes, laboratory testing or professional sampling aligned with NZ Standards is recommended.

Meth Cover Up
We can help you how to find meth behind the paint.
Why Is painting over meth a problem?
Simply painting over a Meth Contaminated surface can result in the methamphetamine bleed through the paint layers over an extended period & may once again becomes available. The only way to deal with this is to remove the paint by stripping the painted surface. The waste is hazardous, dumping will be expensive, replacement cost for all removed surface for the entire dwelling including carpet, insulation, curtain, rangehood, extractor fans, light fittings & circuit breaker need to be dispose properly using a hazardous waste disposal.
