New Zealand’s leading methamphetamine decontamination service. Fully certified, insurance-approved, and guaranteed to meet both the existing NZS8510:2017 standard and the new government thresholds effective 15 April 2026.
Our meth decontamination services cover every stage of the remediation process from initial testing through to your clearance certificate.
New Zealand’s approach to methamphetamine contamination has evolved significantly. For years, the industry operated under NZS8510:2017, which set the acceptable contamination level at 1.5 µg/100cm² in high-use areas. This standard was voluntary but widely adopted as best practice in tenancy disputes and legal proceedings.
From 15 April 2026, new government regulations are now legally in force, replacing the voluntary framework with clear, enforceable thresholds. Properties above 15 µg/100cm² are considered contaminated and must be decontaminated before re-letting. Properties above 30 µg/100cm² are considered uninhabitable and tenancy termination rights may apply.

Kiwi Safeas tests and cleans to both standards. Whether your insurer, property manager, or solicitor requires documentation under the old NZS8510:2017 threshold or the new 2026 government standard, we provide certified reporting that meets either requirement.
Is Your Property Contaminated?
Meth contamination can render a property unliveable, trigger insurance claims, and expose landlords to serious legal liability. The new 2026 regulations have increased both the obligations and consequences of non-compliance.
Standard Operating Procedure Under NZS8510:2017 (Pre-15 April 2026)
Prior to April 2026, Kiwi Safeas conducted all meth decontamination under NZS8510:2017, the national standard for testing and decontaminating methamphetamine-contaminated properties. This standard set acceptable contamination at 1.5 µg/100cm² in high-use areas. Although voluntary, NZS8510:2017 was accepted by courts, insurers, and tenancy tribunals as the definitive benchmark.
All historical clearance certificates issued by Kiwi Safeas reference this standard. If you require documentation for a property decontaminated prior to April 2026, we can provide the relevant compliance paperwork.
New Government Regulations (From 15 April 2026)
The new methamphetamine regulations introduce a standardised national framework. Key thresholds include: contamination above 15 µg/100cm² (decontamination required before re-letting) and uninhabitable above 30 µg/100cm² (tenancy termination rights apply). Final clearance levels must be at or below 15 µg/100cm².
Landlords must retain all records for at least 12 months after tenancy end. Properties above the threshold cannot be rented or advertised until cleared. Non-compliance is an unlawful act under the Residential Tenancies Act.
At Kiwi Safeas, we follow both the new 2026 regulations and previous guideline standards. We understand that some owners prefer a higher level of safety; therefore, we can carry out decontamination even if levels are below 15 µg/100cm² upon request. Whether you aim for the minimum legal requirement or a more comprehensive clean, we have you covered.
Note: NZS8510:2017 is currently under review. An updated version is expected to be published in early 2027.
Official government information
Certified meth decontamination to NZS8510:2017 and 2026 government standards. Insurance-approved. Results guaranteed.
Trust and Qulaity
From meth decontamination to flood, fire, mould, and crime scene cleanup. Kiwi Safeas handles every property hazard with certified expertise and consistent documentation across all of New Zealand.
Every technician holds current IICRC certification. Our firm certification is renewed annually — our qualifications are always current, not just claimed.
Every job starts with a thorough site assessment before any work begins. For meth jobs, independent laboratory testing is required. For all other services, we assess scope and confirm a fixed price. No guessing, no surprises.
We use industry-leading equipment — HEPA air scrubbers, thermal imaging, and moisture mapping — to achieve results standard cleaning cannot deliver.
We stand behind our work. If results don’t meet the required standard — whether that’s a meth clearance certificate, a mould-free inspection, or a flood restoration sign-off — we return at no additional cost.
Fixed-price quotes before work starts. No hidden fees. No surprise invoices. Our pricing is insurance-claim ready.
Contamination remediation is sensitive. All jobs can be carried out in unmarked vehicles on request, protecting your privacy and that of your tenants.
Our processes go beyond the minimum required by regulation. We take additional steps to protect occupants, neighbours, and the environment on every job.
Pre-assessment testing is carried out by an independent IANZ-accredited testing company (not Kiwi Safeas). This is required under the 2026 regulations to ensure fully unbiased results.
We can provide both option to the owner if they want to decontaminate all the areas above 1.5µg and whether they just want to remediate above 15µg areas.
Once the owner, insurer, or responsible party agrees on the price and scope, work starts within 2 working days of written confirmation. Decontamination takes 2–3 working days in summer and 3–4 working days in winter. Kiwi Safeas completely dries the property before post-decontamination testing.
The independent testing company carries out post-decontamination testing once Kiwi Safeas has completed and fully dried the property. Results must be at or below 15 µg/100cm².
Once you receive the post-decontamination testing report, send it to Kiwi Safeas. We issue the formal clearance certificate, the document required for your insurance claim, your records, and to legally re-let the property.
Full compliance documentation issued on pass. Your property is legally cleared and ready for tenancy or sale.

Common Questions
Everything you need to know about meth decontamination before making a decision.
Yes, in the vast majority of cases, meth contamination can be fully remediated. Our certified process involves professional testing, surface decontamination, air scrubbing, and final independent clearance testing.
Decontamination typically takes 2–3 working days in summer and 3–4 working days in winter. In winter, additional time is needed to completely dry the property before the independent testing company can carry out post-decontamination testing. Larger or more heavily contaminated properties may take longer. Your quote will include a clear timeline.
The old NZS8510:2017 standard (voluntary) set acceptable contamination at 1.5 µg/100cm². The new 2026 government regulations set enforceable thresholds: contaminated above 15 µg/100cm²; uninhabitable above 30 µg/100cm². All testing and decontamination must still follow NZS8510:2017 methodology. See: Link
Clearance testing must be completed by an independent IANZ-accredited laboratory (not the company that carried out the decontamination). This is required under the 2026 regulations.
If your property fails independent clearance testing after our decontamination, we return to re-treat at no additional cost. Our work is guaranteed to NZ standards.
