Independent Meth Test Report Reviews & Second Opinions
A meth test result is more than a number.
A laboratory result provides a measurement. Understanding what that measurement means requires experience, technical knowledge and an understanding of sampling procedures.
EnviroCheck Forensics reviews methamphetamine testing results for insurance companies nationwide, and provides independent second opinions for landlords, homeowners and buyers — helping interpret laboratory findings, assess sampling information and identify where further investigation may be warranted.
Whether you're an insurance company, property owner, landlord or buyer, we help turn complex technical findings into clear, evidence-based information.

Independent meth sampling, accredited laboratory analysis, property risk intelligence and MethShield® protection — we collect the samples, independent laboratories analyse them.
EnviroCheck provides professional technical reviews of methamphetamine testing reports and laboratory results for insurance companies throughout New Zealand, including reports presented as insurance-ready.
A review of an existing report is not an independent on-site investigation. Reviews are based on the information and evidence supplied, and we do not make insurance coverage or claim-settlement decisions.
Methamphetamine Laboratory Result Interpretation
Each review works through the report and the supporting information that came with it. Depending on what has been supplied, a review may consider:
Laboratory analytical results
How the reported figures were produced, what the analytical method detects, and what the numbers represent on the surfaces sampled.
Composite versus individual sampling
Whether a composite result or discrete individual samples were used, and what each approach can and cannot tell you about a property.
Sampling methodology and available documentation
How samples were collected, what documentation and chain-of-custody records accompany them, and where gaps in the record may sit.
Interpretation against applicable New Zealand standards and regulations
How findings read against NZS 8510:2017 and the current residential tenancies requirements, including the relevant threshold levels.
Contamination distribution and possible limitations of the testing
Where contamination was and was not detected, and the practical limits of the sampling pattern that was carried out.
Whether further assessment is warranted
Whether the evidence supplied supports additional investigation, a more detailed assessment, or no further action at this stage.
Scope of a review: reviews are based on the information and evidence supplied. A review of an existing report is not an independent on-site investigation. EnviroCheck does not make insurance coverage or claim-settlement decisions.

Already Have a Report? A Second Opinion Is Often the Cheapest Next Step
An independent meth report review is a technical reading of material you already hold — no site visit, no new sampling. We set out what the laboratory found, how the samples were taken, what the assessment level was, and which conclusions the results do and do not support. For landlords, homeowners and buyers, that is frequently more useful than commissioning another test to answer a question the first one never asked.
Landlords
You may be holding a report produced for a tenant, a contractor, or a previous manager, and need to know what it actually establishes before you rely on it in a tenancy matter or a re-letting decision. A meth test second opinion explains the result and the limits of the sampling behind it.
Homeowners
A report can arrive from an insurer's assessor, a buyer's inspector or a remediation contractor. An independent meth report review separates what the laboratory measured from what the report concludes, so you can see whether the recommendation actually follows from the data.
Buyers
A vendor-supplied report is not the same as a report you commissioned. Before you treat it as a clean bill of health, a second opinion checks the sampling plan, the assessment level and the methamphetamine laboratory result interpretation against what the property record shows.
What a second opinion covers
- Methamphetamine laboratory result interpretation — what each reported concentration means per surface, and how the composite or individual sampling approach affects that reading.
- Sampling and methodology review — sample locations, wipe technique, chain of custody and whether the plan was capable of answering the question asked of it.
- Assessment against the applicable standard — the threshold that applies to the property's situation, and whether the report states one at all.
Our nationwide review service for insurance companies remains in place alongside this. A review is an opinion on technical material; it does not decide cover, and we do not promise claim acceptance or any particular outcome. Submit a report for review or read understanding meth reports.

What to send with your report
Send what you have — a complete set is not a condition of review, but the more of the record we can see, the more of the result we can explain.
- The laboratory report or certificate of analysis, including the result table
- The sampling plan or field notes showing where each sample was taken
- Photographs of the sample locations, if the report includes them
- The assessment level stated (screening, composite, detailed or clearance) and the sampling date
- The decontamination or remediation report, where the review concerns post-clean verification
- Any correspondence from an insurer, tribunal or purchaser that the review needs to answer

Clear About What We Do
Accurate language matters in technical review work. Here is exactly where the boundaries sit.
What a result can and cannot establish
A laboratory result is a measurement of residue detected on the surfaces sampled. A result alone does not establish drug use history, identify any person, or prove the exact source of contamination.
A review is not an on-site investigation
A report review works from the documentation and evidence supplied to us. Where findings cannot be resolved from that material, the review will say so and identify what further investigation may be warranted.
Confidentiality
Reports submitted for review are stored privately and accessed only by our reviewers. We do not name insurance clients, display insurer logos, or publish confidential claims information without permission.
