Meth Inspection Cost NZ
What a meth inspection costs, what the inspection itself involves, and where the money actually goes — site visit, sampling, accredited laboratory analysis and the written report.
Inspection, laboratory analysis and report from $249 + GST
- NZS 8510:2017 sampling methodology
- IANZ-accredited laboratory analysis
- NZQA-qualified assessors (US 30892–30894)
A meth inspection is the on-site part of a meth test: an assessor attends the property, samples the surfaces that matter and sends those samples to an accredited laboratory. The inspection, the laboratory analysis and the written report come as one job, from $249 + GST at the baseline screening level. This page explains what that figure buys, because a cheap inspection that produces an unusable result is not cheap.
What a Meth Inspection Involves
1. Sample plan
The assessor plans which rooms and surfaces are sampled, against the methodology in NZS 8510:2017. High-touch surfaces, window sills, extractor fans, skirting and ceiling cavities are typical locations.
2. Surface wipe sampling
Each location is wiped with a laboratory-prepared swab over a defined area. Sampling technique matters: a sample collected badly cannot be rescued by the laboratory.
3. Chain of custody
Samples are labelled, sealed and recorded so the result can be traced back to the location it came from — the part that makes the report usable as evidence.
4. Laboratory analysis
An IANZ-accredited laboratory analyses the wipes, either as a composite or individually, depending on the testing level you booked.
5. Written report
Results are reported against the applicable threshold, location by location where the samples were analysed individually.
Meth inspection cost by testing level
All three levels are independent laboratory testing. The price differs because the amount of laboratory analysis differs, not because the visit does.
Baseline Screening Assessment
From $249 + GST
Composite laboratory analysis
- Assessor site visit and surface wipe sampling
- Samples combined into a single laboratory analysis
- Written report stating whether residue was detected
Initial checks and change-of-tenancy baselines
Enhanced Screening
Quoted on sample plan
Wider composite coverage
- More sample locations than a baseline
- More laboratory work, quoted before the visit
- Useful where risk indicators warrant wider coverage
Properties with prior results or elevated risk factors
Detailed Assessment
Quoted on sample locations
Each sample analysed individually
- Room-by-room, surface-by-surface results
- Evidence for insurance, Tribunal or a transaction
- The level used to scope decontamination
Claims, disputes and purchase negotiations
Quotes are exclusive of GST. Anything outside the standard sample plan is confirmed in writing before the visit.
A Routine Inspection Is Not a Meth Inspection
This is the most common misunderstanding in property management. A routine inspection is a visual condition check — tidy gardens, damaged fittings, smoke alarms. Methamphetamine residue is invisible. It leaves no smell, no stain and no visible trace, so no amount of looking finds it. Detecting it requires a surface wipe from a defined area and a laboratory analysis of that wipe, which is a separate service and a separate cost.
See property meth testing for when an inspection is worth booking, and portfolio support for programmes covering several properties.
Inspection Cost Against Remediation Cost
Decontaminating a meth-affected property in New Zealand typically costs between $15,000 and $30,000, and more where contamination is widespread. A baseline inspection from $249 + GST is therefore not the expensive part of the problem — it is the part that tells you whether there is a problem at all, before you commit to a tenancy, a settlement date or a renovation.
Getting a Firm Inspection Price
To price an inspection properly we need four things: the property address or suburb, the size of the property, what the inspection is for — a tenancy change, a purchase, an insurance matter — and any deadline you are working to. Send those through the contact form or call 0800 564 564, and the quote will state the testing level, the sample locations included and any access or travel charge.

As a landlord with multiple rentals across Hamilton, I needed someone independent — not a company that also does the cleanup. EnviroCheck's independence was the deciding factor. The risk calculator flagged issues I hadn't even considered.

We engaged EnviroCheck for a pre-purchase assessment on a property in Whangārei. The detailed assessment was thorough, the turnaround was fast, and it gave our buyer absolute confidence. I now refer all my conveyancing clients to them.
