Methamphetamine testing


  1. Healthy Homes (NZ) Ltd uses two laboratories exclusively to carry out our laboratory analysis of samples taken. These labs are:
    • R J Hill Laboratories Limited: International Accreditation NZ (IANZ) NZS ISO/IEC 17025 – see with testing kits acquired from CHECK4METH.
    • Analytica Laboratories: International Accreditation NZ (IANZ) NZS ISO/IEC 17025; Analytica provides methamphetamine sampling kits which are consistent with NIOSH 9111, and is accredited by IANZ to undertake analysis of samples using a method that is consistent with NIOSH 9111.
  2. Healthy Homes (NZ) Ltd does not warrant the efficacy or accuracy of the Hill Laboratory testing systems, Analytica Laboratory testing systems and testing kits or the recommendations.
  3. If contamination is discovered then Healthy Homes (NZ) Ltd has a responsibility to notify an appropriate third party.
  4. Healthy Homes (NZ) Ltd cannot be held liable for contamination that was either not identified during our inspection, or for any contamination that has occurred after our screening process.

Limitations of Analysis Method

Detection limit is 0.02µg/sample for all analysis methods. This is cumulative if multiple samples are combined and tested together.

Limitations of Samples

There is no one test that can be performed that will guarantee any structure/property 100% free of methamphetamine. Decontamination is also designed to mitigate contamination to below the standard level, NOT to rid a property completely of all traces of methamphetamine.

Additionally, there is no one test that will determine the difference between manufacture or use. Levels will give an indication, but this is not definitive unless evidence is found in or around the property

Healthy Homes (NZ) Ltd carries out sampling using NIOSH 9111 compliant test kits and methods. For more info about our testing methods, please visit either see:

For more detailed information on the sampling methods used by Healthy Homes (NZ) Ltd see:



R J Hill Laboratory Limited

Hill Laboratories have the capability to test for traces of Methamphetamine from suspected contaminated dwellings. The test is carried out on wipe samples according to NIOSH method 9111, and has International Accreditation NZ (IANZ).

Swab samples from the dwelling are taken and sent to the laboratory where they are extracted and analysed using LCMSMS (Liquid Chromatography with Tandem Mass Spectrometry Detection).  Results for methamphetamine greater than 0.5µg/100cm² exceed the current New Zealand guideline levels.

Analytica Laboratory Limited

Analytica provides methamphetamine sampling kits which are consistent with NIOSH 9111, and is accredited by IANZ to undertake analysis of samples using a method that is consistent with NIOSH 9111.

NIOSH 9106 uses liquid-liquid extraction and gas chromatography/mass spectrometry (GC/MS) to measure multiple drugs. NIOSH 9109 uses solid-phase extraction and GC/MS to measure multiple drugs.

A non-intrusive moisture meter or infrared camera (when available or being ask to do so, at an extra cost to client) will be used around accessible joinery or identified risk areas, however these are an aid only and their results are not conclusive.
1.3 The pre-inspection report shall include grounds, retaining walls, house exterior, structure, foundations and sub floor area, roofs, ceiling space, security, plumbing outline (although recommended to seek a qualified tradesperson to inspect), electrical outline (although recommended to seek a qualified tradesperson to inspect), heating summary, interior summary of rooms, checking for operation of all doors windows and hardware, insulation, garage and carport buildings.

The report shall reflect conditions as found on the day of the inspection only and the procedure will be conducted in accordance with NZS 4306:2005 for the listed items.
1.4 We will consider Weathertightness, regardless of age, however it will not be measured against ‘Appendix A’ of the standards or to E2/AS1 of the Building Code, Matrix and Evaluation, as this would be a subject to a specialist report.

2. General: –
2.1 The acceptance of these “Terms & Conditions of Inspection Contracts,” by our clients is a requirement of our Insurers.
a. This is a report of a visual only, non-invasive inspection of the areas of the building, which were readily visible at the time of inspection. The inspection did not include any areas or components which were concealed or closed in behind finished surfaces (such as plumbing, drainage, heating, framing, ventilation, insulation or wiring) or which required the moving of anything which impeded access or limited visibility (such as floor coverings, furniture, appliances, personal property, vehicles, vegetation, debris or soil).
b. The inspection did not assess compliance with the NZ Building Code including the Code’s Weathertightness requirements, or structural aspects. On request, specialist inspections can be arranged of Weathertightness or structure or of any systems including electrical, plumbing, gas or heating.
c. As the purpose of the inspection was to assess the general condition of the building based on the limited visual inspection described in (a), this report may not identify all past, present defects or future defects. Descriptions in this report of systems or appliances relate to existence only and not adequacy or life expectancy. Any area or component of the building or any item or system not specifically identified in this report as having been inspected was excluded from the scope of the inspection”.
2.2 This inspection carried out at the client’s request is to provide the client with a better understanding of the property condition as observed at the point of time of the inspection and the company cannot be held accountable for what happens after this date.
2.3 It is not our policy to give verbal advice; we will provide a written report. If you do require the company to give verbal advice, we shall not be held responsible for that advice as the advice is the inspector’s opinion of the property’s condition at the time of the inspection.
2.4 The report is not to be used as a substitute for a final walk-through inspection.
2.5 The goal of the inspection is to identify any major visual deficiencies visible at the time of the inspection requiring immediate major repair.

It is possible for problems in a house to be disguised/camouflaged to prevent detection
3.2 While all care and effort is taken to discover and record irregularities and defects of the premise at the time of the inspection, it is important to note that the report is based on a visual above ground inspection only. Due to the size, complexity and hidden nature of construction, irregularities, defects may not always be viewed. The company will not move occupier owned items.
