Introduction
This guide is as up-to-date and accurate as possible. The testing industry is changing and new
rules and new procedures will no doubt be developed over time. We will therefore update this
guide when needed, and indicate the date when it was changed. The Government has created
a potentially biased committee to review and set standards and resisted attempts to widen the
kinds of people who sit on this committee. We will be fascinated to see what they produce.
We have written this guide in an effort to bring light and clarity to a confusing subject, and to
counter the many myths and misconceptions that are being spread by some people inside and
outside the industry. We have used what we believe to be best practice and we have spoken
with many other people in the industry to collect their views as well. We have also attempted
to address the uncertainties still present in this industry.
Please let us know if you have any questions not answered in this guide and we will answer
them.

UPDATE:
The Ministry of Health and ESR have issued new guidelines for remediation, and we have
included their press release on page 15. This will no doubt be taken into account when the
Standards Committee release their draft recommendation in 2 weeks. This report does NOT
change how we test nor does it change the level we test to. It relates to remediation.

Executive Summary
There is no doubt that methamphetamine contamination is a problem for home owners in
New Zealand.
Houses in NZ are contaminated.
There are health implications for people who live and/or work in contaminated
spaces.
The risk is higher for landlords with rental properties being most vulnerable to both
meth smoker and manufacturers.
There is a difference between meth use and meth manufacture.
Meth use means the property is contaminated with methamphetamine.
Meth manufacture means many other toxic chemicals will also be present in the
property.
The level of meth is set at 0.5 micrograms per 100cm2 for clan lab remediation.
The Ministry of Health uses the levels of methamphetamine present as a proxy for the
other toxic chemicals.
There is no specific guideline for the residue left by the use of methamphetamine.
UPDATE: (However the ESR has just released their recommendations. See page 15.)
The industry is using the 0.5 micrograms per 100cm2
level as the point at which
remediation is required. This may change.
There are different methods for testing – we tell you the best.
We also address the major issues that conflicts of interest cause within the industry
and the wider real estate community.
The Government has set up a standards committee to look at these issues.
This is an evolving industry and we will keep you up-to-date.

What is ‘P’ (Methamphetamine)?
Methamphetamine, also known as chalk, ice, P, meth and crystal meth among many other
terms, takes the form of a white, odourless, bitter-tasting crystalline powder that easily
dissolves in water or alcohol.
It is a powerful, highly addictive stimulant that affects the central nervous system.
Methamphetamine was developed early in the 20th century from its parent drug,
amphetamine, and was used originally in nasal decongestants and bronchial inhalers. Like
amphetamine, methamphetamine causes increased activity and talkativeness, decreased
appetite, and a pleasurable sense of well-being or euphoria. However, methamphetamine
differs from amphetamine in that, at comparable doses, much greater amounts of the drug get
into the brain, making it a more potent stimulant. It also has longer-lasting and more harmful
effects on the central nervous system. These characteristics make it a drug with high potential
for widespread abuse.

How is ‘P’ manufactured?
Most of the methamphetamine abused in this country is manufactured in small clandestine
laboratories, with relatively inexpensive ingredients such as pseudoephedrine, a common
ingredient in cold medications. The availability of pseudoephedrine is now tightly controlled
in New Zealand, and customs are fighting a constant battle to stop it being illegally
imported.
Unfortunately, manufacturers are also increasingly using a different production process
(called P2P, from the precursor chemical phenyl-2-propanone) that does not require
pseudoephedrine.
Methamphetamine production also involves a number of other easily obtained chemicals that
are hazardous, refer to the list below.
Toxicity from these chemicals can remain in the environment around a methamphetamine
production lab long after the lab has been shut down, causing a wide range of damaging
effects to health. Because of these dangers, the Ministry of Health has provided guidance on
cleanup and remediation of methamphetamine labs.

List of chemicals commonly used:
Diluted HCl - also called Muriatic acid NaOH - also called lye
Ethyl Ether - aka Diethyl Ether - Et-0-Et
Ephedrine or pseudoephedrine
Distilled water
Iodine
Hydroiodic Acid
Red Phosphorus
Ammonia hydroxide
List of equipment used:
A glass eyedropper
Three small glass bottles with lids
A Pyrex dish
A glass quart jar
Sharp scissors
Clean rubber gloves

How is ‘P’ different from other drugs?
The methamphetamine molecule is structurally similar to amphetamine and to the
neurotransmitter dopamine, a brain chemical that plays an important role in the regulation of
reward, but it is quite different from cocaine. Although these stimulants have similar
behavioural and physiological effects, there are some major differences in the basic
mechanisms of how they work.
In contrast to cocaine, which is quickly removed from and almost completely metabolized in
the body, methamphetamine has a much longer duration of action, and a larger percentage of
the drug remains unchanged in the body. Methamphetamine therefore remains in the brain
longer, which ultimately leads to prolonged stimulant effects.
Although both methamphetamine and cocaine increase levels of dopamine, administration of
methamphetamine in animal studies leads to much higher levels of dopamine, because nerve
cells respond differently to the two drugs. Cocaine prolongs dopamine actions in the brain by
blocking the re-absorption (re-uptake) of the neurotransmitter by signalling nerve cells. At
low doses, methamphetamine also blocks the re-uptake of dopamine, but it also increases the
release of dopamine, leading to much higher concentrations in the synapse (the gap between
neurons), which can be toxic to nerve terminals.

What are the effects of ‘P’ contamination?
Methamphetamine use and manufacture can adversely affect people and animals for many
years to come who have the misfortune of being in a place where it was made or used.
Investigations have found meth contamination in motels rooms over three years after there
was known use or manufacture. Both smoking and manufacture destroy property and may
make people sick for years to come that inhabit, or use, the property. People who live in
houses where meth was smoked or manufactured may have enough in their systems to test
positive for it with a UA or hair testing. Furnishings and other possessions may become
contaminated to the point of needing to be discarded to protect inhabitant’s health. People
who smoke, or manufacture meth, may leave behind an invisible booby trap that can harm
anonymous people for years into the future.
Methamphetamine is a crystal that vaporizes when heated, as in smoking. The vapour clings
to surfaces and reforms into crystals. People who come in contact with these surfaces can
absorb meth through their skin or by touching contaminated surfaces then touching their
mouth, nose or eyes. Babies are especially vulnerable. They live in a world where they crawl
on all fours and everything is sampled by tasting. It takes only small amounts of meth to
affect a baby.
There seems to be little or no research on the affects of 2nd and 3rd hand meth on people or
pets, but it's safe to assume that small, chronic doses of the drug would cause the same
reactions as the users experience but on a smaller scale. Some symptoms of living with meth
contamination have been reported by people who believe they are living with meth pollution.
There are many possible sources of sick house syndrome where people and pets living or
working in a building are sickened as a result of contact with the building. Meth and mould
are the most commonly blamed sources for sick house syndrome, but there is no way to really
know without proper environmental and medical testing.
People who are exposed to meth pollution report speediness, loss of appetite, spaciness,
inability to concentrate, itchy skin, dry eyes, irritability, paranoia, colds, breathing difficulty,
sinus problems, headaches, nervousness, anxiety, acne and confusion. In more extreme cases;
convulsions and death of pets.
If your property has been used as a meth lab then the precursors can also cause major health
problems.
The ONLY way to know for certain if a property or vehicle is safe is to test it. If the
presumptive test is not negative for methamphetamine then the subsequent test should also
include a test for the precursors indicative of methamphetamine manufacture.

How widespread is ‘P’ contamination in NZ?
The short answer is we simply don’t know.
Some testers say they get a 60 percent failure rate... some say it is closer to five percent. Short
of testing every house in New Zealand, or a genuinely random sampling thereof, there is no
reliable way to tell.
To assess the level of contamination, we need an understanding of what kind of customer
base a tester has. For example if a tester is mainly testing properties they have reason to
believe may be contaminated, then the rate of failure will be much higher than a tester who
does mainly routine pre-purchase and between tenancy testing.
Different areas in New Zealand also have different rates of failure. However having said that,
no area and no class or quality of housing is fully exempt.
Rental properties appear to be at more risk that owner/occupied properties... but all houses
are at risk.
A Guide to the Methamphetamine Testing Industry Copyright John & Linda Reid, Drug Safe NZ Ltd. Website: DRUGSAFE.NZ
11 | P a g e
What is the safe limit for ‘P’?
There is no local or international standard for a safe level of methamphetamine
contamination. Various standards are applied in different areas around the world.
The Ministry of Health here in NZ have set a post-remediation limit of 0.5 micrograms per
100cm2 for properties used as methamphetamine laboratories. This has become the default
level that all properties are tested to, and any amount of methamphetamine over this limit is
regarded as a failed result.
The amount of methamphetamine present is taken as a proxy for the toxic chemicals used in
manufacture. There is certainly an argument that the level is too low for a property that has
been smoked in rather than cooked in. However the experts have not yet stated what a safe
level is, so most testers are using the 0.5micrograms/100cm2 level and testing to this
guideline.
A toxicologist was quoted on the TV show Fair Go as saying he would be happy for his
children to live in a property at a level of 12 micrograms per 100cm2.
It is also true that different people have different reactions to the presence of residual
methamphetamine. For example a level of 10-12 does not appear to affect Linda greatly for
the short time she is in a contaminated property, but a low level of 2-3 seems to affect John
greatly.
A child or a pet will be more susceptible than an adult.
We wish we could be more definitive, but we just cannot.
Perhaps these guys will get it right... See next page.
UPDATE:
The ESR are recommending (see page 15)
0.5 µg/100cm2 for houses where the drug has been manufactured (unchanged)
1.5 µg/100cm2 for houses where the drug has only been used – carpeted
2.0 µg/100cm2 for houses where the drug has only been used - uncarpeted.

Govt Appoint Committee
This has been taken from the Ministry of Business, Innovation and Employment and Bruce
Taylor is the Principal Advisor
Committee appointed to develop meth-testing
standard 02 JUNE 2016
A new committee is ready to go to develop a standard (NZS 8510) covering the testing and remediation
of properties contaminated by the manufacture or use of methamphetamine. The committee was
approved by the New Zealand Standards Approval Board on 4 May. Members of the committee and the
organisations they represent are as follows:
Name Organisation

13 | P a g e
The aim of the standard is to address a need for guidance on methodologies, procedures, and other
supporting material that will ensure a consistent and effective approach to managing the testing and
remediation of affected properties and treatment of their contents.
The committee will hold its first meeting at the end of June 2016. A draft of the standard will be prepared
and released for public comment later in 2016 for a period of 2 months. The final standard is expected to
be published between the end of January and June 2017, depending on factors such as the range and
complexity of comments received from public consultation.
Standard for testing and remediation of meth-
contaminated properties
29 MARCH 2016
Standards New Zealand is preparing to start work on developing a New Zealand standard on the testing
and remediation of properties used for the manufacture or use of methamphetamine.
In 2015 Standards New Zealand prepared a proposal for Local Government New Zealand and the
Ministry of Health to apply for funding under the Criminal Proceeds (Recovery) Act 2009 to develop a
standard on the testing and remediation of properties used for the manufacture or use of
methamphetamine. Funding of $60,497 was granted in December 2015.
The development of the standard is aimed at addressing a need for guidance on methodologies,
procedures, and other supporting material that will ensure a consistent and effective approach to
managing the testing and remediation of affected properties and treatment of their contents.
It is expected that the standard will include (but not limited to):
guidance on testing properties and contents for contamination
methods of assessing risks to health, safety, and the environment from meth-related chemicals
and contaminated material
best practice procedures for decontamination and remediation of properties and contents to
acceptable levels
methods of disposal of materials that cannot be decontaminated
information that supports auditing processes, which provide assurance that testing, risk
assessment, decontamination and remediation of properties, and disposal of contaminated
materials have been effective, and comply with legislative requirements.
Potential stakeholders with interests in proposed standard NZS 8510 include:
o meth testing and clean-up/remediation companies
o laboratories that analyse samples taken from meth-contaminated properties
o health, safety, and environmental regulators
o property owners, managers, and insurers.
Standards New Zealand contacted a wide range of stakeholders in January 2016 inviting them to
nominate representatives for consideration as members of the P 8510 committee.
A Guide to the Methamphetamine Testing Industry Copyright John & Linda Reid, Drug Safe NZ Ltd. Website: DRUGSAFE.NZ
14 | P a g e
The establishment of this committee is likely to be the first to be approved by the New Zealand
Standards Approval Board (the Board) that has been formed under the Standards and Accreditation Act
2015.
Under the Act, the NZ Standards Executive (NZSE) is responsible for establishing committees that will
develop new standards, such as NZS 8510, and to refer proposals for persons to be members or
chairperson of a standards committee to the Board for approval. In making its recommendations to the
Board, the NZSE will review all the nominations received. Once the Board has approved the
membership and chair of the P 8510 committee, the NZSE will advise the successful nominees, and the
work of the committee will begin.
The Board is due to have its first meeting in mid-April and we hope to be able to give an update on
progress of the development of the standard after that.

ESR Media Release:
Recommendations for methamphetamine contamination clean-up
26 October 2016
A Ministry of Health funded report provides key recommendations for the country's first
national standard for methamphetamine contamination.
The report, prepared by ESR, recommends that a different level be used to guide clean up
where meth has been used, compared to the level for houses where the drug has been
manufactured.
The report recommends that the current contamination level that prompts a clean-up stays the
same for houses where the drug has been manufactured but is four times higher for houses
where the drug has only been used and where there isn’t any carpet or the carpet is removed.
The level is three times higher for houses where only drug use is found, but where there is
still carpet in the house.
The report notes that drug residue on carpets is more likely to result in chronic exposure to
contamination for babies or toddlers who spend more time in contact with the floor.
The different levels reflect the level of health risk from living in a house where someone
smoked methamphetamine, and living in a house used to manufacture the drug.
Living in a methamphetamine laboratory environment means potential exposure to chemicals
at sufficient level to be linked to adverse cardiovascular, respiratory and dermal effects from
exposure to methamphetamine, organic solvents, acids, alkalis and other chemicals.
But people living in a house where previous occupants had only smoked methamphetamine
means potential exposure to low concentrations of the drug on surfaces with a much reduced
risk of toxicity.
The recommendations for houses with carpets in which there has only been drug use follow
those used in California, and which are increasingly being adopted by other US states.
Based on the recommendations now provided, the Ministry of Health believes houses which
don't trigger the clean-up levels for methamphetamine are as safe to occupy as any other
similar house.
The Ministry of Health believes the new recommendations will help guide clean-up efforts
based on an appropriate assessment of risk. The recommendations will now be considered by
the committee appointed by Standards NZ to develop the new standard.
In the absence of a guideline for remediating property contaminated by methamphetamine
use but not manufacture, these recommendations can be used in the interim. But the
recommendations will not pre-empt the standard which is currently being developed.
A Guide to the Methamphetamine Testing Industry Copyright John & Linda Reid, Drug Safe NZ Ltd. Website: DRUGSAFE.NZ
16 | P a g e
While the Ministry's recommendations are being considered by the Standards Committee, its
recommendations will be placed on the Ministry's website alongside its existing guidelines.
The new NZ Standard, once developed, will supersede the Ministry's existing Guidelines.
The Ministry of Health, which is also on the NZ Standards Committee considering the issue,
will be working with agencies involved to look at how promote information about the new
standard when it’s developed.
The recommended levels identified in the report are:
0.5 µg/100cm2 for houses where the drug has been manufactured (unchanged)
1.5 µg/100cm2 for houses where the drug has only been used – carpeted
2.0 µg/100cm2 for houses where the drug has only been used - uncarpeted.

Background:
Several agencies have roles related to the remediation of methamphetamine contaminated
buildings. The lead agency (regulator) for dealing with methamphetamine contaminated
buildings is the local council. Councils can take action using their powers under the Building
Act 2004 or the Health Act 1956.
These actions may include:
• recording the contamination on the property’s Project Information Memorandum (PIM) or
Land Information Memorandum (LIM)
• requiring the building owner to clean and/or close the building
• requiring the building owner to re-test the building
• requiring the building owner to demolish the building.
While not the regulator, the Ministry of Health developed guidelines for the remediation of
clandestine methamphetamine labs. These guidelines are now over six years old.
In 2015 Standards NZ (MBIE) began work to develop a new standard for dealing with
methamphetamine contaminated buildings.
In 2016, the Ministry of Health contracted ESR to undertake an independent review of the
current guidelines to provide updated advice on the values for remediating methamphetamine
contaminated buildings. The scope included seeking advice on both remediation of properties
used as clandestine labs and solely for recreational use.
The ESR report has now been received by the Ministry and the recommendations form the
advice the Ministry is presenting to Standards NZ Committee which is working on the
development of the new meth standards.
The analysis includes a review of evidence and comparison of the risk assessment approaches
used in New Zealand, Australia, Colorado and particularly California (which is based on a
comprehensive review of the toxicological literature, using human data, and noted as the
preferred comparison value for a safe daily exposure).

The ESR report also recommends an extra test for the presence of lead and mercury as part of
the clean-up of clandestine labs.

What does it mean if your property fails a test?
It means that your property has tested above the 0.5micrograms/100cm2 level in one or more
locations tested.
(UPDATE: If a property fails a screening test (level 1) then level 2 testing is required. This
will determine if the drug was manufactured or just smoked, and also the exact level of
contamination. It could well be that no remediation is needed up to 2.0 micro grams per
100cm2.)
Please read the next section about testing methods to assess the accuracy of the test used.
Assuming the test was accurate, and based on the current accepted guidelines, then people
living in the property should move out as soon as possible. Their clothes, furniture and other
chattels may need to be washed, decontaminated, or discarded.
(NOTE: buying second hand goods has become a riskier proposition as well!)
The house will need to be remediated and the level of remediation depends on the level of
methamphetamine and precursors present.
These levels of remediation range from a really good wash down of hard surfaces and
cleaning of carpet and curtains to stripping the plaster board, carpet, curtains, doors,
cupboards and appliances out of the house and replacing everything.
After remediation, the property needs to be tested again with a level 3 test before the house is
painted, has new plaster board put up and before new carpet, curtains and appliance are
replaced. Soil, water and air may need to be tested as well.
Unfortunately for landlords, it also means that if you cannot prove the tenant was the person
who contaminated the property, you will be liable to refunding rent and replacing damaged
property belonging to the tenant. The only way to protect yourself is to test between tenancies
so you can prove the property was not contaminated prior to the tenant moving in.

Types of testing and when to use them
There are many different tests and different ways of using these tests. What I outline here is
best practice for the most usual tests used in NZ and you should compare the methodology of
the tester you select with this list before employing them.
Level 1 - MMC Presumptive Forensic Narcotic Tests (Marketed in NZ as Check4Meth)
This is known as Level 1 Testing
MMC International BV is the manufacturer of presumptive narcotic tests for many
years. They have developed very specific narcotic tests in accordance with the
forensic standards.
The MMC Presumptive Forensic Narcotic Tests test for the presence of controlled
substances in powders, tablets, liquids, resins and on surfaces.
The Presumptive Forensic Narcotic Tests are very accurate and sensitive.
The tests only require nanograms of the substance for accurate testing.
First the site of the sampling is carefully selected by a trained technician, and the
template is applied to the surface. The swab is dipped into the buffer solution and
A Guide to the Methamphetamine Testing Industry Copyright John & Linda Reid, Drug Safe NZ Ltd. Website: DRUGSAFE.NZ
20 | P a g e
rubbed across the area outlined by the template. This transfers any methamphetamine
present on the surface to the swab. The swab is returned to the buffer solution and via
stirring and then agitation the sample is dissolved in the buffer solution.
Once the sample is obtained and dissolved in the buffer solution, the resulting liquid
is dripped into the tray of the cassette (a bit like a pregnancy test) and the result is
read within 1-5 minutes.
Advantages of the MMC Presumptive Forensic Narcotic Tests are:
Very sensitive
Able to detect the presence of drugs in a sample at levels of <1 ppm (part per
million)
Quick results (Visual in 1-2 minutes)
Specificity MMC FNT Tests Vs. GC-GC/MS: Negative: 99.38%, Positive:
97.45%
No hazardous chemicals
User friendly
Highly cost effective in comparison to laboratory screening
As reliable and accurate as laboratory screening
No cross contamination as each test is supplied with a separate dropper
of buffer solution
It is possible to test the remaining buffer solution to get an accurate amount of
methamphetamine and to confirm results.
Disadvantages of the MMC Presumptive Forensic Narcotic Tests are:
This is a pass or fail test at the 0.5micrograms per 100cm2 level. Therefore if
the test shows a fail, further testing is required.
A Guide to the Methamphetamine Testing Industry Copyright John & Linda Reid, Drug Safe NZ Ltd. Website: DRUGSAFE.NZ
21 | P a g e
Ideal for:
Pre-purchase screening
Routine testing between tenancies
Any occasion where there is not a high level of suspicion
In the control of a professional technician who knows how to use this test correctly
and is committed to getting an accurate result, this test is both very useful and cost
effective.
IN ALL CASES only one site can be tested with one swab and cassette.
Never allow any tester to use the swab without a template and/or in more than one
place in the property with the same swab.
A Guide to the Methamphetamine Testing Industry Copyright John & Linda Reid, Drug Safe NZ Ltd. Website: DRUGSAFE.NZ
22 | P a g e
Levels 2 and 3 - Laboratory Testing
This is known as Level 2 Testing
These are two examples of the kits used to obtain samples as supplied by IANZ
professional laboratories.
The kit contains:
Template
Swab in a test tube
Gloves
Rubber adhesive (similar to BluTak)
Contained in a separate plastic bag for each test kit
A properly trained technician will first select a suitable site to be tested.
The template will be applied to the wall. (See pic below)
A Guide to the Methamphetamine Testing Industry Copyright John & Linda Reid, Drug Safe NZ Ltd. Website: DRUGSAFE.NZ
23 | P a g e
Using a fresh pair of gloves (being careful not to cross-contaminate) the technician
will remove the swab from the test tube and use it to obtain a sample from within the
template area.
This swab will then be returned to the test tube, the details recorded on the outside of
the test tube and also on the order form and the tube is replaced in the plastic bag.
At least one site per room (including hallways and stairwells) will normally be tested.
A fresh testing kit, including the use of fresh gloves, is to be used for each site tested.
The test is designed to test for the amount of methamphetamine and precursors
present in an area of 100cm2 (as per the template). After the samples are sent to a
laboratory then the results will be available in 2-3 days.
Advantages of using Laboratory Testing:
Actual levels are given (if chemicals are present at a concentration of
0.02microgams/100cm2 or higher).
Gives levels of precursors as well as methamphetamine
Disadvantages of using Laboratory Testing:
It takes 2-3 working days for results to be known.
It costs much more than the MMC Presumptive test
Results under the ‘safe’ level of 0.5micrograms per 100cm2 can be a barrier to
buyers being confident about buying a property.
Ideal for:
Testing properties that have failed the MMC test
Testing properties that appear to be high risk
Post-remediation Testing
A Guide to the Methamphetamine Testing Industry Copyright John & Linda Reid, Drug Safe NZ Ltd. Website: DRUGSAFE.NZ
24 | P a g e
In the control of a professional technician who knows how to use this test
correctly and is committed to getting an accurate result, this test is very useful.
IN ALL CASES only one site can be tested with one swab (which is two pieces of
cloth in one test tube).
Never allow any technician to use the swab without a template and/or in more
than one place in the property.
(See an actual report on the next page showing methamphetamine and precursor
levels)
Alternative 1 - Laboratory Composite Testing
This is a less expensive option where the level 2 swabs are taken as above but,
when the laboratory technicians receive the test tubes, they combine a small
amount of each test into a single process. This gives you an overall indication if
there is methamphetamine present in the property or not. If meth is present, then
the technician can go back to the individual samples and test them separately to
determine the levels in all areas of the property.
Advantages of using Laboratory Composite Testing:
Actual levels are given (if chemicals are present at a concentration of
0.02microgams/100cm2 or higher).
Gives levels of precursors as well as methamphetamine
Disadvantages of using Laboratory Composite Testing:
It takes 2-3 working days for results to be known.
It costs more than the MMC Presumptive test
If the property fails then further testing of samples will be required and
this will cost the same as if the Level 2 testing had been done (in addition
to the cost of the laboratory composite testing).
Ideal for:
Testing properties that appear to be high risk

Not recommended - Field Composite Testing
This test involves using the Laboratory Test in a manner it was not designed to
be used.
One single swab is used in multiple areas of the property and then the single
test tube is sent to the laboratory for processing.
Advantages of Composite Testing
It’s cheap
Disadvantages of Composite Testing:
It takes 2-3 days to get a result
There is a certainty that there will be cross contamination if there is
any methamphetamine present in any of the sites sampled
It is almost impossible to read the results in a meaningful way unless
the result is negative
o If 5 sites were sampled, and the result was a level of 4.0
micrograms per 100cm2 x5 then you could be looking at 4.0
micrograms in one of those sites (and 0.0 in the rest), 2.0
micrograms in two sites and it has accumulated or 5.0 in one
site and then the result has ben diluted with the subsequent
swabbing being done.
Ideal for:
It’s just not ideal for any testing in our opinion.

Strip Testing
A strip test is done with a slim strip of paper similar to this:
I am not aware of anyone in NZ using this type of testing.

Random Sampling
All any tester can do is take random samples in a property. It is quite possible (and it has
happened) that two samples in the same room will return different results. There are some
rules that need to be followed in selecting sample sites, and that is where good training is
essential.
The technique used by the technician is also important to get accurate and consistent results.
Everyone associated with Drug Safe NZ is properly trained and supervised on the job before
being allowed to test properties alone.
Reporting Results
The report that is produced includes photographs of every site sampled, all the heat services
(cook top, wood stove) and also the wet areas.
A thorough inspection of the property inside and out is carried out to look for any physical
signs of methamphetamine use or manufacture. Photographs of the outside area are also
included in the report.
Every property that has passed our testing is issued with a Drug Safe Certificate like this:
Which is useful as a sales tool and also as a snapshot reminder of the day the property was
last tested.

Conflicts of Interest
One of the major concerns of home owners – and one that is brought to our attention
regularly – is the possibility of the tester having a conflict of interest.
Everyone at Drug Safe NZ has one objective only – to give the home owner, buyer or tenant
an accurate result.
In discussions with a representative of REINZ we talked about the wisdom of real estate
agents or their partners doing the testing and it was clear that this created a conflict of interest
and did not serve the client’s best interests.
And apart from a conflict of interest, there is the issue of confidentiality. Especially in small
towns, we all know how information can spread. One thing you can count on with Drug Safe
NZ is that we hold our clients’ results confidential.
Some building companies and some remediation companies also do testing – we see this as a
conflict of interest as well as they get to make money from the remediation of contaminated
properties.
So our recommendation is to only use an independent meth testing company for testing.
