Our statutory obligations regarding meth contamination of properties
We have a number of statutory obligations to meet once we are made aware that a property has a certain level of methamphetamine contamination.
A report released in May 2018 by the Prime Minister's office found that there is unlikely to be a health risk to occupants of a property when the level of methamphetamine contamination is less than 15ug/100cm2, and there is no evidence that the property was used to manufacture methamphetamine.
In light of this report, we will:
- remove the methamphetamine contamination tag from the Land Information Memorandum (LIM) of an existing property if it is within the acceptable level (less than 15ug/100cm2), and there was no evidence of meth manufacture
- not take action on any new notifications of methamphetamine use (as opposed to manufacture) on a property when the level of contamination is within the acceptable level
- advise future property owners via the property's LIM if the testing of the property shows unacceptable levels of contamination (more than 15ug/100cm2)
- follow the existing processes as per the
NZ Standard for testing and decontamination of methamphetamine-contaminated properties if the level of methamphetamine contamination on a property is more than 15ug/100cm2, or when an illegal drug laboratory (a P lab) has been found on the property

How to arrange testing of your property
Testing of the property should be carried out by contractors who are:
- experienced to perform hazardous tasks.
To find meth testing contractors, check the Yellow Pages or search on the Internet.
The Ministry of Health (MoH) advises that professionals who assess and test a property must operate independently of commercial decontamination (remediation) companies.
What happens after the testing
Independent testing agencies can provide a report on the initial testing results. This report must be provided to us if we have been notified.
If initial testing confirms a property is contaminated with levels of methamphetamine above the acceptable level (15ug/100cm2), or if the notification was a result of methamphetamine manufacture, you will have to decontaminate it.
Vacate the property
We have a duty under the Health Act 1956 to ensure that the contaminated property is vacated while it is decontaminated.
If you have tenants you need to make sure they leave the property.
Decontaminate your property
If contamination levels are more than 15ug/100cm2, or if methamphetamine was manufactured on the property, we ask you to carry out remediation to decontaminate your property, as set out in the
NZ Standard for testing and decontamination of methamphetamine-contaminated properties
