Your obligations as an owner of a methamphetamine contaminated property

If we've received evidence that your property has been used to manufacture methamphetamine, we will instruct you to test the property and decontaminate it, if contamination levels are more than 15ug/100cm2.

How to arrange testing of your property

Testing of the property should be carried out by contractors who are:

  • qualified
  • equipped
  • 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.

If the contamination level is more than 15ug/100cm2

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.

The standard requires that you vacate and decontaminate the property. If you have tenants you need to make sure they leave the property.


You should know

If the property is occupied and hasn't been decontaminated within 20 working days we issue you with a Cleansing Order.

If the property is occupied and hasn't been decontaminated for a further 20 working days, we will issue you with a Closing Order. This requires the property to be immediately vacated.

If you don't comply with a Closing Order, legal proceedings will be carried out against you.

After the property is decontaminated

When your property has been decontaminated, you need to arrange a second test to ensure the property is no longer contaminated. 

You will need to send a copy of the test results to us.
