There are different tests that can be done to check your property and determine any level of meth contamination. Selecting the right type of test is important to ensure you are in correct place in the contamination detection process. Read up below and use our Steps to help you determine what you need, or talk to us for advice on which test your property requires and why you need the correct type of test.
It is important to select the correct type of assessment that you require. This is determined by the purpose of the assessment. “What's your why?”
Engaging an assessment type that is incorrect can result in significant and unnecessary charges further down the track. There are requirements within the New Zealand Standard for Methamphetamine sampling for each assessment type. Properties cannot be cleared in accordance with the Standard until these criteria have been met.
Use this guide, from Step 1 to Step 5, to ensure you understand “why” you are testing and choose the correct assessment accordingly. Click on the steps below to learn more.

Assessment Type: Step 1 to Step 5
Step 1: Screening Assessment - Indicative An Indicative Screening Assessment is used to identify the presence or absence of methamphetamine contamination. “What’s your why?” for having an indicative test. Pre-Purchase or Pre/Post Tenancy? Health?
Step 2: Screening Assessment - Comprehensive This involves further investigation following a positive indicative screening assessment. Individual analysis of all or some of laboratory composite samples taken during step 1 will confirm rooms requiring decontamination. NB: only Detailed Site Assessments can clear rooms in accordance with the standard NZS8510:2017..
Step 3: Detailed Site Assessment This assessment, conducted by an IANZ Accredited sampling company, completes the requirements within NZS8510:2017 to determine and to exclude areas from the decontamination scope of works. The number of samples from each area is dependant on the building, surface materials and size of each airspace.
Step 4: Decontamination The areas confirmed in Step 3 as requiring decontamination, are now to be remediated. This is to be conducted by a professional decontamination company in order for a clearance certificate to be issued in accordance with the NZS8510:2017.
Step 5: Post Decontamination Assessment The Post decontamination assessment verifies a successful decontamination and ensures the property has met all the requirements of the standard including Step 3. A decontamination company must include a post decontamination report from an IANZ Accredited sampling company along with the clearance documentation.
