Includes the in-field sampling and assessment, laboratory analysis and a comprehensive report.


We recommend a detailed assessment if any of the following occur:

  • Your screening assessment was positive
  • There were reported detections of methamphetamine or pre-cursor chemicals
  • There were previous sampling discrepancies
  • The property was known or reported to contain manufacturing facilities.

Also known as a pre-remediation assessment, pre-decontamination investigation or detailed investigation, discrete sampling and the accompanying comprehensive report enables us to identify the magnitude and extent of the contamination. If decontamination is required, this investigation and report will assist contractors on exactly where to focus their decontamination efforts, therefore giving you a more accurate quote.

All our assessments and investigations comply with the New Zealand Guidelines for the Testing and decontamination of methamphetamine contaminated properties (NZS 8510:2017).

If there is evidence of soil contamination on the property, our experienced contaminated land consultants will undertake a Phase 2 Detailed Site Assessment as per the Ministry for the Environment Contaminated Land Management Guidelines Number 5 (2011).
