Tasman (Nelson / Marlborough) Methamphetamine Risk Profile

While below the national average, Tasman's upward trend and the region's mix of seasonal tourism, horticultural workforce accommodation, and permanent rentals create a property risk environment where documentation remains relevant.

The programme combines baseline methamphetamine testing, follow-up monitoring and visible MethShield signage to support ongoing property risk management.

A meth toxicology report — sometimes called a property toxicology report or methamphetamine laboratory report — is the documented laboratory result from a methamphetamine surface-residue test on a Tasman property.

EnviroCheck's reports are independent, NZS 8510:2017 aligned, and suitable for pre-purchase due diligence, tenancy disputes and insurance claims.

Landlords, property managers, and buyers across New Zealand rely on EnviroCheck for independent, evidence-based results.
EnviroCheck gave us a clear, defensible baseline before every new tenancy. Their reports are easy to read and their team genuinely understands the property management side. We've never had a Tenancy Tribunal issue since we started using them.

As a landlord with multiple rentals across Hamilton, I needed someone independent — not a company that also does the cleanup. EnviroCheck's independence was the deciding factor. The risk calculator flagged issues I hadn't even considered.

We engaged EnviroCheck for a pre-purchase assessment on a property in Whangārei. The detailed assessment was thorough, the turnaround was fast, and it gave our buyer absolute confidence. I now refer all my conveyancing clients to them.
