New Zealand's Specialist Meth Testing Experts.
Envirocheck is a professional, independent meth testing company. We test properties, advise clients, and deliver clear results — with no conflicts, no agendas, and no guesswork.
Professional Testing. Independent Results.
Envirocheck's involvement in methamphetamine testing dates back to 2011, when Todd Sheppard approached and commissioned Hill Laboratories to undertake methamphetamine surface-residue testing for the emerging New Zealand property-testing market. That pioneering work laid the foundation for the independent testing and advisory practice Envirocheck operates today.
Our team brings deep technical expertise to every assessment. We follow NZS 8510:2017 precisely, use calibrated equipment, and deliver reports that are clear, defensible, and actionable.
Today we test and advise only — we do not remediate. That separation keeps our advice independent, so our findings are based purely on the evidence, nothing more.
Trusted by landlords, property managers, and housing providers across New Zealand, Envirocheck exists for one purpose: to give you the truth about your property. Our rental property meth testing services are built on this foundation.

Pioneering Baseline Meth Testing in New Zealand
EnviroCheck founder Todd Sheppard was an early pioneer of New Zealand's property methamphetamine-testing industry and developed the baseline meth testing approach — testing a property at the start of a tenancy or monitoring period and retaining that result as the property's documented starting condition. The timeline below documents that progression, with dated evidence records.
Commissioning Hill Laboratories
Todd Sheppard approaches and commissions Hill Laboratories to undertake methamphetamine surface-residue testing for the emerging New Zealand property-testing market — among the earliest independent surface-testing work in the country.
Developing the Baseline Approach
Working across residential tenancies, EnviroCheck develops the baseline meth testing approach — testing a property at the start of a tenancy or monitoring period and retaining that result as the property's documented starting condition.
Repeat Monitoring & Documentation
The baseline concept extends into repeat monitoring, giving landlords and property managers a documented point of comparison that end-of-tenancy testing alone cannot provide.
From Baseline to MethShield
EnviroCheck evolves the baseline concept into MethShield — combining baseline information with visible deterrence, property monitoring and risk-based follow-up.
Patent Application Lodged
MethShield's patent-pending technology is lodged with the New Zealand Intellectual Property Office (Patent Application No. 818430), including the concept of a controlled sampling/reference surface for repeat testing and historical contamination records.

That early baseline concept has continued to evolve. Today, EnviroCheck's MethShield system takes the approach further by combining baseline information with visible deterrence, property monitoring and risk-based follow-up. MethShield's patent-pending technology (NZ Patent Application No. 818430) includes the concept of a controlled sampling/reference surface that can support repeat testing and a historical contamination record.
What We Stand For
Independence
EnviroCheck tests and advises only — we do not remediate. With no remediation work, there is no financial incentive to find contamination, so our results serve you, not a cleanup invoice.
Transparency
Every report, every result, every recommendation is clear, evidence-based, and fully explained. No jargon, no confusion.
Accuracy
Our testing methodologies follow NZS 8510:2017 precisely. We invest in the best equipment and ongoing training for our team.
Education
We believe informed property owners make better decisions. That's why we invest heavily in training and knowledge-sharing.
We Detect to Protect™
Independent testing. Safer properties.
The Human Cost of Methamphetamine
At Envirocheck, we spend our days assessing properties. But behind many of those properties are people, families, and communities affected by methamphetamine.
Over the years, we have spoken with thousands of New Zealand families. Many describe living with constant uncertainty — hoping that a loved one will recover, hoping things will improve, and hoping to see the person they once knew return.
For many families, addiction can feel like a form of grief. The person is still physically present, yet their behaviour, priorities, and relationships may have changed dramatically. Parents, partners, children, grandparents, and friends often find themselves walking on eggshells, never quite knowing what tomorrow will bring.
We believe methamphetamine addiction is more than a property issue. It is a health issue, a family issue, and a community issue.
While our role is to provide independent property assessments and contamination advice, we recognise the wider human impact that addiction can have. Every contaminated property we encounter is a reminder that the consequences of methamphetamine extend far beyond walls and surfaces.
Recovery is possible. Support is available. Families are not alone.
If you or someone you care about is affected by methamphetamine use, we encourage you to seek support from qualified health professionals and addiction support services.
At Envirocheck, we see both sides of the issue. We see the impact methamphetamine can have on families and communities, and we also see the financial, emotional, and health consequences that contamination can have for property owners, tenants, and neighbours. We believe addressing the problem requires both compassion and accountability.
