Helping Protect Homes Before Contamination Happens
MethShield is a property warning and contamination risk management system developed by EnviroCheck — focused on prevention, not just detection.
A Proactive Prevention System
MethShield is a property warning and contamination risk management system developed by EnviroCheck. It is designed to help landlords, homeowners, property managers, and housing providers reduce the risk of meth contamination inside residential properties.
MethShield works by placing highly visible warning labels at key locations within a home where contamination risks may occur. These labels remind occupants that the property promotes meth-free living and has implemented contamination prevention measures.
Unlike traditional approaches that focus on testing after contamination has occurred, MethShield focuses on prevention.
A Simple Idea
Just as smoke alarms help protect homes from fire, MethShield helps property owners take proactive steps to reduce the risk of meth contamination.
MethShield does not guarantee a property will remain contamination-free. Instead, it provides a visible reminder that the property promotes safe, responsible use and contamination prevention practices.

Contamination Was Only Discovered After the Damage
After years of investigating contaminated homes throughout New Zealand, EnviroCheck identified a common problem: most contamination was only discovered after significant damage had already occurred.
By that stage, property owners often faced costly testing, remediation, insurance issues, tenancy disputes, and loss of property value. MethShield was developed to encourage early awareness and prevention before contamination becomes a problem.
What MethShield Aims to Do
Visible Deterrence
Highly visible warning labels at key locations remind occupants that the property promotes meth-free living.
Prevention-First Approach
Unlike testing after contamination occurs, MethShield focuses on reducing risk before it becomes a problem.
Responsible Tenancy
Encourages responsible occupancy behaviour and supports property management documentation.
Addiction Support Access
Provides access to addiction support information for occupants who may need help.
Where MethShield Labels Are Installed
MethShield labels are installed at key locations within the home — areas commonly associated with higher contamination risk during property investigations.
MethShield Works in Conjunction With Baseline Testing
MethShield is most effective when used alongside EnviroCheck's Baseline Screening Assessment. Together, they form a complete prevention and detection strategy for your property.
MethShield establishes visible deterrence and promotes meth-free living from the outset of a tenancy. Baseline testing then provides a documented, factual record of the property's condition — both before and after occupancy — giving property owners the evidence they need if contamination is ever suspected.

Why Use Both Together?
MethShield deters potential contamination from occurring during tenancy.
Baseline testing before a tenancy documents the starting condition of the property.
If contamination is suspected at any point, you have a factual baseline to compare against.
Together they support insurance eligibility, tenancy documentation, and due diligence obligations.
