Methamphetamine, commonly referred to as ‘P’ in New Zealand, poses serious health risks when present in residential properties. This article explains how P contaminates a house, the risks involved, and what homeowners in New Zealand need to know about potential contamination.
How P Contaminates a House
When P is manufactured or smoked indoors, it releases a variety of chemicals that cling to walls, carpets, furniture, and even seep into the insulation and structural elements of a home. The process by which a house becomes contaminated depends on several factors, including the frequency of use or production and the ventilation within the property.
Meth contamination occurs primarily through airborne particles. As meth is smoked or produced, microscopic residues are expelled into the air. These residues contain methamphetamine along with other toxic chemicals, such as phosphine, ammonia, and hydrochloric acid. The particles gradually settle on surfaces throughout the home, creating layers of contamination that can be challenging to remove. In severe cases, the chemicals permeate beyond superficial areas, embedding into plasterboard, timber framing, and air conditioning systems, making decontamination difficult and costly.
Health Risks Associated with Meth Contamination
Meth residue is not just an issue of surface dirt—it is a serious health hazard. Prolonged exposure to meth contamination, even at low levels, can lead to respiratory issues, skin irritations, headaches, and nausea. Children and elderly individuals are particularly vulnerable, with symptoms including behavioural issues, developmental delays, and weakened immune systems due to their increased sensitivity to environmental toxins.
In high-contamination scenarios, residents may experience more severe health effects. Extended exposure to high levels of meth residue has been linked to respiratory diseases and other long-term health conditions. For those moving into a previously contaminated property, even after meth production has ceased, the invisible residue can linger, posing ongoing health risks for new occupants.

Testing and Legal Standards in New Zealand
In New Zealand, there are established guidelines for acceptable levels of meth contamination in residential properties. According to New Zealand standards, the meth residue level should be below 1.5 micrograms per 100 square centimetres in living areas where production has not occurred, although properties previously used for meth production often show much higher readings.
Property owners, especially landlords, are legally responsible for ensuring that homes are safe and compliant with health regulations. Pre-purchase meth testing has become increasingly popular as buyers look to avoid homes with hidden contamination. For rental properties, regular testing can protect both tenants and landlords by confirming that the home is safe for habitation and compliant with New Zealand guidelines.
The Decontamination Process
Professional decontamination is often required to safely and thoroughly remove meth residue from a property. Specialists use certified techniques and industrial-grade equipment to clean surfaces, remove contaminated materials, and ensure that the property meets legal safety standards. The decontamination process typically involves multiple stages, including testing, cleaning, retesting, and in severe cases, replacing affected structural materials.
