At Safe and Healthy Home Solutions, our work centres on protecting properties from methamphetamine contamination. But behind every contaminated rental, every failed test result, and every remediation project is a broader public health reality that property managers, landlords, real estate professionals, and social housing providers cannot afford to ignore.
New Zealand is losing three people a week to preventable overdose. That figure, drawn from an October 2026 NZ Drug Foundation report analysing coronial and Te Whatu Ora data, represents 169 accidental overdose deaths in 2025 alone. Across the past decade, 1,440 New Zealanders have died from entirely preventable overdose, accounting for 6,659 years of potential life lost in 2025 alone. Waatea News, reporting on the same findings, described the situation as a crisis deepening in real time, with stimulant harm surging alongside persistent ethnic inequalities.
These are not abstract numbers. They represent tenants, neighbours, whānau members, and community residents. They represent people who, in many cases, were living in ordinary rental properties.
Methamphetamine Consumption Is at Record Levels
The Drug Foundation report draws on wastewater data showing that methamphetamine consumption has been at record levels for the last two years. Hospitalisations from stimulants such as methamphetamine and cocaine have risen since 2023, while hospitalisations from other substances have remained stable or fallen. The report also notes that 16 of the 24 recorded overdose deaths involving cocaine occurred between 2023 and 2025, pointing to a concentrated and recent escalation in stimulant-related harm.
For those managing residential properties, this trend carries direct implications. Higher consumption rates mean a greater likelihood that properties are being used for methamphetamine smoking or manufacturing. Contamination does not always announce itself visibly. It accumulates quietly in wall cavities, carpet fibres, and ventilation systems, creating health risks for subsequent occupants who may have no knowledge of prior use.
The Harm Shows Up in Our Communities
Drug Foundation executive director Sarah Helm notes that stimulant deaths have been concerningly high since 2022, and that chronic long-term effects mean the harms appearing in current health data may only be the beginning. She has also called for better national monitoring of overdose deaths and hospitalisations, noting that the Foundation currently relies on gathering information from multiple sources, which creates challenges in identifying emerging trends quickly.
Overamping, which is a stimulant overdose caused by taking too much methamphetamine or cocaine, can be fatal without prompt medical attention. The volatility of the current drug market compounds this risk, with novel substances appearing in almost one in ten cases since 2016, often extremely potent and designed to mimic well-known illicit drugs. Among cases where complete information was available, two or more drugs were involved in 85 percent of overdose deaths.
Māori continue to bear a disproportionate burden, with more than twice the overdose death rate of non-Māori, and twice the overdose hospitalisation rate. People aged 45 to 54 have the highest overdose death rate of any age group.
What This Means for Property Risk
Property managers and landlords operate at the intersection of housing and public health. When a tenancy involves methamphetamine use, the risks extend in two directions: to the health of future occupants exposed to residual contamination, and to the wellbeing of the person using the substance.
Social housing providers, in particular, often house tenants with complex needs. Understanding the scale of stimulant harm in New Zealand helps contextualise why robust testing protocols, clear tenancy policies, and early intervention matter so much. A property that tests positive is not simply a remediation problem. It is a signal that someone in that home may be in serious difficulty.
Real estate professionals assessing properties for sale or rental also benefit from understanding this landscape. A record-level consumption environment means contamination risk is not confined to particular suburbs or property types. Diligent testing protects buyers, sellers, and future tenants alike.
Testing Remains the Foundation
None of this changes the practical steps available to property professionals. Regular methamphetamine testing, conducted by accredited professionals following NZS 8510:2017, remains the most reliable way to identify contamination and protect the people who live and work in your properties.
What the Drug Foundation’s data adds is context. The decisions property managers, landlords, real estate professionals, and social housing providers make about testing, remediation, and tenancy management sit within a public health environment where methamphetamine harm is measurable, significant, and growing.
Protecting your property and protecting people are not competing priorities. In most cases, they are the same priority.
