New Meth Regulations are now in effect

From today, New Zealand’s new methamphetamine regulations are officially in force, introducing clear, enforceable standards for how contamination is assessed and managed.

For property managers and landlords, this removes the uncertainty of previous guidelines and replaces it with a consistent national framework.

We’re already supporting clients across the country to adapt quickly and confidently.

The new regulations centre around two thresholds:

Above 15 µg/100 cm²: property is contaminated
Above 30 µg/100 cm²: property is considered uninhabitable

Above 15 µg, decontamination is required before the property can be re-let.
At levels above 30 µg, the property is considered uninhabitable. This may trigger termination rights under the Residential Tenancies Act, typically 2 days’ notice for tenants and 7 days for landlords, or agreement for temporary vacation during remediation.

The regulations introduce a standardised approach:

Testing must follow NZS 8510:2017 (Note – NZS8510 is currently being updated and an upadted version is expected to be published in early 2027)
Decontamination is required above 15 µg
Clearance testing must be completed by an independent provider, not the company that undertook decontamination
Final levels must be 15 µg or below

For property managers, this creates a clear, consistent, and Tribunal-defensible process.
For landlords, it reduces ambiguity and supports informed decision-making.

The expectations are now defined:

Properties above 15 µg cannot be rented or advertised
Relevant contamination must be disclosed where it impacts tenant health, safety, or habitability
Records must be retained for at least 12 months after the end of the tenancy

The regulations also introduce clear enforcement mechanisms. Non-compliance is treated as an unlawful act under the Residential Tenancies Act, with potential penalties applying to both landlords and tenants.

With clarity comes greater accountability, especially when managing properties on behalf of owners.

These regulations are a positive step forward, bringing clarity, consistency, and a clear path to compliance. But they also raise the bar.

The message is simple: understand the thresholds, follow the standard, and act early. Those who treat compliance as a discipline, not a checkbox, will be best positioned to manage risk and protect their portfolios.
