Methamphetamine – What do landlords need to know?

One of the most topical issues facing New Zealand landlords is that of Methamphetamine, or ‘P’ as it is commonly known. It’s important for all investors to understand their responsibilities around this issue as well as the very real risks it can present for you, your tenants and your property.

Methamphetamine is an issue that isn’t going away anytime soon, with a Ministry of Health survey stating that at least 1% of the general population would class themselves as a ‘regular user’ – and this number is increasing.

Damage caused through the use and production of this drug can lead to serious health problems for those who inhabit contaminated properties as well as significant financial implications for owners of affected properties.

Insurance companies across NZ are reacting to the ever-increasing claim numbers and have implemented many changes in this space, including increased cost of premiums for landlords, higher excess amounts, and a lowering of claim caps to levels where in many instances your cover may not pay for all remediation costs.

What are the best practice steps for landlords?

Whilst there is no law stating that Methamphetamine testing is a requirement for landlords, we advise that pre-tenancy baseline testing is the most effective step to help protect yourself and your investment.

A baseline test is the only real way to pick up on any presence prior to a tenancy beginning and at the tenancy’s conclusion, a negative result will ensure you’re positioned correctly to help place liability and financial repercussions associated with contamination onto those who caused it.

Simply put, a lack of initial baseline testing makes it incredibly hard to prove the liability of tenants who may have caused contamination.

Prevention also stems from adequate tenant selection and thorough initial vetting of all applicants who apply to rent your investment property. The use of correct Tenancy Agreements that allow you to test for Methamphetamine during a tenancy (if required where correct notice is given) is also crucial, with many landlords not using the correct agreements that allow for this.

NZS 8510 Methamphetamine testing and decontamination standards

Standards New Zealand is a business unit within the Ministry of Business, Innovation and Employment that specialises in managing the development of industry standards. In June 2017, New Zealand Standard 8510 (NZS 8510) was officially released – placing structure and regulations around methamphetamine testing, clean up and decontamination.

These new standard, and rules, flow down through to the laboratories that analyse samples taken from methamphetamine contaminated properties; health, safety, and environmental regulators; property owners, property managers, councils, and insurers.

NZS 8510 has placed significant guidance on methodologies, procedures, and other supporting material to ensure a consistent approach to managing the testing and decontamination of affected properties.

For landlords and investors there are three key components (amongst others) in the standard that should bring significant peace of mind:

  1. Maximum allowable contamination levels of a property have been set at levels in line with worldwide

The maximum levels for a property to remain habitable without requiring further decontamination are:

  • 5 μg/100 cm2in any high use areas
  • 8 μg/100 cm2in any limited use areas

A ‘high use area’ is defined in the standard as an area in a property that can be easily accessed and is regularly used by adults and children. e.g. living areas, bedrooms etc.

A ‘limited use area’ is defined as an area that is likely to be accessed only by adults and for short periods of time. e.g. crawl spaces, wall cavities, under floor areas.

  1. The standard has confirmed that from now on there must also be a clear separation in duties between those who test for contamination at a property and those who are involved with its cleaning and Specifically, the standard states ‘Screening samplers shall be independent from decontamination contractors and avoid any other potential conflicts of interest.’This is a significant move towards providing transparency for consumers by removing any possible conflict of interest- which may have previously existed.
  1. The third key component the standards provide is around the need for testers and their companies to be properly accredited. This is a long awaited requirement to ensure the industry (and those who are making some serious decisions that can affect your investment) are all working to the same Specifically, NZS 8510 states:

‘Sampling and testing providers shall be accredited to NZS ISO/IEC 17025 or AS/NZS ISO/IEC 17020 as applicable with a scope of accreditation that includes the requested work’ and;

‘To provide confidence in inspection, sampling, and testing, on which a clearance certificate may be based, reports and certificates for inspection, sampling, and testing shall be endorsed by their accreditation body.’

The standard committee acknowledge that some provisions of the NZS 8510 standard, such as the accreditation requirements, will require some ‘lead-in time’ to implement. Nevertheless, these are all hugely positive steps in tightening up this industry and the way in which it conducts its business.

What are the different methods of testing for Methamphetamine?

There are varying methods of testing properties for methamphetamine contamination and they are definitely not created equal. Each method has it’s own place depending on the situation and cost etc, and it’s important that you understand the differences.

Landlord incurs unnecessary cost and time delay.

Remediation activities are delayed

If presence is detected, further analysis on individual samples can be easily undertaken.

Samples can be separated and analysed individually without anyone returning to site.Lower costs to undertake further analysis on samples.

Faster turn-around time to have clear view of problem and location(s) enabling quicker remediation.
