Pre-Purchase Meth Testing

A pre-purchase meth test is the buyer's test. It is arranged by you, not the vendor, and it answers a question a building inspection does not: whether methamphetamine residue is present on the surfaces of the property you are about to own. Contamination is invisible, it is not picked up by a builder's report, and once settlement is complete it becomes your liability to identify, disclose and deal with. The window in which the result is useful is the window before your conditions fall due.

Why buyers commission their own test

• The property's history is often not knowable. Long tenancies, periods sitting empty and multiple owners all leave gaps that a LIM report does not fill.
• A vendor's assurance is not evidence. A clean-looking house, fresh paint or a recent renovation says nothing about what is on the surfaces or in the ceiling cavity.
• Leverage only exists before settlement. A result in hand during due diligence can support a price adjustment, a requirement that work be done, or a decision to withdraw. The same result after settlement is a cost you have already accepted.
• Insurers and lenders increasingly ask. A documented, independent test records the condition of the property on a known date, which is the kind of evidence a claim needs.

What the test covers

How each sample is taken and recorded is set out on our sampling technique page, and the rooms sampled in a typical house on the house meth testing page.

Screening or detailed assessment for a purchase?

A Baseline Screening Assessment from $249 + GST combines samples into one laboratory analysis. It is the least expensive way to learn whether residue above the reporting level is present across the property as a whole, and it suits a buyer who wants a first indication without committing to a full assessment.

A Detailed Assessment analyses each sample separately and reports room by room. That is the level appropriate when the result has to carry weight — a negotiation, an insurance notification, a tribunal or a decontamination scope — because it establishes where the contamination is and at what concentration. The difference between combined and individually analysed samples is explained in our composite meth testing guide.

Timing it around your conditions

Sampling takes roughly an hour for a standard house. Baseline screening results normally reach you within 24 to 48 hours of the visit, and detailed assessments take longer. Work backwards from the date your conditions are due and allow for access being arranged through the vendor or their agent — availability is not guaranteed, especially at short notice, so the earlier the booking the more room there is if a date has to move.

If you are buying at auction there are no conditions to work with at all, which changes the sequencing entirely. Our guide to meth testing before an auction covers how to plan around a sale date that cannot be extended.

Coverage

Pre-purchase testing is available across our serviced regions, with dedicated local information for the areas we work in most: Waikato, Hamilton, Auckland and Tauranga. Each page lists the towns and suburbs covered, so you can check your address before booking.

To arrange a pre-purchase test, send us the property address, the number of bedrooms and your condition date, or call 0800 564 564, and we will confirm the assessment level and the total price before booking.
