Practical guidance for New Zealand
Meth in rentals, property purchases and workplaces
Responsibilities, disclosure, insurance and records depend on how the property is used.
Guidance reviewed 7 October 2026. This is general property information; health, legal and insurance decisions depend on the circumstances.
Who pays, and can a tenancy end because of contamination?
A landlord’s duty to address a contaminated rental is separate from proving a claim against a tenant. Evidence needs to establish the circumstances and responsibility; a later positive test alone does not identify the person or timing. Before a new tenancy, address the relevant findings rather than passing the unresolved problem to the incoming tenant.
Termination for residue above 30 µg/100 cm² has conditions under the 2026 rules; it is not automatic eviction for any positive test or a result exactly at 30. Rent, relocation, notices and disputes need case-specific advice. The usual careless-damage limit should not simply be applied to intentional or unlawful contamination, and an insurance excess is not automatically owed by a tenant. Keep evidence and consult Tenancy Services or a legal adviser before recovering costs, deducting bond or ending the tenancy.

Will insurance pay, and can a landlord claim GST?
Meth cover varies by policy, cause, exclusions, testing history, reporting requirements and the insurer’s assessment. Ask about cleaning, testing, belongings, replacement materials, lost rent and the excess separately. Obtain written authorisation where required rather than treating an insurer’s request for a quote as claim approval. Our work assessment and quote describe proposed work; the insurer decides cover.
Long-term residential rent is generally GST-exempt, so a residential landlord cannot assume the GST on cleanup is recoverable merely because an invoice shows it. Short-stay or commercial activity can have different treatment. Income-tax deductions and GST claims are separate questions; ask Inland Revenue or your accountant about your circumstances. The prices on this site include GST in NZD.

What should buyers, sellers and lenders check?
There is no universal requirement that every buyer order a meth test. Decide the investigation and contract conditions with your advisers, taking account of available reports and history. A positive result needs interpretation, a suitable scope if work is required, and allowance for independent testing and repairs. Confirm lender and insurer requirements before going unconditional; no single certificate automatically satisfies every bank.
REA’s September 2026 guidance addresses licensed agents’ disclosure obligations. It requires disclosure of known contamination above 15 µg/100 cm² and disclosure at any level when a prospective buyer clearly shows an interest or asks a specific question about meth contamination; it is not permission to conceal or misrepresent information below a threshold. Private sellers should obtain advice about their own duties. Keep full reports and completed-work records available rather than representing a summary price or one sample as the entire property history.

What about a LIM or belongings left by a former tenant?
A council may hold information about reported contamination or a suspected laboratory, but a LIM is not a complete meth testing history. Ask the relevant council what it holds and obtain actual testing and remediation records. Do not assume a clean LIM proves there has never been contamination or that every privately commissioned result is automatically entered on it.
Abandoned goods remain subject to tenancy rules; they cannot all be discarded just because meth is suspected. Follow the required assessment and handling process, including relevant testing or cleaning costs when evaluating goods. Ownership, value and contamination decisions should be documented. Consult Tenancy Services before disposing of or transferring items, particularly where there is a dispute.

How do commercial premises, vehicles and sheds differ?
Residential tenancy thresholds do not automatically determine every workplace, vehicle, caravan or farm-building decision. Identify how the property is used, who controls access, the tested surfaces, other hazards and any contractual or workplace requirements. A sampling plan for rooms in a house may not answer the relevant question for machinery, stock, upholstery or a vehicle.
A commercial project needs a documented sampling question and a method appropriate to the surfaces and activities. Identify who will authorise access and work, how unaffected operations are separated, where removed materials are handled and what evidence is needed for reopening. Keep the building owner, manager and tenant business informed of limitations and remaining repairs; a residential price example does not establish the commercial scope.
For a business, agree staff and customer exclusions, sensitive equipment protection, access, utilities, waste, verification and phased reopening. Coordinate the business, building owner and contractors where duties overlap. Ask whether a provider has experience and equipment suited to the particular setting. Tell us about the property type, findings and proposed work. Before booking, we confirm whether the project suits our service and what specialist involvement is required.

How should reports and property details be shared?
Use the private enquiry form for an existing report, property location and photographs. Identify the owner or authorised contact and tell us who should receive the quote and updates. Avoid unnecessary occupant names, identity documents or personal items in photographs. Our privacy page explains handling of enquiries and files.
Agree who receives the quote, reports and updates, and use appropriate channels for property information. Keep records accurate and provide information where legally required. Privacy arrangements must allow those disclosure duties to be met.
