Testing for methamphetamine in premises
7 Requirement on landlord to test for methamphetamine in premises
(1)
This regulation prescribes a requirement on the landlord for the purposes of sections 45(1)(bd) and 66I(1)(bc) of the Act.
(2)
A landlord must arrange for testing for methamphetamine at the premises in accordance with the prescribed method of testing set out in regulation 9 if—
(a)
the New Zealand Police or a local authority notifies the landlord that the manufacture of methamphetamine has, or is likely to have, taken place at the premises; or
(b)
the results of a valid screening assessment (see regulation 8) carried out by any person indicate that the premises are contaminated with methamphetamine, and the landlord is notified of this.
(3)
The landlord must comply with subclause (2) as soon as practicable following the landlord being notified as set out in subclause (2)(a) or (b), as applicable.
8 Meaning of valid screening assessment for methamphetamine in premises
(1)
For the purposes of regulation 7(2)(b), a valid screening assessment means a screening assessment that complies with subclause (2).

(b)
the requirements relating to the competencies and independence of the screening sampler apply to the person carrying out the screening assessment only if that person is paid for carrying out the assessment. If the person is paid but does not meet the competencies described in section 7.1, they may be treated as complying with those competencies if they instead meet the competencies described in section 7.2:
(c)
National Institute for Occupational Safety and Health field composite testing is not an approved sampling technique for the purpose of section 3.2.3.2 (despite Table 1 listing it as an approved method for screening assessments). Consequently, Appendix A2.2 does not apply:

(e)

(f)
section 3.2.6(i) does not apply and instead the screening assessment report must include a conclusion confirming whether the results of the screening assessment indicate that the premises are contaminated with methamphetamine.

There are no transitional, savings, or related provisions in these regulations as made.

Explanatory note
This note is not part of the regulations but is intended to indicate their general effect.
These regulations, which come into force on 16 April 2026, are made under the Residential Tenancies Act 1986 (the Act) and provide a process for identifying and managing methamphetamine contamination in residential tenancy premises.
The regulations do the following:
prescribe a maximum acceptable level of methamphetamine, above which the premises will be considered contaminated for the purposes of the Act:
prescribe a maximum inhabitable level of methamphetamine, above which the special rules in section 59B of the Act for terminating a tenancy apply:
prescribe a method of testing to be used to determine whether methamphetamine is above the maximum acceptable level or maximum inhabitable level. The regulations incorporate the detailed assessment method of testing set out in New Zealand Standard 8510:2017, with specified modifications:
require the landlord to carry out the prescribed testing method if the landlord is notified by police or a local authority of likely methamphetamine manufacture in the premises or an initial screening assessment indicates that methamphetamine may be present above the maximum acceptable level:
prescribe a decontamination process that the landlord must complete before providing the premises to a tenant or if continuing to provide the premises to a tenant:
require the landlord to complete the decontamination process as soon as practicable if decontamination is carried out while continuing to provide the premises to the tenant. The regulations incorporate the decontamination procedures set out in New Zealand Standard 8510:2017, with specified modifications:
provide a process for dealing with goods left by the tenant on premises contaminated by methamphetamine. The process follows the standard process in the Act for dealing with abandoned goods with some modifications to reflect the additional risks and costs of dealing with contaminated goods.
