What a mess.
The NZ Standard, NZS8510:2017, was introduced in 2017 with a level of 1.5 micrograms.
The Gluckman Report came out in 2018 recommending a level of 15.0 micrograms.
MBIE have been working on this since 2019 and a level was supposed to come into law under the RTA in 2021 – but, if rumours are to believed, MBIE can’t find a Toxicologist to support a level of 15.0 micrograms.
In the meantime it is pretty simple. Use the NZ Standard level of 1.5 micrograms. And use an Insurance company that uses the NZ Standard level of 1.5 micrograms.
If you use the NZ Standard a tenant can’t take you to the Tenancy Tribunal for renting out a Meth Contaminated property.
If you have an Insurance Company that wont decontaminate your property that is at a level between the NZ Standard and the Gluckman Report, between 1.5 and 15.0 micrograms, and your tenant takes you to the Tenancy Tribunal you are likely to lose. So use the NZ Standard.
MBIE needs to hurry up and clear up this mess!!
