METH TESTING FOR CONTAMINATION IN DUNEDIN BUILDINGS AND HOMES DURING BUILDING INSPECTION. IF YOU FOLLOW MEDIA REPORTS ON METH USE IN NZ YOU’LL READ THAT JUST ONE SESSION SMOKING THE CLASS A DRUG, ALSO KNOWN AS P OR ICE, COULD BE ENOUGH TO PRODUCE A POSITIVE TEST RESULT IN A HOME.
What Are You Really Buying?
No national testing standards (2015) are a serious problem facing buyers, sellers, agents, landlords, tenants and inspectors.
Housing New Zealand's most up-to-date data shows 688 of its properties tested positive for meth between June 1, 2015 and May 27, 2016. This is a 200 per cent increase compared to the previous financial year, when 229 houses tested positive.
National Poisons Centre toxicologist Dr Leo Schep says "there's a big difference between living in a house where someone smoked methamphetamine, and living in a house that was used to manufacture the drug"
It may be that laboratory tests, where samples are taken from a number of areas in the house (ideally every room), are the most reliable option.
There's no current legal standard for the levels of methamphetamine that make a house uninhabitable, however Ministry of Health guidelines from 2010 establish an acceptable level of less than 0.5 micrograms per 100 sqm.
You have several options when it comes to contamination tests: laboratory tests, professional test kits, and at-home test kits.
If requested during your Dunedin Building Inspection HouseTest.co.nz may use an at-home test kit to test for Meth. The results should be considered presumptive and a positive result will need to be confirmed by laboratory testing.
