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 will attend site, obtain samples and submit samples for lab analysis, a lab certificate will be issued indicating contamination levels within the dwelling.
