The Real Estate Institute wants clarification on meth testing of houses

They want immediate guidance on what to do when dealing with their clients in terms of disclosure.

Chief executive Bindi Norwell says consumers are extremely sensitive about purchasing a property that has been contaminated by meth and the same is true for those looking to rent.

She says they are surprised by today's report on methamphetamine standards which appears to advocate a safe level of 15 milligrams ... when the Ministry of Health and ESR scientists just last year recommended a safe level of 1.5 milligrams.

She says today's figure sees a 900 percent increase in the level that is deemed to be safe.
