ERMA report on safety of CCA treated timber valuable
An Environmental Risk Management Report finding that CCA treated timber has been used for many years in New Zealand
without discernable health effects makes valuable points about the safe use and handling of the product, Carter Holt
Harvey said today.
Devon McLean, CHH Chief Operating Officer believed it was important that new research and literature regarding CCA
treated timber was independently reviewed following debates about the product in the United States, and ERMA was the
appropriate scientific body to do this.
“CCA has been a registered timber treatment in New Zealand for over 50 years. We are pleased this thorough report did
not find any evidence of health effects from the use of CCA treated timber here though it does provide a timely reminder
of the need for care in its use and handling,” Mr McLean said.
CCA is currently one of the most effective timber preservation treatments against insect attack and rot caused by fungal
decay. It is commonly used in poles, fence-posts, building foundations and piles, decking, horticulture, and in
landscaping such as retaining walls, and pergolas.
“We recognise that the use of CCA treated timber in play areas is an area of potential concern. Although the ERMA report
found no evidence of health effects from its use, we will continue to provide advice on existing alternatives to CCA as
required and we continue to support industry initiatives to develop timber treatments for these areas.”
“We will also continue our education and training programmes for customers and staff on the correct use and handling of
CCA treated timber. Carter Holt Harvey wants to ensure this highly effective timber treatment continues to be used
safely in New Zealand.”
