Asbestos Analytical & Environmental Consulting 04 566 3311


CES has been carrying out IANZ accredited asbestos services in the Wellington region and throughout New Zealand for more than twenty five years. We have records of analysis dating back to the 1970's complimented by an extensive knowledge of asbestos related issues for many commercial, industrial and residential properties. Because asbestos service related skills have been commonly difficult to obtain, over the years we have developed and implemented a robust and documented internal training programme for all our staff many of whom now work in other aspects of the asbestos industry. The public health issues of asbestos and the consequences of poor management of asbestos materials are well known, we believe in providing quality services that demonstrate best practice, meet the requirements of legislation and internationally recognised standards, and are most importantly cost effective. Feel free to contact us at any time.
