TDDA, Level 1, 19, Byron Avenue, Takapuna, Auckland

The Drug Detection Agency (TDDA) is Australasia’s complete solution provider for all workplace drug policy, education and testing needs. Our end-to-end services provide our clients with a level of comfort in relation to creating a safer workplace together.

TDDA started in 2005, and was conceived in order to supply a specialised service to companies that were conducting workplace drug and alcohol testing or looking at doing so within their own organisation.

In March 2008, the Standard AS/NZS 4308:2008 was released after TDDA had submitted public comment in respect of on-site screening. Over the ensuing years TDDA worked diligently to ensure compliance to the drug testing Standard and in August 2010 became the first workplace drug testing company in New Zealand to have received International Accreditation of New Zealand (IANZ) ISO 15189 accreditation to the AS/NZS 4308:2008 drug testing Standard. Proving our dedication and quality to our customers, TDDA went on to have each of our 20 offices around New Zealand independently accredited by IANZ under ISO 15189. Making TDDA the only truly nationally accredited organisation throughout New Zealand.

In 2011, after strong demand from our clients to have the same high quality service for their Trans Tasman operations, TDDA expanded into Australia. To ensure we met our clients expectations TDDA worked hard to replicate our systems and processes and were pleased to announce gaining further accreditation from the National Association of Testing Authorities (NATA) within our Australian operations.

This has been significant for both TDDA and our clients, as we are now the only New Zealand and Australian drug testing provider to have received accreditation from both IANZ and NATA respectively for both AS/NZS 4308:2008 (NZ, Aus) and AS 4760-2006 (Aus) drug testing Standards.

TDDA now comprises 40 branches throughout Australia and New Zealand with specialist on-site testing vehicles and qualified collecting and screening staff providing a truly international service.

Our team is extremely knowledgeable about the illicit drug industry and its negative effects. With over 10 years of operation TDDA has forged an excellent reputation with our clients through our world-class services.
