The National Measurement System
New Zealand's standards and conformance infrastructure
The standards and conformance infrastructure consists of a number of autonomous organisations with specific and separate responsibilities which cooperate to ensure a coherent system. The National Measurement System is part of this infrastructure.
MSL has primary responsibility to provide measurement standards in accordance with the International System (SI) of units. Our calibration services are accredited to ISO/IEC 17025 by International Accreditation New Zealand (IANZ).
Trading Standards is responsible for legal metrology and, unlike MSL, has enforcement powers under its legislation. Trading Standards source its measurement traceability from MSL and operates calibration laboratories accredited to ISO/IEC17025 by IANZ.
International Accreditation New Zealand (IANZ) is the national authority for the accreditation of testing and calibration laboratories. MSL has a memorandum of understanding with IANZ to advise on all matters related to measurement traceability.
Standards New Zealand (SNZ) is the national standards body and also operates the Technical Barriers to Trade Enquiry Point on behalf of the Ministry of Foreign Affairs.
The Joint Accreditation System of Australia and New Zealand (JAS-ANZ) provides accreditation for conformity assessment bodies in the fields of certification and inspection.
