IANZ accredited inspection services

ISO/IEC 17020 is an internationally recognised standard for organisations that perform inspection activities. Accreditation demonstrates that an inspection body has been independently assessed and found competent to carry out specific inspection services in accordance with documented procedures, quality management systems, and internationally recognised requirements.

International Accreditation New Zealand (IANZ) is New Zealand's national accreditation body. IANZ independently assesses organisations against internationally recognised standards to verify technical competence, quality systems, and ongoing compliance with accreditation requirements.

Being IANZ accredited means an organisation has undergone a rigorous independent assessment of its people, processes, systems, and technical capabilities. Accredited organisations are also subject to ongoing surveillance and reassessment to ensure standards continue to be maintained.

Our ISO/IEC 17020 accreditation covers asbestos and methamphetamine inspection services, including:

• Asbestos Management, Refurbishment and Demolition Surveys
• Asbestos Air Monitoring and Clearances
• Methamphetamine Testing

Please refer to our official Scope of Accreditation for the full list of accredited activities.

Accreditation provides confidence that inspections are completed by competent personnel using documented methodologies, quality controls, and independently assessed systems. It reduces risk and provides greater assurance that inspection outcomes are reliable, consistent, and defensible.

Not all asbestos surveys in New Zealand are required to be completed by an accredited inspection body. However, accreditation provides independent assurance of technical competence and quality management and is increasingly reconised as best practice by many organisations and procurement teams.

Accreditation and licensing serve different purposes.
Accreditation assesses the competence of an organisation and its inspection systems against an international standard.
Licensing is issued to individuals and organisations under New Zealand health and safety legislation and authorises specific asbestos-related activities.
ALS Environmental Risk Services NZ maintains both accredited inspection services and appropriately qualified and licensed personnel where required.

Accredited organisations are subject to regular surveillance assessments and periodic reassessments by IANZ. Accreditation is not a one-time approval and requires ongoing demonstration of competence and compliance.

Accreditation does not guarantee a particular inspection outcome. However, it provides assurance that inspections are completed using independently assessed systems, competent personnel, and recognised quality processes designed to deliver accurate and consistent results.

For organisations managing multiple sites, accreditation provides consistency across inspections, standardised reporting, documented quality controls, and confidence that inspection activities are being undertaken in accordance with recognised standards.

Accreditation provides independent evidence of technical competence and quality assurance, helping procurement teams evaluate suppliers and demonstrate due diligence when selecting inspection providers.

An asbestos survey identifies and assesses asbestos-containing materials within a building. An asbestos management plan uses the survey findings to document how asbestos risks will be managed and controlled over time.
