ISO 9001:2026: what changed, and what NZ certificate holders need to do by 30 September 2029
ISO 9001:2026 was published on 16 September 2026. Your ISO 9001:2015 certificate does not lapse overnight — but every certified organisation must complete its transition by 30 September 2029, and from 31 March 2028 new certifications can only be issued to the 2026 edition.
Is my ISO 9001:2015 certificate still valid?
Yes, for now. ISO 9001:2026 — the sixth edition — was published on 16 September 2026 and supersedes the 2015 edition, but existing certificates carry on through a three-year transition period. Organisations already certified to ISO 9001:2015 must complete their transition to the 2026 edition by 30 September 2029.
Who set that deadline?
Not ISO. ISO writes standards and does not certify anyone. Transition deadlines come from the accreditation community — since 1 January 2026 that is Global Accreditation Cooperation Incorporated (Global ACI), which succeeded the International Accreditation Forum when it ceased operating. Global ACI’s transition requirements for ISO 9001:2026 are mandatory for the accreditation bodies that sign its arrangement and for the certification bodies they accredit.
Kaizen isn’t a certification body either. We prepare your system and your people; an independent, accredited certification body audits you and issues the certificate.
The transition timeline
What actually changed?
Global ACI describes the revision as building on the established ISO 9001 framework, “with updates intended to improve clarity and usability.” The themes it names are clearer wording; a stronger focus on leadership, quality culture and accountability; greater clarity around risks and opportunities; a new Annex A that clarifies key terms and the intent of requirements; and closer alignment with other ISO management system standards.
The skeleton is unchanged: the same Harmonized Structure that ISO 14001 and ISO 45001 use, clauses 4 to 10 — context of the organization, leadership, planning, support, operation, performance evaluation and improvement. The climate-change wording added to that common text in February 2024, which asks whether climate change is a relevant issue for the organisation, is carried inside the new edition.
What nobody can honestly hand you yet is a clause-by-clause comparison. ISO doesn’t publish one, and the standard itself is a paid document. The reliable route is a gap analysis of your own system against the 2026 text.
How the transition audit works
Your certification body can assess the transition during a scheduled surveillance audit, at your recertification audit, or in a separate transition audit. For most certified businesses the least disruptive option is to line the transition up with an audit that is already in the calendar — which means knowing your audit dates now, not in 2029.
A sensible plan for a certified NZ business
First, find your next surveillance and recertification dates and ask your certification body when it expects to audit to ISO 9001:2026. Second, get the 2026 standard and run a gap analysis against your current system, starting with the themes above. Third, update the system and brief the people who own each part of it. Fourth, run an internal audit to the new edition before the certification body does.
Also certified to ISO 14001? ISO 14001:2026 was published in April 2026 and runs on its own clock: organisations certified to ISO 14001:2015 must transition by 30 April 2029, and new certifications move to the 2026 edition from 31 October 2027. If you run both standards, one gap analysis can cover the two.
ISO 9001:2015 certificates stay valid through the transition, but every certified organisation must be on ISO 9001:2026 by 30 September 2029. The earlier you know your audit dates and your gaps, the more of the work fits into audits you are already paying for.
