OPPA 2023: New Zealand's Organic Certification Law
OPPA 2023 (Organic Products and Production Act) is New Zealand's first mandatory organic certification law, requiring all businesses making organic claims to hold MPI operator approval by 31 March 2028. Approximately 2,000 NZ businesses will need approval. Small producers earning under $10,000/year are exempt from approval but must still meet the National Organic Standard.

How to Prepare for OPPA Compliance
Audit Your Current Claims
Review all products making organic claims. Identify which products need certification and which suppliers need verification.
Choose a Certification Body
Select an MPI-recognised agency. For exports: BioGro or AsureQuality (IOAS-accredited). For domestic only: OrganicFarmNZ, Demeter (biodynamic), or Hua Māori. Allow 6-12 months for initial certification.
Verify Supplier Certifications
Ensure all organic ingredient suppliers have valid certificates. Document verification for audit trail.
Implement Traceability Systems
Establish systems to track organic products through your supply chain, from receipt to sale.
Update Labeling
Review and update product labels to comply with NZ NOS requirements and any export market standards.
Train Staff
Ensure all relevant staff understand organic handling requirements and documentation procedures.
Frequently Asked Questions
Is there a small producer exemption?
Yes. Businesses earning under $10,000 per year from organic product sales are exempt from MPI approval requirements. However, they must still comply with the National Organic Standard and notify MPI of their exempt status. Restaurants and retailers selling only pre-packaged organic products are also exempt.
What about farmers' market vendors?
Farmers' market vendors making organic claims must comply with the National Organic Standard. Those earning $10,000+ annually from organic sales must be MPI-approved operators. Those earning less are exempt from approval but must still meet the Standard and notify MPI.
Can I use existing BioGro or AsureQuality certification?
Yes, existing certifications from MPI-recognised agencies (BioGro, AsureQuality) will be recognised under OPPA. Ensure your certification remains current through the transition period.

OPPA is the law. The NOS is the rulebook. Here's a clear breakdown.
Active MPI Consultations
MPI is releasing detailed OPPA requirements through a series of notices. Key upcoming requirements include:
- Tranche 2 — Export Documentation: Official Assurance (OPP 124) and Statement of Compliance (OPP 125) forms will be required for every organic export consignment.
- Tranche 3 — Organic Management Plans (under consultation): Operators will need formal OMPs including responsible individual registers, service provider management, import assessment procedures, and mass balance reconciliation.
These requirements are not yet in force. ANZOC is tracking these developments and building platform support as requirements are finalised.
