National industry standards for misfuel remediation, operator certification, and the National Misfuel Register
The New Zealand Insoluble Fuel Disposal Agency (NZIFDA) is the national industry authority for misfuel remediation. NZIFDA sets and enforces compliance standards, certifies operators and workshops, monitors ongoing compliance, and reports non-compliant operators to enforcement authorities including WorkSafe NZ, the EPA, and regional councils.
Misfuelling — accidentally putting the wrong fuel in a vehicle — requires specialist remediation by certified operators using manufacturer-specified procedures. Improper handling creates environmental, safety, and legal risks for everyone involved.
All misfuel remediation jobs are recorded in the nationally held NZIFDA register. Only operators displaying the NZIFDA Mark have been independently verified.
The Official NZIFDA Mark
The NZIFDA Mark is the nationally recognised standard for misfuel remediation compliance. When a business displays this mark, NZIFDA has independently verified their Dangerous Goods licensing, insurance, waste tracking, environmental compliance, facility standards, staff competency, and manufacturer-specified fuel removal procedures.
If an operator cannot show you the NZIFDA Mark, there has been no independent verification of their compliance. Do not use their services. Report non-compliance.
Don't start the engine. Contact a certified operator immediately. We explain the process and your rights.
What to do now →Certification requirements, compliance standards, and how to join an existing operator network.
Operator information →Your legal obligations under the HSWA, RMA, and Dangerous Goods Act when misfuel incidents occur on your site.
Fuel station obligations →Verify remediation was performed using manufacturer-specified methods by a certified operator.
Insurer information →No vehicle manufacturer on the planet prescribes filler neck extraction. This method forces equipment past anti-siphon safety devices mandated by FMVSS 301 (rollover valves, mesh screens, and complex filler neck geometry), damages safety-critical crash protection components, cannot achieve complete fuel removal due to tank baffles, and voids both manufacturer warranty and insurance coverage.
Every vehicle manufacturer — Toyota, VW/Audi, BMW, Mercedes, Ford, Hyundai/Kia, Nissan, Mazda, GM, Subaru, and all others — prescribes the same two methods:
Fuel Pump Access Panel
Full Tank Removal
All approved fuel removal procedures follow OEM service manual procedures. View manufacturer-specific guidelines in our OEM Standards database.
