A misfuel occurs when the wrong type of fuel is accidentally put into a vehicle. The most common is putting petrol into a diesel vehicle, or vice versa. This can cause severe damage to the fuel system and engine.

DO NOT START THE ENGINE. Starting the engine will circulate contaminated fuel throughout the system, causing extensive damage. Contact a NZIFDA-certified operator immediately for professional remediation.

Look for operators displaying the NZIFDA Mark on our homepage. Only operators and workshops carrying the NZIFDA Mark are authorized to provide misfuel remediation services. Compliant Operators (who carry the NZIFDA Mark) receive customer inquiries and allocate work to Certified Workshops in their network.

Certified operators must meet all NZIFDA standards including proper fuel extraction, system remediation, component replacement, waste management, insurance requirements, and documentation standards. See our Industry Standards page for details.

Costs vary depending on the vehicle and extent of contamination. Certified operators must provide transparent, upfront pricing. Always get a written quote before work begins.

All certified operators must provide a comprehensive warranty covering the remediation work. This should be in writing and cover all components and work performed.

Yes. Under New Zealand law, you as the generator of contaminated fuel are responsible for ensuring it is handled by properly licensed operators. If you use an illegal or unlicensed operator, you may face fines and penalties for using unlicensed waste disposal services, liability for environmental violations if waste is improperly disposed, responsibility for cleanup costs if environmental damage occurs, and voided insurance coverage. Always verify operators display the NZIFDA Mark before engaging services.

Illegal operators face severe penalties including: fines up to $600,000 under Fair Trading Act for misleading claims, fines up to $300,000 under Resource Management Act for improper waste disposal, fines up to $100,000 under Dangerous Goods Act for operating without licenses, potential imprisonment for serious violations, and EPA enforcement actions. NZIFDA reports all illegal operators to WorkSafe New Zealand, the Environmental Protection Authority (EPA), and local authorities for enforcement action.

Use our Report Violation form to report any operator who fails to meet NZIFDA standards or engages in non-compliant practices. NZIFDA reports all illegal operators to WorkSafe New Zealand, the Environmental Protection Authority (EPA), and relevant local authorities for enforcement action.

Yes, mobile operators CAN be certified by NZIFDA, but they must meet strict requirements. However, there are currently no compliant mobile services that have achieved NZIFDA certification. Mobile operators must: (1) Operate under a Compliant Operator license, (2) Have each vehicle individually assessed and certified, (3) Meet all Dangerous Goods transport requirements, (4) Complete annual recertification ($2,500 + GST per annum), and (5) Maintain proper waste tracking, insurance, and compliance systems. For consumers: Only use operators displaying the NZIFDA Mark. Currently, this means using certified fixed facilities. If a mobile operator cannot show you the NZIFDA Mark, you cannot verify their compliance and should not use their services. Learn more about what "certified" actually means.

Mobile extraction services face significant compliance challenges that make certification difficult: (1) Waste tracking must begin at the point of generation, which for mobile services would be at uncontrolled locations like fuel stations or roadsides, (2) Transporting contaminated fuel from uncontrolled locations triggers full Dangerous Goods transportation requirements that are extremely difficult to comply with for mobile operations, (3) Environmental protection and spill containment cannot be properly ensured at variable, uncontrolled locations, (4) Each vehicle must be individually assessed and certified, (5) Annual recertification is required. While mobile operators CAN be certified if they meet these requirements, currently none have achieved certification. Fixed facilities provide controlled environments with proper containment, documentation systems, and emergency response equipment readily available, making compliance verification much more straightforward.

NZIFDA operates a two-tier certification structure with three certification types. See our Certification Process page for complete requirements:

Operators must comply with EPA Hazardous Substances Regulations, Dangerous Goods Act, MfE waste disposal guidelines, Health and Safety at Work Regulations, and Fuel Industry Act. See our Resources page for details.

Yes. Contaminated fuel is classified as hazardous waste and must be disposed of per MfE guidelines with complete tracking documentation. Certified operators handle this properly.

Certified operators must maintain minimum $2M professional indemnity insurance and $5M public liability insurance. See our Certification page for details.

Certified operators undergo regular compliance audits and must renew certification annually. We also investigate all reported violations.
