New Zealand’s drone regulatory landscape changed decisively on 22 December 2025. Through amendments to Civil Aviation Rules Part 101 and Part 102, the government explicitly removed agricultural spraying, topdressing, and vertebrate toxic agent (VTA) application from the low-risk Part 101 framework. What was previously implied by practice is now written in black and white: these operations must be conducted under a Part 102 Unmanned Aircraft Operator Certificate (UAOC)—regardless of the aircraft’s weight.
For importers bringing Chinese-manufactured agricultural spraying drones into New Zealand, this regulatory clarification has profound implications. The drone may physically clear Customs, but it cannot legally fly a single commercial spraying mission until a chain of aviation, agricultural, and biosecurity requirements is satisfied. This article provides a detailed, compliance-focused roadmap for navigating that chain in 2026.
⚠️ Key point: “Entering the country” and “legally operating” are two completely different milestones. This guide addresses both.
1. The Regulatory Shift: What Changed on 22 December 2025
1.1 Before vs. After
Prior to the amendment, agricultural spraying sat in a grey zone—practitioners understood it required Part 102, but the rule text did not state this explicitly. The 2025 amendment removes all ambiguity:
| Activity | Before 22 Dec 2025 | From 22 Dec 2025 |
|---|---|---|
| Aerial spraying of agrichemicals | Required Part 102 (by practice) | Expressly prohibited under Part 101; must hold Part 102 |
| Aerial topdressing | Required Part 102 (by practice) | Expressly prohibited under Part 101; must hold Part 102 |
| VTA application | Required Part 102 (by practice) | Expressly prohibited under Part 102; must hold Part 102 |
| Surveying and mapping | Permitted under Part 101 | Still permitted under Part 101 |
| Certain night operations | Generally prohibited under Part 101 | Permitted where a Transport Instrument allows, under conditions |
| BVLOS in controlled environments | Required Part 102 approval | May proceed under Transport Instrument conditions |
1.2 Why This Matters for Chinese Imports
The amendment does two things that directly affect importers of Chinese drones:
-
It eliminates any hope of operating under Part 101 as a workaround, even for sub-25 kg aircraft. The CAA’s guidance is explicit: “even if your drone weighs less than 25 kg fully loaded, you will still need a Part 102 Unmanned Aircraft Operator Certificate”.
-
It signals stricter CAA scrutiny of imported equipment. When a drone is imported from overseas, the CAA requires it to be inspected before it is flown. The rule clarification strengthens the CAA’s hand in demanding thorough documentation and physical verification.
1.3 The Legal Architecture
Three pieces of law govern your operation:
-
Civil Aviation Act 2025 / Part 102 — governs the aircraft, the operator, and the flight
-
Agricultural Compounds and Veterinary Medicines (ACVM) Act 1997 — governs the pesticide you spray
-
Resource Management Act 1991 / Hazardous Substances and New Organisms Act 1996 — govern environmental discharge and hazardous substance handling
A Chinese drone that satisfies aviation rules but sprays a non-authorised agrichemical is still operating unlawfully. All three layers must be satisfied simultaneously.
2. Step One: Specifications to Lock Down Before Manufacturing
2.1 Gross Mass Is the Threshold That Triggers Automatic Part 102
A drone with a gross mass (including batteries and chemical payload) greater than 25 kg always requires Part 102 certification—this is independent of the spraying activity itself. Most Chinese agricultural spraying drones with 20–40 litre tanks exceed this threshold when fully loaded.
Action item: Obtain from your manufacturer a documented maximum takeoff weight (MTOW) that accounts for batteries, full tank, and spray system. This figure determines:
-
Whether Part 102 is mandatory (it is, for spraying, regardless)
-
The level of CAA inspection rigour
-
The structure of your exposition’s maintenance and airworthiness procedures
2.2 Documentation the CAA Will Expect
Under Part 102 rule 102.11, your exposition must address aircraft specifics, including “details of the number and specifications of the aircraft to be used” and “procedures to establish initial airworthiness, and any standards applied”. For an imported Chinese drone, you must obtain:
-
Full technical specification sheet in English, detailing the flight controller, electronic speed controllers, motors, and propulsion system
-
Maintenance manual with scheduled inspection intervals for booms, nozzles, pumps, and batteries
-
Certificate of Conformity from the manufacturer
-
Materials Safety Data Sheets (MSDS) for all chemical-contact components (tank, hoses, seals)
-
Component traceability documentation — the CAA inspector will want to verify that critical parts are identifiable and replaceable
-
Software/firmware documentation — version history, fail-safe behaviours, geofencing capabilities, and data logging formats
-
English-language flight control software that functions without dependency on China-only servers
💡 A Chinese drone with no markings, no English manuals, or heavily modified/custom firmware is a red flag for CAA inspectors. Such an aircraft is highly likely to be rejected during the initial airworthiness inspection.
2.3 Radio Compliance for New Zealand Spectrum
New Zealand’s radio spectrum is managed by Radio Spectrum Management (RSM) under the Ministry of Business, Innovation and Employment. Agricultural drones typically use 2.4 GHz and 5.8 GHz for control links. Confirm with your manufacturer that radio modules:
-
Operate within New Zealand’s legal power limits
-
Are configurable to NZ-legal frequencies
-
Hold FCC/CE markings as reference points for emissions compliance
Non-compliant transmitters can be seized at the border or require an RSM licence.
3. Step Two: Customs Clearance — Getting the Drone Physically into New Zealand
3.1 No Import Permit Required for the Drone Itself
Unlike some countries, New Zealand does not require a special import permit for drones. You can bring a drone through Customs without special permits, and there are no restrictions on importing drones for commercial use. However, the following still apply:
Tariff Classification: Agricultural spraying drones typically fall under HS Code 8806.22 (unmanned aircraft, MTOW ≤ 250 kg). The MFN tariff rate is 0%, meaning no customs duty is payable on the drone itself.
GST: 15% GST applies to the CIF (Customs, Insurance, Freight) value. If importing as a GST-registered business for taxable supplies, you can reclaim it via your GST return.
Declaration: Accurate commercial invoice, packing list, bill of lading/air waybill, and certificate of origin. Engage a licensed Customs broker for commercial shipments.
3.2 Lithium Battery Transport — The Most Common Bottleneck
Spraying drones use high-capacity lithium-polymer batteries, classified as Dangerous Goods Class 9 for transport. This is the single most common cause of import delays. Requirements:
-
Batteries must be UN 38.3 certified
-
Proper DG documentation (IATA for air, IMO for sea)
-
Correct packaging per DG regulations
-
Supplier must declare batteries accurately on the shipping manifest
Incorrect DG documentation routinely results in entire shipments being returned to origin. Build 2–4 extra weeks into your timeline for this risk.
3.3 The Critical Distinction: “Cleared” ≠ “Legal to Fly”
Customs clearance gives you physical possession of the drone in New Zealand. It does not authorise a single spraying flight. The aviation and agricultural compliance chain must be satisfied separately.
4. Step Three: Part 102 Certification — The Core Compliance Gate
4.1 Understanding the UAOC
The Part 102 Unmanned Aircraft Operator Certificate is issued to an organisation or company, not an individual. It certifies that the organisation has:
-
Conducted an adequate risk assessment for the proposed operation
-
Developed procedures to manage those risks
-
Documented everything in an Exposition — a formal, detailed operations manual
-
Identified a person with primary responsibility for the operation
-
Established maintenance and continued airworthiness procedures
-
Defined personnel licensing, training, and competency requirements
4.2 The Exposition: Your Most Important Document
Rule 102.11 specifies exactly what the exposition must address:
| Exposition Element | Specific Requirement for Spraying Drones |
|---|---|
| Hazard register | Chemical drift, payload release failures, overflight of people, environmental contamination |
| Risk mitigation | Buffer zones, weather minima, emergency procedures, spill response |
| Aircraft specifications | MTOW, tank capacity, nozzle types, flow rates, RTK GPS accuracy |
| Initial airworthiness | CAA inspection procedure, documentation review, physical verification |
| Maintenance procedures | Scheduled inspections, component replacement criteria, battery management |
| Personnel competency | Part 102 Pilot Certificate, Pilot Chemical Certificate, Agricultural UAV Rating |
| Cargo/drop procedures | Chemical loading, payload release mechanisms, pre-flight calibration |
| Operating procedures | Minimum distances from persons/property, weather limits, record-keeping |
A poorly prepared exposition means multiple rounds of CAA review, each billed at an hourly rate. The financial and timeline cost of rework is substantial.
4.3 The Aircraft Inspection Requirement for Imported Drones
This is the provision most specific to your situation: if you import an agricultural/spray drone from overseas, the CAA will require that it is inspected before it is flown.
The inspection verifies:
-
The physical aircraft matches the specifications in your exposition
-
Safety-critical systems (emergency stop, payload release, fail-safe modes) function as documented
-
Build quality and component traceability meet CAA expectations
-
Maintenance documentation is adequate to support continued airworthiness
-
Software integrity can be verified
4.4 Adding the Aircraft to Your Operations Specifications
Your UAOC comes with an Operations Specifications document listing approved aircraft. Before you fly any specific drone, it must be listed there. Importing a second drone or upgrading models requires a separate CAA application to amend the Operations Specifications.
4.5 Timeline Realities
| Phase | Duration | Notes |
|---|---|---|
| Exposition preparation | 4–6 weeks | Writing, review, refinement |
| CAA review of UAOC application | 8–10 months | Current CAA processing time |
| Part 102 Pilot Certificate | 2–4 weeks | Can run concurrently with UAOC application |
| Pilot Chemical Certificate | 1–2 weeks | Required for aerial application; Growsafe RCA may substitute |
| Operational Competency Assessment | 1–2 days | Requires UAOC in place |
| Agricultural UAV Rating | 1–2 weeks | Practical endorsement after OCA |
| CAA aircraft inspection | 2–4 weeks | Scheduled after UAOC issuance |
| Total realistic timeline | 10–12 months | To reach provisional Agricultural Rating |
⚠️ Starting the UAOC application late can add months to your timeline. Since CAA queues applications for 8–10 months, submit the exposition first; all other certifications can run concurrently.
4.6 Interim Solution: Operating Under an Existing UAOC
You do not have to wait for your own UAOC to begin commercial operations. It is legitimate to operate under an established operator’s UAOC while your application is in process. This allows revenue generation during the waiting period. Once your UAOC is approved, you transition to operating under your own certificate.
5. Step Four: Pilot Qualifications — The Four Certificates
Under a Part 102 UAOC for agricultural spraying, every pilot must hold four qualifications:
5.1 Part 102 Professional Pilot Certificate
Personal flying qualification covering theory and practical flight test, including ATTI mode flying (GPS and optical positioning disabled) to prove capability if positioning fails mid-operation.
5.2 Pilot Chemical Certificate
Specifically designed for aerial application. Covers:
-
How spray behaviour from a drone differs from ground-based application
-
Drift management
-
Safe chemical handling in the air
A standard Growsafe Approved Handler or Registered Chemical Applicator (RCA) certificate alone is not sufficient. However, if you already hold a Growsafe RCA, you may be exempt from portions of the Pilot Chemical Certificate — seek advice before enrolling.
5.3 Operational Competency Assessment (OCA)
Practical sign-off assessed against the specific procedures in the UAOC you operate under. Cannot occur until the UAOC exists.
5.4 Agricultural UAV Rating
Spray and spreading-specific endorsement covering:
-
Practical ag drone operation
-
Flight planning for application
-
Calibration
-
Spray coverage considerations
-
Product placement precision
After the provisional Agricultural Rating, a full rating follows a probationary period of 30 supervised flights and/or 6 months.
6. Step Five: Agrichemical Compliance Under MPI/ACVM
6.1 The ACVM Act Requirement
Under the Agricultural Compounds and Veterinary Medicines Act 1997, you must import, manufacture, sell, or use only authorised agricultural compounds. “Authorised” means the product is:
-
Registered under ACVM (individual product assessment), or
-
Exempt from registration (certain product groups), or
-
Approved for special circumstances under strict conditions
6.2 Label Compliance Is the Law
The product label is your legal constraint. You may only use the agrichemical:
-
For the crop and pest specified on the label
-
At the application rate specified
-
With the buffer zones specified
-
Using application methods the label permits
Before importing your drone, verify that the agrichemicals you intend to use are approved for aerial application and that their labels permit drone-based spraying.
6.3 Record-Keeping Obligations
Operators must maintain detailed records of every spraying operation:
-
Date, time, and location
-
Product name and batch number
-
Application rate and total volume
-
Weather conditions
-
Name of applicator
Records must be retained for a minimum of three years and made available to MPI on request.
6.4 Regional Council Rules
Sixteen regional councils across New Zealand enforce their own rules on agrichemical discharge under the Resource Management Act. Key examples:
-
Canterbury: Strict rules near waterways; resource consent may be required
-
Auckland: Specific buffer zones near residential areas and ecological sites
-
Waikato: Rules on spraying near roads and public spaces
Many councils now accept drone spraying as a lower-drift alternative, but you must demonstrate compliance with local plans. Contact your regional council before your first commercial flight.
6.5 The Four Laws Governing Agrichemical Use
| Legislation | Focus |
|---|---|
| Resource Management Act 1991 | Controls discharge of agrichemicals into the environment |
| Hazardous Substances and New Organisms Act 1996 | Identifies and manages hazards of agrichemicals |
| ACVM Act 1997 | Manages risk through registration and residue limits |
| Health and Safety at Work Act 2015 | Prevents harm to people at or near work sites |
All four apply simultaneously when you operate a spraying drone.
7. Step Six: Insurance and Liability
7.1 Aviation Liability Insurance
Standard farm policies exclude aviation liabilities. You need specialist aviation insurance covering:
-
Third-party liability
-
Environmental liability (chemical drift)
-
Hull insurance (the drone itself)
7.2 Public Liability for Spraying Services
If offering spraying services to third parties, ensure your public liability policy explicitly covers aerial agrichemical application. Insurers often treat this as high-risk and may exclude it without a specific endorsement.
8. Common Pitfalls in Importing Chinese Agricultural Drones
8.1 “I’ll Fly Under Part 101”
Not legal since 22 December 2025. Part 101 now explicitly prohibits agricultural spraying. Operating without Part 102 is an offense under the Civil Aviation Act with penalties including fines, equipment confiscation, and prosecution.
8.2 Buying Without Verifying CAA Acceptability
Not every spray-capable drone is CAA-inspectable. Drones with:
-
Undocumented flight controllers
-
No maintenance manuals
-
Poor build quality or unverifiable components
-
Heavy custom firmware modifications
…are likely to be rejected during inspection. Before purchasing, ask the manufacturer:
-
Can they provide full English documentation?
-
Have they supplied drones to other New Zealand operators who successfully obtained Part 102 certification?
-
Can they provide component traceability and MSDS for chemical-contact parts?
8.3 Ignoring Battery Shipping Regulations
Lithium batteries are Dangerous Goods. Incorrect DG documentation results in shipment return, costing 3–6 weeks plus freight fees. Verify your supplier’s DG compliance credentials before ordering.
8.4 Underestimating the Part 102 Timeline
8–10 months for CAA to approve a new UAOC application. Ordering in October expecting to spray in November is unrealistic. Plan 12 months ahead minimum.
8.5 Software Connectivity Assumptions
Confirm that:
-
The drone’s software is available in English
-
It functions without access to China-only servers
-
You can export flight logs in a format you can store and retrieve for compliance
Cloud-dependent systems that route through Chinese servers may create compliance and data sovereignty concerns.
8.6 Overlooking Initial Airworthiness Procedures
Part 102 rule 102.11(12) specifically requires “procedures for establishing initial airworthiness, and any standards applied”. Your exposition must describe how a newly imported drone is verified before its first flight. The CAA inspection of imported equipment is part of this—but your exposition must document the broader framework.
9. The Complete Import-to-Operation Pathway
| Phase | Duration | Key Milestones |
|---|---|---|
| 1. Pre-order specification | 2–4 weeks | Lock down MTOW, obtain documentation commitments from manufacturer, confirm radio compliance |
| 2. Order & manufacture | 2–6 weeks | Production with agreed specifications |
| 3. International shipping | 2–5 weeks | DG-compliant battery transport |
| 4. Customs clearance | 1–2 weeks | Broker submission, GST payment |
| 5. Exposition writing | 4–6 weeks | Concurrent with steps 1–4; submit to CAA early |
| 6. CAA UAOC review | 8–10 months | Application in CAA queue |
| 7. Pilot certifications | 2–3 months | Part 102 Pilot Cert, Chemical Cert, OCA, Ag Rating (concurrent where possible) |
| 8. CAA aircraft inspection | 2–4 weeks | Physical inspection, add to Operations Specifications |
| 9. MPI/Council compliance setup | 1–2 weeks | Verify product labels, establish records, council consultation |
| 10. First legal commercial flight | — | Full compliance achieved |
Total realistic timeline: 12–15 months from initial order to first legal commercial spray.
10. Strategic Recommendations
10.1 Start with the UAOC Application
Because the CAA queue is 8–10 months, initiate the exposition writing process before you even order the drone. You can specify the exact make and model in the exposition as soon as you finalise the purchase. This parallel processing saves months.
10.2 Engage Expert Help Early
The exposition is the single most critical document. A poorly prepared one triggers multiple CAA review cycles, each billed hourly. Engaging an experienced exposition writer or aviation consultant—while not mandatory—substantially reduces the risk of costly rework.
10.3 Build the Safety Case for Your Specific Aircraft
For an imported Chinese drone, your exposition must make a compelling safety case around:
-
Component traceability and quality assurance
-
Maintenance sustainability (can you get spare parts?)
-
Software integrity and fail-safe behaviours
-
Calibration and chemical application precision
-
Emergency procedures specific to the aircraft’s design
10.4 Consider Operating Under an Existing UAOC Initially
To generate revenue during the 8–10 month CAA wait, operate under an established operator’s UAOC. This requires negotiating arrangements with a certificate holder but is a legitimate and common pathway.
10.5 Maintain Dual Compliance Vigilance
Remember: CAA Part 102 certifies the operation, but MPI ACVM certifies the product. A fully certified Part 102 operation spraying a non-authorised agrichemical is still illegal. Both chains must be continuously satisfied.
10.6 Plan for BVLOS Evolution
Current agricultural spraying typically requires visual line of sight. BVLOS operations require specific CAA approval. As your operation scales, build the safety case for BVLOS early—it requires demonstrating rigorous risk management, redundant communications, and fail-safe procedures. The 22 December 2025 rule changes have created more flexible pathways for BVLOS in controlled environments, signaling regulatory direction of travel.
11. Looking Ahead: Regulatory Trajectory
The New Zealand government has explicitly stated its intent to “back farmers and rural communities by reducing unnecessary regulatory burden”. The creation of Part 107 (regulatory sandboxes for advanced aviation) and the transfer of some technical requirements from Part 101 into more agile Transport Instruments signal a direction toward:
-
Faster rule updates that track technology
-
Greater flexibility for low-risk operations
-
Clearer pathways for high-risk operations like agricultural spraying
-
Potential future frameworks that could streamline certification for proven, lower-risk agricultural drone operations
However, agricultural spraying itself remains firmly in the Part 102 high-risk category. The regulatory clarification of December 2025 was not a loosening—it was a tightening that removed any ambiguity. Importers must plan accordingly.
Conclusion
Importing a Chinese-manufactured agricultural spraying drone into New Zealand under the post-December 2025 regulatory framework is entirely feasible, but it is a project measured in months, not weeks. The drone’s physical entry through Customs is merely the first of many gates. The substantive compliance work lies in:
-
Specifying the right aircraft with documentation the CAA can inspect and accept
-
Writing a robust exposition that makes a thorough safety case for your operation
-
Obtaining the UAOC through the 8–10 month CAA review process
-
Securing the four pilot certificates for yourself and any employees
-
Passing the CAA physical inspection of your imported drone
-
Complying with MPI/ACVM for every agrichemical you spray
-
Satisfying regional council rules for your operating geography
The operators who succeed are those who start early, document thoroughly, and engage expert help where needed. A Chinese-sourced spraying drone can become a productive, compliant, and profitable part of a New Zealand agricultural operation—but only when the full regulatory chain is satisfied.
The 22 December 2025 rule changes removed any grey area: there is no shortcut around Part 102 for agricultural spraying. Plan for it, budget for it, and execute against it systematically.
