:::

Counter-Drone Landscape in New Zealand

Unauthorized drones are an increasingly common concern for property owners, businesses, and critical infrastructure operators. But legal options for defense are limited by regulation, liability, and property law.

The Core Legal Issue:

Who owns the airspace above your property?

• Traditional law: "Ad coelum et ad inferos" (to the heavens and to the depths) – property extends infinitely upward
• Modern interpretation: Property rights extend only to a "reasonable height" for property enjoyment (approximately 80-120 meters AGL)
• Above that height: Airspace is public; no exclusive ownership

Implication: Drones flying above reasonable height may be in technically "public" airspace, limiting property owner remedies :::

Legal Options for Unauthorized Drone Defense

Option 1: Report to Police

When to use: If drone is clearly violating law (harassment, invasion of privacy, stalking) Process:

1. Document incident (date, time, location, drone description, witness names)
2. Record video if possible (without damaging the drone)
3. Contact local Police non-emergency line (or 111 if ongoing threat)
4. File formal report; provide all documentation
5. Police investigate; may identify operator and take enforcement action

Police Investigation:

• Police may confiscate drone if evidence of crime
• Operator may face charges (trespass, harassment, Privacy Act violation)
• If identified, Police can require operator to cease flights

Success rate: Varies; easier if drone operator identified; harder if drone anonymously operated

Option 2: Notify CAA (Civil Aviation Authority)

When to use: Drone violating CAA regulations (Part 101/102 rules) Violations to report:

• Flying without required pilot license/certification
• Operating without airspace approval
• Flying in restricted airspace
• Night operations without authorization
• Over-people operations without approval
• Excessive altitude (above 400 ft AGL)

Process:

1. Document violation details (date, time, location, flight pattern, aircraft description)
2. Note any CAA numbers visible on aircraft (if you could read them)
3. Submit incident report to CAA Investigation team
4. CAA investigates; may pursue enforcement action

CAA Enforcement Options:

• Notice to comply (direct operator to cease)
• Suspension of pilot license (if operator identified)
• Monetary penalty (fine up to NZ$10,000 for Part 101; higher for Part 102)
• Aircraft confiscation (if used in violation)

Success rate: Depends on identification of operator; harder if operator unknown

Option 3: Contact Drone Operator Directly

When to use: If you identify the operator; want resolution without authorities Process:

1. Safely identify the operator (note registration number, approach vehicle)
2. Request a conversation about the flight
3. Explain your concerns (privacy, safety, trespass)
4. Request the operator cease flights over your property
5. Document the conversation (notes, email confirmation)

Pros:

• ✅ Often fastest resolution
• ✅ Avoids formal enforcement
• ✅ Can establish ongoing communication

Cons:

• ❌ Operator may be uncooperative or hostile
• ❌ No enforcement power; depends on operator compliance
• ❌ Safety risk if confrontation occurs
• ❌ May escalate situation

Safety recommendation: Do NOT approach aircraft operator in person if you feel unsafe. Use third-party communication (letter, email) if possible.

Option 4: Civil Legal Action (Trespass/Privacy)

When to use: If police/CAA action unsuccessful; seeking damages Legal grounds:

• Trespass: Unauthorized entry onto airspace above property (within reasonable height)
• Privacy Act violation: Invasion of privacy through surveillance
• Negligence: Unsafe operation causing risk or damage

Process:

1. Consult private lawyer; gather evidence (video, photos, witness statements)
2. Send cease-and-desist letter to operator (establishes intent to enforce)
3. If operator continues, file civil lawsuit in District Court
4. Prove violation of privacy or trespass
5. Seek damages (compensation) and/or injunction (court order to stop)

Potential outcomes:

• Damages: Monetary compensation for privacy violation or property harm
• Injunction: Court order prohibiting operator from flying over property
• Attorney fees: Recovery of legal costs (if contract/agreement exists)

Challenges:

• Expensive (lawyer costs NZ$5,000-20,000+)
• Requires proof of harm (emotional distress, financial loss)
• Burden of identifying operator (if unknown)
• Civil court has lower burden of proof than criminal; but still requires substantial evidence

Example case: Owner flies drone daily over neighbor's property; neighbor proves Privacy Act violation; court orders operator to cease and awards NZ$5,000 damages :::

Legal Counter-Drone Defense Methods

Method 1: Deterrents & Warnings

Legal options to discourage drone operations:

Deterrent	Legality	Effectiveness
Warning signs	✅ Legal	Low (many ignore)
Verbal warnings	✅ Legal (from distance)	Medium (if operator present)
Notification letters	✅ Legal	Medium (formal notice)
Geofence walls	✅ Legal	Medium (educated operators respect)
Privacy barriers (nets, screens)	✅ Legal	High (physical barrier)

Best practice: Combination approach—warning signs + formal notification + physical barriers

Method 2: Physical Barriers

Legal:

• ✅ Tall trees/vegetation (blocks visual line of sight)
• ✅ Protective netting over sensitive areas
• ✅ Privacy screens or fencing

Not legal:

• ❌ Nets with intention to capture/damage drone
• ❌ Spikes or harmful devices
• ❌ Anything designed to damage aircraft

Example: Installing protective netting over swimming pool to prevent voyeurism is legal; same netting placed to entangle drones is illegal

Method 3: Electronic Detection

Legal electronic systems:

Technology	Legal Status	Purpose
RF (radio frequency) detection	✅ Legal	Detects drone signal transmission
Radar systems	✅ Legal (if not military)	Detects drone presence
Acoustic detection	✅ Legal	Detects drone sound/vibration
Visual detection	✅ Legal	Camera systems monitoring airspace

Not legal:

• ❌ RF jamming (interferes with radio signals)
• ❌ GPS spoofing (false location signals)
• ❌ Laser dazzling (aimed at aircraft)

Why jamming is illegal:

• Interferes with legitimate communications
• Violates Radio Spectrum Act
• May affect emergency services, aviation
• Criminal liability (up to NZ$10,000+ fine)

Method 4: Authorized Counter-Drone Operations

Only available to:

• Police (in authorized circumstances)
• Defense Force (security operations)
• Critical infrastructure operators (with regulatory approval)

Authorized methods:

• ✅ Manual capture (netting, catcher poles)
• ✅ Laser dazzling (authorized law enforcement only)
• ✅ Electronic countermeasures (under specific licensing)
• ✅ Firearms (extremely rare; only military/specialized law enforcement)

Not available to civilians/private property owners :::

ILLEGAL Counter-Drone Methods (Don't Do These)

Method: Shooting/Destroying the Drone

Legal status: ❌ Illegal (multiple violations) Violations:

• Weapons Act violation – Using firearm to destroy property
• Air Navigation Act violation – Damaging aircraft (even unmanned)
• Reckless endangerment – Projectiles falling from sky
• Assault (if drone operator nearby) – Threatening with force

Penalties:

• Criminal charges
• Prison (up to 3+ years for serious weapons offenses)
• Confiscation of firearms
• Permanent firearms license revocation

Why it's prosecuted heavily:

• Projectiles falling from sky endanger people below
• Uncontrolled response; escalates conflict
• No regulatory authorization
• Creates public safety hazard

Real case: Property owner in Australia shot down drone; faced criminal charges; convicted of weapons violation and fined AUD$3,000

Method: RF Jamming/GPS Spoofing

Legal status: ❌ Illegal (telecommunications violation) Violations:

• Radio Spectrum Act – Unauthorized transmission/interference
• Telecommunications violation – Jamming regulated frequencies
• Defense Act (if military frequencies) – Potential national security violation

Penalties:

• Criminal charges
• Fine: NZ$10,000-50,000+
• Confiscation of jamming equipment
• Potential imprisonment

Why it's prosecuted:

• Interferes with legitimate communications
• May affect emergency services (police, ambulance, fire)
• May affect aviation safety systems
• Broad societal harm

Example: Person attempts to jam drone over their property; RF jamming interferes with nearby police dispatch; prosecution for reckless endangerment

Method: Laser Dazzling/Pointing

Legal status: ❌ Illegal (if intentional) Violations:

• Air Navigation Act – Interfering with aircraft operations
• Crimes Act – Assault (depending on intent/outcome)
• Misuse of Laser Pointers Act – Unauthorized laser use

Penalties:

• Criminal charges
• Fine: NZ$5,000-15,000
• Imprisonment (if injury results)

Why it's serious:

• Pilots can be partially blinded
• Dangerous for manned aircraft (if in airspace)
• Creates safety hazard
• Hard to control effect

Note: Pointing a laser at a drone is treated similarly to pointing one at a manned aircraft—the regulations don't distinguish

Method: Netting/Capture with Intent to Damage

Legal status: ❌ Illegal (property destruction) Violations:

• Property Act – Destroying someone else's property
• Air Navigation Act – Interfering with aircraft
• Assault (depending on context) – If operator injured during capture

Penalties:

• Civil liability (must pay for drone damage)
• Criminal charges (property destruction)
• Potential assault charges

Why the distinction matters:

• ✅ Legal: Installing protective net over pool (protects your privacy)
• ❌ Illegal: Installing same net specifically to capture drones (destroys property)
• Intent matters; this is why authorities look at your stated purpose

Best Practices: Legal Drone Defense Strategy

Step 1: Document Everything

When unauthorized drone operations occur: `` DOCUMENTATION CHECKLIST: ☐ Date and time of incident ☐ Duration of flight ☐ Drone description (color, size, shape) ☐ Flight pattern/behavior (hovering, circling, near windows) ☐ Camera visible on aircraft (evidence of surveillance intent) ☐ Any registration numbers (if visible) ☐ Weather conditions (time of day, light, visibility) ☐ Video/photos (if safely possible; don't interfere with aircraft) ☐ Witness statements (neighbors who saw incident) ☐ Property damage (if any) `

Step 2: Identify the Operator (If Possible)

` IDENTIFICATION METHODS: ☐ Note registration number (CAA numbers on airframe) ☐ Follow aircraft to landing site (safely; do NOT confront) ☐ Determine who owns property where drone landed ☐ Check CAA online registry (if number visible) ☐ Consult with neighbors (may know operator) ☐ Contact local drone clubs (may recognize aircraft) `

Step 3: Escalate Through Proper Authorities

` AUTHORITY ESCALATION:

1. POLICE (if safety/harassment concern)

• File incident report
• Provide documentation
• Request investigation

1. CAA (if regulatory violation)

• File incident report online or by mail
• Describe violation (unlicensed operation, Part 101 violation, etc.)
• Provide operator ID if available
• Request enforcement action

1. PRIVACY COMMISSIONER (if privacy invasion)

• File complaint
• Detail privacy harm
• Request investigation and remediation
• May require operator to cease surveillance

`

Step 4: Implement Legal Deterrents

` DETERRENT OPTIONS: ☐ Install warning signs (discourages casual operators) ☐ Send formal notification letter to operator (if identified) ☐ Install geofence on your property (drone apps recognize zones) ☐ Install physical barriers (privacy screening, vegetation) ☐ Install detection system (cameras to document incidents) ☐ Establish neighborhood watch (coordinate with neighbors) `

Step 5: Consider Civil Action (If Necessary)

If police/CAA action unsuccessful and operator identified: ` CIVIL ACTION PROCESS:

1. Consult lawyer (initial consultation often free)
2. Gather evidence (documentation, video, witness statements)
3. Send cease-and-desist letter
4. If non-compliance, file civil suit
5. Seek damages and/or injunction
6. Attend court proceedings
7. If successful, enforce judgment

TIME FRAME: 6-12 months COST: NZ$5,000-20,000+ OUTCOME: Damages and/or court order to cease ``
