Halter: AI-Powered Virtual Fencing and Livestock Management for Dairy and Beef Farms
Halter is a precision livestock management system that combines solar-powered smart collars, on-farm communication towers, and a mobile app to enable virtual fencing, remote herd shifting, and real-time animal and pasture monitoring for dairy and beef operations. Headquartered in Auckland, New Zealand, Halter has spent close to a decade developing its proprietary hardware, software, and machine learning platform.
The system is designed to replace physical fencing with flexible virtual boundaries, allowing farmers to manage grazing rotations, move cattle, and track herd health from their phone. But beyond productivity, Halter also functions as resilience infrastructure: when wildfires destroy miles of fence, elk herds tear down wire overnight, or storms scatter cattle across rough terrain, virtual fencing allows operations to keep running without waiting for physical rebuilds.
AgentAya Verdict
Halter is one of the most advanced virtual fencing systems available. Its collar, tower, and app work as a single ecosystem that gives farmers a degree of grazing control and animal-level insight that conventional tools cannot match. At the core is the Cowgorithm®, a proprietary algorithm trained on billions of hours of behaviour data, which powers everything from directional guidance cues to health alerts and pasture cover estimation.
Farmers report saving over 20 hours per week on routine tasks like fencing and shifting. On the beef side, features such as preferential feeding and virtual laneway breaks enable grazing strategies that are simply not possible with physical infrastructure. The platform is English-only and does not publish standard pricing. a strong option for dairy and beef operations looking to cut labour, improve pasture utilisation, and gain real-time herd visibility. Halter’s confirmed operating markets are New Zealand, Australia, and the United States, with a “Rest of world” contact option on the website.

AgentAya Overall Score: 4/5 ⭐⭐⭐⭐
Ideal For
- Pasture-based dairy farms seeking to automate shifting, improve mating results, and harvest more pasture with data-driven allocation.
- Beef operations (from family ranches to large-scale enterprises) looking to enable rotational grazing on land where physical fencing is impractical, too expensive, or vulnerable to wildlife and weather damage.
- Farms dealing with labour shortages that need to reduce reliance on manual fencing, gathering, and herd monitoring.
- Operations in fire-prone, wildlife-corridor, or environmentally sensitive areas that benefit from adaptive, non-permanent boundaries.
Not Ideal For
- Small operations that cannot justify a per-collar subscription cost or do not need the full scope of the platform’s capabilities.
- Mixed-species farms: Halter only supports cattle (no sheep, goats, or horses).
- Operations that require multilingual interfaces or non-English support documentation.
- Farms that need extensive third-party software integrations or public API access.
Key Features
- Virtual fencing and shifting: create, move, and schedule virtual break fences from the app; shift entire mobs to new pasture with a single tap; back-fence automatically; plan breaks up to a week ahead.
- Pasture management (dairy): daily paddock cover and growth rate data; forecasted feed wedge for forward planning; per-mob feed demand and allocation comparison to avoid under- or over-feeding; kg DM per cow allocation for every break.
- Heat and health monitoring (dairy): automatic heat detection using individual cow behaviour patterns; daily heat list with submission and estimated in-calf rates; 24/7 behaviour monitoring for early health issue flagging; herd-level and individual cow data.
- Preferential feeding (beef): overlapping breaks allow different feed allocations to different animals within the same mob, without physical separation — useful for finishing stock, lighter cattle, or recently calved cows.
- Laneway breaks (beef): virtual corridors that can span multiple paddocks, enabling cattle movement toward yards or new pasture without physical gates or chasing.
- Creep grazing (beef): calves (uncollared) move freely through virtual boundaries while cows remain contained, giving calves first access to premium forage without additional infrastructure.
- Real-time animal tracking: GPS location for every collared animal at all times; storm tracking, gathering assistance, and loss prevention.
- Automatic pasture cover measurement: satellite and weather data integration for pasture estimation without manual assessment.
Beyond productivity: resilience on the ground
The daily efficiency gains are real, but farmers who have been using Halter for a while tend to point to something else: what happens when things go wrong. When wildfire tears through rangeland and takes miles of fence with it, virtual fencing lets ranchers keep managing cattle on that land without waiting months to rebuild. Some are also using it to graze invasive vegetation ahead of fire season, creating fuel breaks without mechanical treatment. In areas where elk or pronghorn regularly destroy wire overnight, there is simply nothing physical left to tear down — and no barbed wire left to injure migrating animals. When storms hit, GPS tracking confirms where every animal is without anyone driving out in bad weather. And on big operations where gathering used to mean weeks on horseback, knowing exactly where each animal is cuts that to days or hours. The common thread is adaptability: physical fencing locks you into decisions made years ago, while virtual fencing moves with the conditions on the ground.
AI Functions
Halter’s intelligence layer is built on the Cowgorithm®, a proprietary algorithm that automatically trains animals to respond to directional sound cues, enabling virtual fencing and remote shifting.
Each collar collects over 6,000 data points per minute, processed in real time via Halter’s cloud-based data platform.
The system draws on billions of hours of animal behaviour data collected across thousands of farms.
Machine learning models power virtual fencing guidance, animal health monitoring, heat detection, and satellite-based pasture cover estimation.
The AI adapts individually to each cow, calibrating cue responses based on that animal’s behaviour profile.
A team of over 100 engineers and designers develops and maintains the hardware, software, and AI components.
Integrations
Halter’s integration ecosystem is relatively closed compared to general-purpose SaaS platforms:
- Integrates with drafting gates and herd management systems: syncing heat and mating data.
- No public API catalogue: additional integrations are handled under project-based arrangements.
- The collar, tower, and app operate as a self-contained ecosystem: Halter’s towers provide connectivity independently of cellular coverage.
Data Security and Compliance
Halter’s privacy framework covers multiple jurisdictions:
- The Privacy Policy: addresses data collection, usage, storage, and disclosure for customers and users across all operating markets.
- Compliance references: include the New Zealand Privacy Act, Australian Privacy Principles, and the EU General Data Protection Regulation (GDPR).
- Animal and farm data shared with third parties: is disclosed only in aggregated, non-identifiable form unless required to provide the service.
- Third-party data processors: include AWS, Salesforce, Intercom, Vercel, and Meta, among others.

Language — Customer Support and Interface
The Halter app, Help Centre, website, legal documentation, learning hub, and all marketing materials are available exclusively in English.
App Store and Google Play listings do not indicate additional interface languages. There is no public mention of dedicated non-English support teams or translated knowledge bases.
AI Language — The Tool Itself
Halter’s AI operates on structured sensor and behavioural data (accelerometer readings, GPS coordinates, rumination patterns) rather than natural language input. The farmer-facing outputs — alerts, reports, pasture estimates, heat lists — are delivered in English through the app interface. There is no conversational AI assistant or natural language query feature documented.
Mobile Access
The Halter mobile app is the primary management interface, available on iOS and Android. Core functions include creating and moving virtual fences, scheduling and executing herd shifts, monitoring animal location and behaviour, reviewing pasture data, and receiving health and heat alerts. The app communicates with collars via the on-farm tower network, which operates independently of cellular coverage. A web app is also available for desktop access.
Support, Onboarding and Account Management
Halter provides a high-touch onboarding and support model. Each customer receives a customised training plan covering collar fitting, animal training (7 days for dairy, 10 days for beef), and app setup. A dedicated regional Territory Manager is assigned for ongoing guidance and check-ins.
The platform includes a 24/7 New Zealand-based customer support team accessible via the app, along with a Help Centre and learning hub with self-service documentation, troubleshooting guides, and educational resources.
The subscription includes a hardware warranty: collars and towers damaged by weather or natural animal behaviour are replaced at no additional cost. Halter also maintains a dedicated R&D budget with ongoing feature releases informed by farmer feedback.
Ease of Use / UX
The Halter app is designed around farmer workflows: creating breaks, shifting mobs, and reviewing data are streamlined into a few taps. The interface includes a digital twin of the farm with live animal locations, pasture data, and feed availability by paddock.
The initial setup requires hardware installation (towers) and a 7–10 day animal training period before the system is fully operational. Advanced features such as preferential feeding, laneway breaks, and feed wedge planning have a moderate learning curve but are supported by the onboarding process and Territory Manager guidance.
Farmers consistently describe the shift from physical to virtual fencing as transformative once the training period is complete, with daily management tasks becoming significantly faster and more flexible.
Pricing and Plans
Halter does not publish standard pricing. The service operates on a subscription model that includes hardware (collars and towers), software access, 24/7 support, and hardware replacement.
Pricing is determined through a personalised consultation based on herd size, farm area, and operational needs. Prospective customers can request a demo via the Halter website or by contacting the sales team.
Recommendation: calculate expected ROI based on labour savings, pasture utilisation gains, and production improvements. Request a detailed SLA and scope of support as part of the contract negotiation.
Case Study
A 600-cow dairy farm on rolling hill country in the Waikato, New Zealand, adopted Halter to cut the time spent on daily shifting and improve pasture use across paddocks that were hard to fence consistently with physical infrastructure.
Once the cows completed their training period, the manager started setting the next day’s breaks from the app each evening. Mobs moved on schedule without anyone on a quad bike, freeing up several hours each morning. Back-fencing kept cows off grazed areas, and the daily paddock cover data helped the team balance allocation between easy flats and steeper hillside paddocks that had previously been under-grazed.
Halter’s heat detection also picked up cycling cows the team had been missing during busy calving weeks, which lifted submission rates heading into mating. By the end of the first full season, the farm reported better pasture harvested per hectare, less daily labour on fencing and shifting, and stronger mating results — without changing genetics, supplements, or any other part of the system.
