Your Duty of Care Under the HSWA
The Health and Safety at Work Act 2015 requires every business to take all reasonably practicable steps to protect workers from harm, and that duty doesn't stop at the office door. For anyone working remotely, alone, or somewhere mobile coverage is patchy, "reliable communication" isn't a nice-to-have, it's part of the legal baseline.
Relying on personal mobile phones alone creates a real gap here. NZ's rugged terrain, from forestry blocks to backcountry farms, means cellular coverage is often patchy or absent exactly where the risk is highest. A missed call during an emergency isn't just bad luck, it's a failure of the communication system a business was supposed to have in place.
A professional two-way radio system, run on its own dedicated frequency independent of the public cellular network, is one of the clearest ways to demonstrate that due diligence. It's a tangible, auditable step showing you identified communication as a risk and did something about it.
Safety Features That Do the Heavy Lifting
Modern digital radios go well beyond simple push-to-talk. The features below are what actually turn a communication device into a safety tool, and they're the difference between a basic radio and a genuine compliance asset.
| Feature | What It Does | Why It Matters |
|---|---|---|
| Emergency Button | One press sends an instant, network-wide distress signal, overriding other traffic | Guarantees a call for help gets through even in a chaotic moment |
| Lone Worker Monitoring | Prompts a periodic check-in; triggers an alert if the worker doesn't respond | Catches a problem even when the worker can't call for help themselves |
| Man Down Alert | An internal sensor detects a fall or prolonged horizontal position | Flags an incident automatically, without requiring any action from the worker |
| GPS Tracking | Transmits real-time location to a supervisor or dispatch | Cuts response time by removing the guesswork of where to send help |
None of these features are universal though. They're generally found on digital radios rather than basic analogue sets, so if lone worker compliance genuinely matters for your business, it's worth confirming the specific model you're buying actually includes them rather than assuming.
Choosing the Right Frequency and Getting Licensed
UHF and VHF aren't a "which is better" choice, they're different tools for different terrain. UHF's shorter wavelength punches through concrete, steel and dense bush, making it the standard for construction sites, built-up areas and forestry blocks. VHF's longer wavelength travels further across open country with fewer obstacles, which is why it's the standard for large farms, marine environments and open rural land.
Commercial radio use in NZ generally requires a licence from Radio Spectrum Management (RSM), giving your business a private, interference-free frequency rather than sharing a crowded public channel. Current RSM fees, effective 1 July 2026, are:
| Licence Type | Covers | Annual Fee |
|---|---|---|
| Standard individual licence | A single frequency or simplex use | $190 |
| Land mobile, up to 5 repeaters | Up to five repeater locations on a common frequency | $800 |
| Land mobile, unlimited | Unlimited repeater locations nationwide | $1,800 |
A reputable supplier should handle this licensing process for you as part of the sale, not leave you to navigate it alone. See our channel licensing and programming service for how this works in practice.
How NZ Industries Actually Use This
Forestry and Agriculture
Long-range VHF is the standard across large, open properties where the nearest cellular tower might be an hour's drive away. A lone worker mustering stock or felling timber stays in contact with base, able to report a hazard or call for help without relying on a phone signal that was never there to begin with.
Construction Sites
UHF's ability to penetrate concrete and steel makes it the standard on busy, multi-level sites. A crane operator needs a constant, clear line to the dogman on the ground, and that link has to survive the noise and structural interference a phone call simply can't handle.
Marine Environments
Waterproof, IP67-rated VHF marine radios are the baseline offshore, built to survive saltwater and submersion while providing vessel-to-vessel communication, weather alerts, and a direct line to Coastguard when it matters most.
Emergency Services
New Zealand's Public Safety Network, built on P25 Phase 2 technology, is what allows Police, Fire and Emergency NZ, and ambulance services to share a common, interoperable radio network, replacing the previous NGCC-managed arrangements now delivered under SafetyNet Critical Communications since July 2026. It's a clear demonstration of how a shared standard underpins safety at a national scale, even if most commercial users won't need P25 specifically.
Getting It Right with Mobile Systems
Meeting your health and safety obligations isn't about buying the most expensive radio on the shelf. It's about matching the right frequency, features and licensing to how your team actually works, then making sure everyone knows how to use the safety features that matter.
Site Assessment
We identify your actual coverage needs and risk zones before recommending hardware.
Lone Worker Integration
Man Down, GPS and emergency alerts configured through our worker safety and asset management service.
Licensing Handled
We manage the RSM licensing process so it's one less thing on your plate.
Training and Support
The best safety feature is useless if your team doesn't know how to use it under pressure.
