Mobile Systems Limited supplies rugged two-way radio systems for construction sites across New Zealand, built to handle dust, drops and constant background noise. Our core site range covers the Hytera HP702 and HP782 digital portables, paired with Sensear SM1R and SM1P2 noise-cancelling headsets so your crew can still hear instructions over machinery. For multi-level builds and basement car parks where mobile signal drops out, we fit Cel-Fi GO G41 cellular boosters and Hytera repeater base stations. We also supply VMS trailers for traffic management and can integrate lone worker monitoring. As a brand-independent advisor, we recommend the setup that suits your site, not the easiest sale.
A radio that can't cut through the noise is just weight on a belt.
Two-way radios built for site conditions
Hytera HP702 and HP782 digital portables
Our most-supplied handhelds for construction crews. Both are DMR digital radios built to survive drops, dust and vibration, with clear audio over reversing beepers, saws and generators. We programme every unit to your channel plan before it leaves our workshop. Browse the full Hytera range.
Motorola R5 VHF portable
A solid alternative where a VHF site licence already exists or open-ground coverage matters more than in-building penetration, such as a large civil or roading job. The Motorola R5 is configured and supplied the same way as our Hytera range.
Sensear noise-cancelling headsets
The SM1R and SM1P2 suppress harmful site noise while letting speech and alarms through, so a worker can hold a radio call and still hear a warning shout without pulling off hearing protection. See the full headset range.
Solving dead zones on multi-level and basement builds
Cel-Fi GO G41 Building Pack
Concrete floors and structural steel routinely kill mobile signal on multi-storey and basement levels. The Cel-Fi GO G41 boosts existing cellular signal throughout the site, keeping phones and PoC devices usable floor by floor. See the full Cellular Signal Boosters lineup.
Hytera repeater and base station
For sites relying on licensed two-way radio rather than cellular, a base station such as the Hytera HR-1062E extends portable coverage across a larger footprint or between buildings, keeping crews on different levels on the same channel.
Traffic management and site safety
VMS trailer hire
Solar-powered variable message sign trailers for real-time traffic and pedestrian messaging around an active site, available to hire for the length of a project.
Lone worker and site safety monitoring
Where staff work alone or after hours, we integrate GPS check-ins and man-down alerts alongside your radio fleet through our Worker Safety and Asset Management service, so a missed check-in is never treated as routine.
Why order your site communication system through MSL
Built for the site. Every radio, headset and booster is matched to your actual site conditions, terrain and building layout, not a one-size-fits-all package.
Programmed before it reaches site. Radios arrive pre-configured to your channel plan and, where relevant, RSM-licensed frequency, so your crew is talking from day one.
On-site support, wherever you are based. We install directly across the Bay of Plenty, Coromandel, Rotorua, TaupΕ and Waikato, and coordinate with trusted installers nationwide or supply fully configured equipment for your own team.
Brand-independent advice. We stock and support multiple radio, booster and headset brands. Our recommendation is based on what suits your site, not what is easiest for us to sell.
Construction site communication FAQs
What's the best two-way radio for a construction site in NZ?
For most sites, a DMR digital portable such as the Hytera HP702 or HP782 gives the best balance of durability, clear audio and channel capacity. Sites needing VHF for licensing or open-ground reasons often use the Motorola R5 instead.
How do we fix dead spots on a multi-level or basement build?
A Cel-Fi GO G41 cellular booster or a Hytera repeater base station, depending on whether your team relies on mobile or licensed radio, typically closes coverage gaps between floors and basement levels.
Can we get hearing protection and a radio in one headset?
Yes. Sensear's SM1R and SM1P2 headsets suppress harmful noise while enhancing speech and alarms, so your crew stay protected and connected without removing hearing protection to talk.
Do our site radios need an RSM licence?
Most commercial private-channel use does. We handle the RSM application and programming as part of supply, so this is not something you need to sort out separately.
Can you monitor lone workers on our site?
Yes. We can add GPS check-ins and man-down alerts for staff working alone or after hours through our Worker Safety and Asset Management service, integrated alongside your existing radio fleet.
Kitting out a site?
Tell us about your build, and we will spec radios, headsets and coverage to match. Running a factory floor instead? See our Manufacturing Facility Radio Communication guide.
