From the end of 2025, New Zealand’s 3G mobile networks will be permanently shut down. While consumers may only need to check their phones, for fleet operators the impact goes much deeper. Any device that relies on 3G — from GPS units to telematics devices, electronic road user charging (eRUC) systems, and safety alarms — will stop working overnight.
For fleets, this is not just a connectivity issue. It’s an operational risk that can disrupt compliance, safety, and business continuity.
Lessons from Australia’s 3G Shutdown
Webfleet, which supported fleets during the Australian 3G transition, has a clear message for New Zealand operators: don’t wait until the deadline.
When Australia switched off 3G, fleets that delayed upgrades faced:
- Installer shortages and skyrocketing costs: Auto electricians and installers became overwhelmed, with demand driving up prices. Many fleets paid many times the usual rate just to get devices fitted
- Complex installations: Upgrading wasn’t always a simple swap. Dashcams, lone worker safety systems, and other solutions hardwired into 3G telematics units often needed reconfiguration, extending downtime
- Loss of critical functions: Once 3G was shut down, fleets lost GPS visibility, driver safety monitoring, routing, job dispatch, and pre-start check integration. Heavy vehicle operators even found they were facing fines and could no longer book permits because their telematics devices were non-compliant. Other business units also saw disruption as data, such as driver hours for payroll, was no longer available.
The result? Operations ground to a halt for those who didn’t act early.
Why the Risk is Greater in New Zealand
In New Zealand, the 3G shutdown has an added complication: the electronic Road User Charges (eRUC) system. Many fleets rely on digital RUC reporting linked to telematics devices. If those devices can’t connect after the 3G switch-off, you’ll be left working on paper — reducing accuracy, losing money, and risking compliance.
For fleets doing a mix of on-road and off-road work, this accuracy is essential. Without it, fuel rebates and compliance with RUC rules are compromised.
What Fleet Managers Need to Do Now
- Audit your assets
- Identify which vehicles and devices are still 3G-dependent (GPS, telematics, tracking, RUC systems, lone worker devices, safety alarms).
- Plan the rollout
- Don’t leave all upgrades to the Christmas break. Installers will be scarce, and many will also be on leave.
- Instead, phase upgrades in smaller batches across your fleet to spread costs and reduce downtime.
- Engage suppliers early
- Most telematics providers, including Webfleet, offer flexible options such as subscription-only models or delayed billing to ease the CapEx burden. That means fleets don’t need to absorb tens of thousands of dollars in upfront hardware costs.
- Communicate with stakeholders
- Ensure your operations, compliance, and finance teams all understand the risks and timelines. The shutdown will affect reporting across your business – RUC reporting, safety systems, and vehicle tracking are all affected.
- Use the transition to upgrade capability
- Moving to 4G/5G is not just about replacing old hardware. It’s an opportunity to review how telematics supports safety, compliance, and efficiency — from advanced routing to driver monitoring.
The Cost of Waiting
Australia proved that waiting until the last minute is the worst approach. Fleets that delayed found themselves facing higher costs, longer downtime, and in some cases, vehicles taken off the road entirely
New Zealand fleets have the advantage of foresight. The date is set, the risks are known, and suppliers are ready to help. The key is to act now.
The 3G shutdown is not just a telco upgrade. For fleets, it’s a critical transition point that will impact compliance, efficiency, and safety.
Fleet managers who start early, plan the rollout, and work closely with suppliers will avoid disruption — and turn a looming risk into an opportunity to strengthen their telematics capability.
