Spark Confirms 3G Network Shutdown by March 2026 – What This Means for NZ Businesses

Spark New Zealand has officially announced it will shut down its 3G network on 31 March 2026. While the date may seem distant, the implications for businesses that rely on 3G-connected devices are both significant and time-sensitive.

What’s happening?

Spark’s announcement is part of a global trend as telcos phase out older 3G networks to repurpose spectrum for faster, more efficient 4G and 5G technologies. In Australia, the 3G shutdown is already underway, and New Zealand is now following suit.

By March 2026, Spark’s 3G services will be fully retired. That means any device or system still relying on 3G connectivity will stop working unless upgraded.

What systems are affected?

The 3G shutdown will impact a wide range of business-critical systems across industries, including:

• EFTPOS terminals
• GPS vehicle tracking and telematics
• Farm and environmental sensors
• Security and alarm systems
• Industrial monitoring devices
• Vending, parking, and ticketing machines

If your business uses connected technology, it’s time to check whether 3G is still in the mix.

Lessons from Australia

When the 3G network shutdown began in Australia, many businesses left it too late. The result?

• Supply shortages on compatible 4G/5G hardware
• Field teams stretched thin trying to upgrade devices under pressure
• Service outages and operational downtime

Don’t let the same thing happen here. The smart move is to plan early and upgrade in stages—on your terms, not at the last minute.
