Nationwide reach. Locally owned. Based in Christchurch.
PTT NZ Limited is a Christchurch based specialist in mission-critical Push-to-Talk over Cellular, on-body cameras, IoT hardware and multi-network connectivity nationwide. We exist because critical comms shouldn't be tied to a single carrier — especially in a country as varied as Aotearoa and with disasters becoming more regular. Services can not be fully reliant on direct to cell satellite as this itself is dependent on ground stations and clear sight to the sky.
A platform built for how Kiwi teams really work.
From the West Coast to the Coromandel — and beyond NZ shores — single-carrier coverage has limits. PTT NZ has taken on the challenge to fix that with a multi-network SIM/eSIM platform that connects natively to Spark NZ, 2degrees and One NZ, with genuine native local access across Australia's major networks — not a roaming bolt-on — plus 190+ countries globally via international roaming partners. Paired with hardware tough enough for the field.
Today we support utilities, construction, transport, security and primary industries with PoC radios, evidence-grade body cameras, IoT terminals and broadband redundancy — all backed by a Christchurch-based team that picks up the phone.
Why we're not a roaming SIM.
Local network agreements and native Local Breakouts in Auckland and Sydney set PTT NZ apart from providers that simply resell overseas roaming.
In New Zealand, our SIMs connect natively to Spark NZ, 2degrees and One NZ. In Australia, we use the Telstra Direct (Retail) network — not Wholesale — alongside Optus and Vodafone, with strongest signal wins and continuous real data-access monitoring, not a limited wholesale roaming tier.
Data from a New Zealand SIM exits locally in Auckland; data from an Australian SIM exits locally in Sydney. Eliminating the overseas backhaul most global providers rely on keeps latency down to under 40ms — critical for real-time Push-to-Talk, live video, body cams and telemetry.
Many international roaming and travel SIMs get disconnected or throttled after roughly 60–90 days on a foreign network under standard fair-use policies. Because our SIMs run on native, locally-agreed networks rather than a roaming profile, PTT NZ deployments aren't exposed to that risk.
Our SIMs support LTE-M (Cat-M1) low-power wide-area connectivity with automatic multi-network failover built into the hardware layer — devices switch networks without draining the battery, ideal for sensors, meters and remote telemetry.
Local breakouts mean sensitive corporate, enterprise and government data stays within domestic borders in both New Zealand and Australia — supporting regulatory compliance frameworks in each country.
PTT NZ SIMs run on an independent core network profile — not a standard consumer multi-IMSI profile that forces a mechanical reset every time you switch towers. Selection is fully non-steered: your device locks onto whichever network has the mathematically strongest signal, organically, with no artificial carrier throttling or intentional prioritisation.
The same native, non-steered architecture is available to government agencies either as a complete primary network or as a complementary resilience layer alongside an existing one — with domestic NZ-hosted management and zero-firmware provisioning.
