Local Voice & SMS Connectivity for AI Agents in New Zealand and Australia

The rise of agentic AI has transformed customer engagement. Platforms like Vapi and Retell AI are revolutionizing voice, while tools like n8n and GoHighLevel are automating text conversations at scale. But even the smartest AI needs a reliable reliable way to speak to the outside world.

For AI Agent companies targeting New Zealand and Australia, the challenge isn't the AI, it’s the telephony. Global CPaaS providers often struggle with the nuances of local carrier restrictions, particularly in New Zealand. That’s where TNZ comes in. TNZ offers Voice and SMS connectivity to connect your agent to local customers.

One Platform for Voice & Text

To deliver a truly seamless experience, your AI agent needs to operate where your customers are. Relying on generic international routes can lead to latency in voice calls (killing the conversational flow) or undelivered SMS due to carrier filtering.

TNZ provides a unified gateway that handles both Voice (SIP) and Text (SMS and WhatsApp) through a single relationship. We handle the carrier complexity so you can focus on the conversation design.

Deep Dive: Capabilities by Country

New Zealand and Australia operate differently, and a "one-size-fits-all" approach will fail. Here is how we empower your agents in each market.

1. New Zealand Connectivity 🇳🇿

New Zealand is a highly regulated mobile environment.

• SMS Agents: You cannot use standard long-code mobile numbers for Application-to-Person (A2P) messaging. To enable two-way chat for your AI, TNZ provides Short Codes (e.g. 3456). This ensures high deliverability and compliance with local mobile network codes.

• Voice Agents: We provide local landline numbers (e.g. 09 500 5000) with full SIP connectivity. Your AI can make outbound calls via SIP or receive inbound traffic directly. We also support simple call diversion, routing inbound calls to a mobile or voicemail.

2. Australian Connectivity 🇦🇺

Australia offers more flexibility but requires strict identity verification.

• SMS Agents: We host Virtual Mobile Numbers (e.g. +61 401 020 304). You can use these "long codes" for two-way conversations.

• Voice Agents: Similar to NZ, we offer local landline numbers (e.g. 02 5000 5000) ready for SIP trunking and inbound call diversion.
