Pick TNZ if you're a business sending reminders, alerts or campaigns from a dashboard or your own systems. It covers SMS, email, voice and fax, its per-text rates are low, and it offers dedicated NZ short codes. Pick Agentline NZ if you want a personal AI assistant to have its own NZ 028 mobile number and email inbox that it can set up and use itself over MCP. TNZ doesn't offer an NZ mobile number. It sends to NZ mobiles from short codes, its dedicated short codes take about 4 weeks to set up, and its free trial doesn't include dedicated numbers.
