No overall score

One of 56 brands reviewed. Not in the priced comparison: prices on a published rate whose stated currency contradicts itself on the same page, not monthly volume.

Right for you if
  • A dedicated Australian site, phone number and separate contacts, not only a support line inside a New Zealand company
  • A published SMS rate exists, alongside fax, voice and email pricing on the same account
  • No minimum contract term, and multi-currency billing including AUD, NZD, USD and EUR
  • API, MMS, email-to-SMS, two-way and SMPP sending, with Telstra, Optus and Vodafone named as destinations
Look elsewhere if
  • Its pricing page footnote says New Zealand dollars while its FAQ on the same page says AUD, and other pages list 10c per SMS part against the pricing page's 6c
  • Support hours are stated in New Zealand time even on the Australian facing contact page
  • The published plan carries a $20 a month fee
  • No rate is carried in the tables above, since the currency and the rate both conflict across TNZ's own Australian pages

Where TNZ Group stands

TNZ Group is a bulk messaging platform headquartered in Auckland, New Zealand, tracing its history to a 1991 founding through Faxware International and a 2001 merger that formed the group as it trades today. It maintains a dedicated Australian site, tnz.com.au, with its own Australian phone number and separate support, sales, accounts and faults contacts, a real local presence rather than a support line alone. Its pricing page lists SMS to an Australian mobile at 6c per SMS part on a $20 a month plan, footnoted as New Zealand dollars excluding GST, while the FAQ on the same page says the listed prices are AUD, and three other tnz.com.au pages state AUD and list 10c per SMS part. This review states the conflict rather than resolving it.

How TNZ Group prices

TNZ Group publishes no per-message rate that maps onto a monthly sending volume, so this page prints none. It prices on a published rate whose stated currency contradicts itself on the same page.

TNZ's pricing page lists sending an SMS to an Australian mobile at 6c per SMS part on its one published plan at $20.00 a month, but the same page's footnote states its prices are in New Zealand dollars excluding GST, while the FAQ on that page says the listed prices are AUD and that NZD, USD and EUR are supported. Other tnz.com.au pages state AUD and list 10c per SMS part on three product pages. Both the currency and the rate conflict across TNZ's own Australian pages, so the contradiction is stated here rather than resolved on the provider's behalf and no rate is carried in the tables above.

TNZ Group pricing

TNZ Group prices on a published rate whose stated currency contradicts itself on the same page. Its pricing page lists an SMS to an Australian mobile at a per SMS part rate on its one published plan, which carries a monthly fee. The footnote on that page states the prices are in New Zealand dollars excluding GST. The FAQ on the same page says the listed prices are AUD, and that NZD, USD and EUR are supported.

Three other tnz.com.au product pages state AUD and list a different per SMS part rate from the pricing page's. Both the currency and the rate conflict across TNZ's own Australian pages. This review states the conflict rather than resolving it, and no rate is carried in the rate table above.

The plan is not your only cost. A dedicated virtual Australian mobile number carries $50 setup plus $40 a month for a dedicated Australian virtual mobile number (long code), month to month, stated in Australian dollars excluding GST on the virtual-number page; the same page prices messages from it at 10c per SMS part, with month-by-month terms and cancellation at any time, per the same page. There is no minimum contract term, and billing supports AUD, NZD, USD and EUR.

A no-obligation free trial account is available on request. The pricing FAQ says the Prepay features can be trialled, though no credit amount or trial length is published. What TNZ Group publishes about sending, not pricing, fills the next section.

TNZ Group features for Australian senders

TNZ Group publishes a REST API with JSON and XML support. Email to SMS covers sending and receiving SMS messages via email. Two-way SMS is on by default, so a recipient can reply to a message. An SMPP gateway supports delivery to New Zealand, Australia and other countries globally.

MMS support extends to Australian mobiles. A dedicated virtual Australian mobile number is offered for sending, and a shared number supports two-way messaging over email, web or APIs. An alphanumeric sender ID lets you set your "From" name to a custom string of text. TNZ Group publishes nothing either way about RCS to Australian mobiles.

Its published routes name Telstra, Optus and Vodafone as destinations, plus New Zealand, the United Kingdom and other worldwide mobile networks. The page does not say whether those connections are direct. How it sits with the ACMA register comes next.

TNZ Group sender ID and the ACMA register

ACMA's approved list for the SMS Sender ID Register lists TNZ Group under its own name as a partner of a certified telco, with the entry TELECOMMUNICATIONS AUST PTY LIMITED. That listing means you can register a sender ID for Australian sending through TNZ Group as an approved partner.

Your sender ID choice matters here. An alphanumeric sender ID sets your "From" name to a custom string of text, which suits brand recognition on one-way sends. A dedicated or shared number is the path for two-way conversations. Support and reputation follow.

TNZ Group support and reputation

Support, sales, accounts and faults are each handled by separate email addresses. Stated support hours are Monday to Friday business hours, New Zealand Standard Time, and they appear that way even on the Australian facing contact page. An Australian phone number and separate Australian contacts back the local presence.

TNZ Group traces its history to a 1991 founding through Faxware International and a later merger that formed the group as it trades today. No uptime claim or public review rating is carried in the quick-facts list above, since none was published. Who it suits follows.

Who TNZ Group suits

TNZ Group suits a business that wants one account for SMS, fax, voice and email, with API, MMS, email-to-SMS, two-way and SMPP sending, and no minimum contract term. The dedicated Australian site, phone number and separate contacts give you a real local presence rather than a support line inside a New Zealand company.

Look elsewhere when you need a firm per-message cost in Australian dollars. The published rate and currency conflict across TNZ's own Australian pages, so a business that must quote its message spend precisely, or wants support hours in Australian time, cannot rely on what is published today.

How much is TNZ Group?

TNZ Group publishes no per-message price that maps onto a monthly volume; it prices on a published rate whose stated currency contradicts itself on the same page. Ask for a written quote before you compare it on cost.

Who owns TNZ Group?

TNZ Group names no parent company on its own pages. Its head office is in Auckland, New Zealand, and it was founded in 1991.
