Sietec Wholesale Networks

Giving your business direct access to wholesale services and rates across lines, calling and data via our partnerships with every carrier in NZ – and that’s just the beginning.

Optimize Every Dollar

Communication spend remains one of the largest operating costs for many businesses. It’s often a complex beast, with more than one provider involved, and a general lack of visibility about where costs are really being spent and why.


Business Phone Lines & Data

Sietec can provide your business with wholesale access to high quality VoIP, analogue lines, ISDN as well as premium data connections such as Fibre and Ultra Fast Broadband, in turn providing entry to the vast range of features available on Cloud and Unified Communication platforms.

Calling & Tolls

Wholesale rates for calling and tolls is just the starting point. Get completely customized calling plans based on your actual calling history and businesses requirements. Remove those pain points and improve your bottom line.
