Under Part 3 of the Telecommunications Act 2001, Telecommunications Service Obligations (TSO) are entered into in order
to facilitate the supply of certain telecommunications services that may not otherwise be supplied on a commercial
basis, or at a price that is considered by the Minister of Communications to be affordable to the affected end-users.
There are currently two TSO instruments:
TSO Deed for Local Residential Telephone Service between the Crown and Telecom; and
TSO Deed for Telecommunications Relay Services (TRS) for the hearing impaired between the Crown and Sprint.
The TSO instruments costs once determined are apportioned among liable persons. Prior to the revision of the
Telecommunications Act this cost apportionment was part of the TSO determinations. Now, under the revised act, the
apportionment is provided in a separate cost allocation determination.
The Commission administers the TSO deeds by:
monitoring compliance of the service providers;
determining the cost faced by the service providers, unless the amount is specified in the deed;
determining the liable persons; and
the apportionment of this cost among the liable persons.
The ‘liable persons’ are Telecom and the companies operating public switched telephone networks (PSTN) that are
interconnected with Telecom’s PSTN.
