Local and Mobile Number Portability are regulated multi-network services under the Telecommunications Act 2001. The Commerce Commission is responsible for determining the terms relating to local and mobile number portability. Those terms are set out in the Commission’s Local and Mobile Number Portability (LMNP) Determination.
Once a new party has been issued a number block by the Number Administration Deed (NAD) and operates a PSTN they are considered to be a party to the LMNP Determination and are liable for costs under that Determination.
The TCF assists with facilitating access to the Industry Portability Management System (IPMS), working with industry to ensure that service levels for LMNP are adhered to. The TCF is also responsible for the managing the cost allocation process for LMNP.
