The Telecommunications Development Levy (TDL) is levy on telecommunications companies in New Zealand, which funds various infrastructure and services which otherwise would not be available at an affordable price. It is payable by telecommunications firms with an operating revenue of over $10 million, in proportion to their qualified revenue. The government has currently set the TDL at $50 million annually to fund improvements to communications infrastructure such as the Rural Broadband Initiative. The levy adds about $1 per month to a typical broadband or mobile phone bill.
