The code was devised following a request from Communications and Information Technology Minister Amy Adams, who welcomed the announcement this morning.
"As the Ultra-Fast Broadband network is rolled out around the country, consumers will need a clear foundation on which to consider and compare broadband offerings," Adams said.
"It is important that consumers are provided with accurate information about competing product offerings and are able to make informed choices. The introduction of a code is an important step towards improving transparency for broadband products in New Zealand," she said.
The TCF said today that a new testing method is also being developed to help consumers gauge the performance they are likely to receive from different broadband services.
Telecommunciations Users Association chief executive Paul Brislen said it was good to see consumers would get some clarity in broadband products are presented.
Brislen said previously "confusion had been used as a marketing tool" by some telcos and the code would go a way to stopping that.
The code would become increasingly important as ultra-fast broadband gets more popular, he said.
