Some believe Adams' endorsement signals an eventual clash with Telecommunications Commissioner Ross Patterson.
Adams mirrored Fellet's view that competition should be resolved by "the market" and negotiations among businesses.
But internet service providers such as TelstraClear have previously raised alarm bells about Sky's dominance including restrictive contractual terms that limit acquiring content outside deals with Sky.
Internationally, video on demand has played a major role in the uptake of UFB but Sky has challenged the inclusion of content on the periphery of a Commerce Commission study.
Adams said yesterday she would be closely monitoring issues that might affect the uptake or effective implementation of UFB and expected the industry to show leadership
"Where that does not occur I am more than prepared to step in. But I'm ... cautious about reaching for regulation as a solution at this stage when it is too early in my view to anticipate how the competitive content market will look."
MediaWorks managing director Sussan Turner told the conference New Zealand needed a regulated wholesale market for content. The aggregation of screening rights by rivals Television New Zealand and Sky, which recently entered into a joint venture called Igloo, was stifling opportunities for rival broadcasters.
"Separate regulation of broadcasters and telcos is antiquated and limits growth, innovation and competition," Turner said.
"It's MediaWorks' contention that telco companies and free-to-air broadcasters won't have much without a wholesale market for content."
