Earlier this month, Quickflix complained about the ISP contracts in a submission to the regulator's investigation into demand-side drivers for broadband uptake, saying they would stifle uptake of ultra-fast broadband, and yesterday welcomed the probe.
Buckley said it was "inappropriate" for Sky to cut deals with ISPs that impact on third-parties and constrain rivals' ability to enter into separate contracts.
News Corp-controlled Sky's dominance in the market has been a bone of contention for its rivals, and a joint venture with state broadcaster Television New Zealand to set up a budget pay-TV option consisting of various Sky channels and TVNZ's free-to-air content annoyed the media companies' rivals.
The regulator yesterday approved the joint venture, saying it would not erode competition.
Quickflix joins broadcaster MediaWorks, whose stable of TV and radio stations include TV3, Four, The Rock and RadioLive, in calling for an independent regulator of the two increasingly related sectors to ensure a level playing field.
The Government has so far resisted that step, with new IT Minister Amy Adams earlier this year saying it was too early to regulate a structure that is still in a state of flux, and that the market might solve any problems on its own.
Adams acknowledged the regulator's probe yesterday, saying it was "always my view that was within their jurisdiction so good to see will be looked at", in a Twitter update.
Quickflix's Buckley said it would be "sensible" to introduce an industry-specific regulator before the sector gets too far ahead of itself, and that such a move would probably attract a groundswell of support.
"I'm certainly under the impression the majority of people in our industries would favour some sort of independent regulator. Sky wouldn't," he said. "I just don't think this is a political thing. This is just saying what's sensible given where we are."
Quickflix's shares rose 4.6 per cent to 11.5 Australian cents on the ASX today.
