Slow progress in completing an inquiry is fuelling concern that the Commerce Commission is backing away from challenging Sky TV's hold on video content.
Critics say Sky TV is renegotiating its content contracts with ISPs to remove exclusivity and thereby avert potential calls for regulation.
The Commerce Commission inquiry into Sky TV was launched in May last year.
Sky TV spokeswoman Kirsty Way confirmed deals with ISPs were being renegotiated, but said this would have occurred without the inquiry.
Telecommunications Users Association of New Zealand chief executive Paul Brislen said there was growing concern the inquiry's findings would be "watered down".
