Sky Television's shares have slumped this morning on news that the Commerce Commission is delaying its decision on whether to approve the company's tie-up with Vodafone New Zealand.
The regulator is concerned the merged entity would use its muscle to squeeze out smaller rivals.
Sky shares were down 4.17 per cent this morning to $4.60 after the announcement.
The commission is in talks with the companies to extend the application timeframe to give them the opportunity to submit on its initial view, it said in a statement. At this stage, the commission isn't satisfied the deal wouldn't limit competition, saying while consumers may benefit from cheap services at first, other broadband and mobile providers could lose the ability to build scale in their businesses and become weaker rivals.
"Over time, this could reduce competition in these markets and potentially enable the merged entity to raise prices or lower the quality of service beyond what it would be able to without the merger occurring," the commission said.
