Sky shares jumped after the morning announcement and finished up 33c at $6.08.
"Essentially the result is a good one because they have lowered their programme costs, which is a key element," said Greg Fraser, of Mint Asset Management.
Fraser said Telecom had made it clear that it did not intend to compete with Sky TV.
"They [Telecom] are certainly not interested in chasing the key sporting content, which is the real basis on which Sky TV's business is built," he said.
As it stands, Sky has exclusive New Zealand rights to the Super 15 rugby competition and to All Black test matches.
"What they [Telecom] are looking at is a more expanded offering for the broadband and mobile phone customers. It's something to make their customers more sticky to Telecom, but not necessarily with internet TV as a core product," Fraser said.
The equivalent in Australia is Fetch TV, which some local telcos carry but which does not feature sport.
My Sky subscribers now represent 56.7 per cent of Sky's subscriber base compared with 50.1 per cent in the previous comparable period.
Sky's gross churn - the percentage of subscribers that discontinue their subscription over the period - was 13.3 per cent, down from 14.6 per cent in the previous period.
Programming costs - made up of the cost of buying programme rights plus programme operating costs - fell by $13.5 million.
Telecom, which plans to change its name to Spark, said last week that it intended to enter the internet television market.
