Uptake had been encouraging during the recent switch-off for analogue services in Christchurch.
Igloo general manager Chaz Savage exited this year, three months after the launch and a new general manager, David Joyce, was appointed.
Sky TV has more to gain than TVNZ from the joint venture. At $25 a month - about 60 per cent of a basic Sky subscription - Igloo aims to draw customers who do not want to pay for a full Sky subscription. Igloo is also expected to diminish potential market for any new pay TV operators.
TVNZ chief executive Kevin Kenrick declined to comment on uptake and said Igloo was aimed at an audience which wanted a few pay TV channels, but was not interested in sports.
A TVNZ source said it would be watching closely to see the performance of Igloo after the failure of last venture into pay television technology - Tivo. The 50 per cent stake in the company led to a $14.8 million write off in the TVNZ accounts for the year to December 31, 2010.
