Discount pay television service Igloo has been delayed again, after a series of hold-ups due to technical issues.



Chief executive Chaz Savage said it was still dealing with those technical issues and isn't setting a new target launch date.



Igloo had aimed to launch the product at the end of this month. It originally meant to launch in late June, then postponed until July and then early August.



Savage said the situation was frustrating, but it didn't want to put out the product until it was 100 percent confident with it.



"There is no doubt that it's a complex product. We realise the original June timeframe was aggressive and unrealistic."



Igloo is 51 per cent owned by Sky Television, with Television New Zealand holding the remainder of the joint venture.



Despite the delays, its relationship with TVNZ and Sky was great, he said.



"They share our view and sentiment that we don't put it out until we've ironed out all the creases with it."



It was trialling 200 set-top boxes and so far the feedback from customers was positive, he said.



Its $200 set-top boxes will be capable of receiving all free-to-air channels, 11 pay-television channels for a monthly fee of $25 and pay-per-view sports, without being connected to the internet.
