Fellet said he would have liked to have seen Neon running as far back as June. The delay has enabled the Spark service Lightbox to get up and running.
Sceptics say that Sky is in no rush to launch the $20 a month Neon service because of the tricky marketing task to ensure it is good enough to beat competitors such as Quickflix and Lightbox without drawing customers away from the more lucrative main Sky service.
Neon will not be showing sports.
On Thursday, the internet TV subscription sports channel Coliseum announced it would be entering into a 50:50 joint venture with Lightbox to be called Lightbox Sport.
No date has been set for the new arrangement and the new merged firm has not resolved how the pricing structure will be set up.
Coliseum is best known for streaming soccer games from the English Premier League, French Rugby 14 and golf.
While comparatively small compared to Sky - and without the key sports like rugby league held by Sky - Spark backing will give Lightbox Sport the financial firepower to compete more fully for sports rights.
The US operator Netflix is planning to introduce a service in March into the New Zealand market, which is fast becoming highly competitive.
