Spark's new internet television service is aiming to attract at least 70,000 paying customers by the middle of next year.
The venture, Lightbox, has launched in beta mode and is due to become available to the wider public at the end of this month.
Due to have 5000 hours of content, Lightbox gives "all you can eat" access to its content on up to five devices and named hit shows Arrested Development, Outlander and 24 among its "exclusive" offerings.
The service is tipped to challenge existing pay-television service Sky TV and provide an alternative for Kiwis who access overseas services such as Netflix and Hulu through backdoor routes.
Spark managing director Simon Moutter said, when reporting the company's full-year result today, that Lightbox aimed to get 70,000 customers by June 30 next year.
