"From an industry point of view it's important to get people watching more video on broadband. The future of our business is video entertainment."
The free Lightbox package has been welcomed by Internet New Zealand and the Telecommunications Users Association of New Zealand, which said it signalled greater options for consumers as internet services improved.
Spark is encouraging customers towards higher-cost all-you-can-eat broadband plans. The move coincides with the company reducing the price for its uncapped plan from $109 to $99 a month and the decision to stop marketing the 150 gigabyte broadband plan from next month.
Customers will be able to pay for packages of 40 gigabytes and 80 gigabytes, and the next option will be to buy an unlimited broadband offer to fit the growing number of online entertainment options.
Sky chief executive John Fellet said the free Lightbox offer was "good for Sky". With Lightbox free, Spark customers might be willing to buy another pay service, such as Sky.
