Today, Sky said the merged Lightbox and Neon service will launch on July 7.
"It will no longer be included free of charge in Spark mobile and broadband plans," a Spark spokeswoman confirms.
But Spark customers will be able to buy the merged service at the discounted rate of $9.95 per month (Neon usually costs $13.95, with new-release movies costing extra).
"Because we have made this change all customers are entitled to exit their Spark plan or leave Spark entirely if they would prefer until 15 July, without paying an early termination fee (for fixed-term plans) or a notice period fee (for pay monthly plans)," a Spark spokeswoman told the Herald.
The merged service will retain the name Neon, but have content drawn from both Neon and the old Lightbox, and use Lighbox's interface, according to a social media post by Spark.
Spark claimed more than 300,000 users for Lightbox at times.
But the telco never detailed how many were Spark customers who got the service for free, and how many were with other ISP and paid to access the streaming service.
At the time of its sale, there were 130,768 active Lightbox users, including freebies.
Wealth manager Jarden has predicted that Spark will also exit sport. Spark CEO Jolie Hodson earlier told the Herald that was not correct but also declined to say if her company would bid for Sanzaar rights next time around, saying it was too early to make a comment.
