Niblock said growth had been fuelled by the addition of more content over the year as well as the use of express services, where the latest episodes of a show could be viewed within a few hours of it being screened in the US.
She said although a lot of the major television shows did well, New Zealand content was also highly viewed, something she hoped to boost in the future.
"Local Kiwi content does really well for us and we'd love more content," she said.
"And we'd love to be in a position one day to make our own content but we're probably a little bit far from that yet."
Lightbox's parent company Spark, is currently going through the courts with several other companies including TVNZ, Mediaworks and SkyTV to try to stop the use of Global Mode - which allows customers easy access to overseas content.
The companies say the use of Global Mode is illegal and infringes on copyright, however Niblock said regardless of the outcome, it would be good to get some clarification for the company.
"It's all in the hands of the courts at the moment but it's very simple for us, we pay for exclusive rights so all we are doing is exercising our ability to understand how exclusive those rights are," she said.
"We want to understand what the outcome of that is, either way whether we win or lose it's good for us because at least it will be clarified."
Niblock said the company had paid for exclusive rights and this was being undermined by access being allowed from other countries.
She said there had been issues with users from outside of New Zealand accessing Lightbox's services, in particular its PremierLeaguePass sports service, however she said this was usually shut down pretty quickly.
"The idea is that when you sign up for a service you sign up to the terms and conditions that you're allowed to use the services and you are in that territory," she said.
"And that's true of our competitors in other territories so that's part of our issue around global mode."
