Why is content changes being made to Freeview On Demand?
Freeview doesn’t own or have rights to the on-demand content from TVNZ. That content is delivered through Freeview On Demand at the broadcaster's discretion, and likewise can be removed at their say so. In this instance, TVNZ has decided that TVNZ OnDemand will be the home for the streaming of its on-demand content going forward.
But don't worry, all the content will still be available, just in two different places - TVNZ OnDemand (for TVNZ OnDemand shows) and Freeview On Demand (for everything else).
