Why register for a Freeview account?
Up to date, Freeview hasn't asked viewers to register or create an account to access any content. But you may have needed to register for a TVNZ account to watch TVNZ OnDemand.
With more broadcasters likely to join the Freeview On Demand platform and likely to introduce their own registration requirements, rather than you having to login to individual broadcaster apps, the Freeview account would provide access to all broadcaster content, bypassing multiple logins and streamlining the registration process - making it easier for you to start watching your favourite shows.
The registration also means Freeview can provide viewers with their viewing history, to resume viewing easily across sessions. It also allows Freeview to roll out more customisations and personalisation features in the future.
