The Education Television and Video Communications Trust was established in June 2010 by e-cast Ltd as a not-for-profit Charitable Trust to manage the development and distribution of the off-air broadcast recordings services to Schools, Kura, Polytechnics, Wananga and Universities throughout the country. The Trust has been approved by the Minister of Education and Screenrights to operate as an Education Resource Supplier under the Copyright Act S.48.
Basically can watch freeview TV and a bunch of shows including Game of Thrones. Seems old uni/school logins will get you access as well.
I'm a teacher so logged in using my school name - found a programme but it said "your school does not currently subscribe to tv recordings." Guessing that universities/high schools might be more likely to subscribe.
