Just a chime in, got a call from mum in Hastings, freeview NZ guide not working since 1pm on DVB-T.
I'm also in Hastings and checked one of my only TV's, sure enough the guide button doesn't work.
For me Panasonic, Samsung TV's and Panasonic recorders not working.
A facebook post also indicates an issue from other users.
Anyone else can check and chime in location?
