Hi Jay
I did the same move a few years ago, luckily I happened to speak to LG in the Uk who told me a UK/EU TV won't work in NEW ZEALAND - unless it's connected to a sky box or something like that - the core function parts (app store, channels etc) simply don't work. I latterly also discovered the same thing when moving from Australia to NEW ZEALAND - so there is a theme here. Basically I think LG are delivering a very budget service for NEW ZEALAND consumers - the firmware updates do not include functionality improvements offered/made available in other countries (ie, Alexa)....
My decision is my next TV will not be an LG, they simply don't support updates for long enough to make them worthwhile.
