Freeview NZ XMLTV EPG Listings
Full Freeview NZ 7 day EPG XMLTV files.
It should automatically bring in new channels and update icons when they change.
It has the channel number as the first 'word' in the channel name.

If you want to use your own names, or icons, or channel numbers - then un-check the boxes.

The EPG files are updated hourly.
