Interestingly, this exact pass feature is used in EU.. except they have different options for zero rated services, such as youtube under video (which vodafone do not)
It is a rather bizarre selection. Spotify is not included in the music pack, which I would imagine would be used more than the listed apps combined. Video includes Netflix, Sky Go/Neon and TVNZ, but does not include Lightbox (owned by Spark), ThreeNow Māori TV, or Youtube. Also from the fine print "Where video content is included, it will be optimised to be similar to DVD quality" (which I assume means the SD version of Netflix)
from the music pass section " Apple Music, iHeartRadio, Rova, SoundCloud, Tidal, Spotify and more coming soon "
