Cant find TuneIn station on MusicBox

Hi,

First time user, looking for a particular TuneIn Station, The Rock, The Rock FM 90.2 FM, Auckland, New Zealand | Free Internet Radio | TuneIn
which doesn’t seem to be there when I search using the Search function on MusicBox.
Am I just being super blind, or is it not there? What am I missing?

Thanks
Tim
