Like JonB, I find those Air New Zealand adverts to be highly intrusive, also I suspect they are chewing through my data cap and clogging up my ADSL (, UFB 'after June 2019'
) connection.
I only see them at home, despite being a subscriber, because when I'm on GeekZone from work my employer uses an adblocker that I can't turn off (and frankly I don't want to) and can't configure for 'whitelisting'
