There's something about the Kiwibank anti aussie ads (join the resistance) that hasn't worked for me. You don't need to bring others down to boost yourself up. The unique offering of Kiwibank is well known, they don't need to thrash it, it's overkill and it a bit like, "Methinks he doth protest too much".
The other angle I dislike is the use of D-Day and WW2 resistance imagery. Why go that way and make fun of the people that died in horrible circumstances, and the many more adversely affected, around that world event? Why go there?
I generally like Kiwibank and I believe in going as local as you can for everything.
The news that Kiwibank is using an aussie call centre just increases my unease.
Tidy up your act Kiwibank, walk the walk don't just talk the talk.
