Kia Ora,

I think you are right, mate.
Wasn't too long ago, either, that people would leave their houses unlocked, and their car keys in the ignition. As recently as 1989 (my first trip to NZ) this was common. Now, don't even think about it, or some scroat will swipe your goods.
Grafitti, too, was uncommon back then. Now it is everywhere.
It took very little time for Crime to take off here and get beyond our Police capabilities to control.
