It's absolutely necessary. You have to get those terrorists off your island (LOLOLOLOL) or else who knows what they might do? They're climbing in your windows and snatching your peoples up. And besides, if you're doing nothing wrong, you should have nothing to worry about. Only criminals would care about surveillance; are you all criminals?
I remember when I used to think this way back in my HS days
Seems this kind of garbage is spawned only by fear, or, as American politicians like to put it, "Terrorists win!" Anyway, remember, folks: freedom is slavery; ignorance is strength; peace is war; and Big Brother is watching you.
...seriously, what would terrorists want with a little island like NZ anyway?
Plus, hey, you know you can trust all your elected officials and regulatory and administrative people. You know they need access to everyone's emails and personal data just in case some rightwing or leftwing nutcase accused them of some totally bizarre thing like theft or corruption.
Look, the little people need some laws to protect them, sure. So we probably need a bunch of PR and noise and some nice sounding legislative package and then a campaign to tell them over and over how it protects them. But <<wink wink>> you know we need to have a group of exclusions in their for the duties of our government agencies and law enforcement personnel.What I'm indicating is that legal code is not going to really help us. Just like with the "Can Spam" act supposedly to prevent spam, it allows it. Just like the US Post office is your junk mail provider. Just like the HEPA privacy act codified all the exceptions to your privacy.
You need to do it yourself.
