Personally, I find our anthem so boring that it's impossable for me to be inspiried or even mildly interested whenever it's played. Compared to some of the more powerful and emotive anthems from around the world, like say the French or the South African, or even the American anthem, ours just seems dull and doesn't say all that much about our nation or national identity.
Still, it's better then "God save New Zealand". God won't defend New Zealand in a war, we will. v.v
I have little problem with the flag, except that I'd suggest incorporating something Aboriginal along with the Union Jack of Britain onto it. To better represent our history. Maybe not the Aboriginal Flag itself, but something.
Edit: On top of all that, I find many of the lyrics insultingly wrong.
