Yes HK definitely has lost a lot of its shine for me. Of course there are things I will miss when I leave which is hopefully soon but I am happy to remedy that with an occasional stopover on the way to more interesting places from time to time.
I have a good friend that retired to the island a couple of years back. He is not missing HK at all and figures he pulled the trigger at the perfect time. I can't disagree with him.
For the NZ thing. When in doubt always best to say NZ, it's less insulting than the other way around. Same for CAN-US, always best to go for Canadian first
