New Zealand has much stricter filters for immigrants.

Tautologically: good immigrants are great and bad immigrants are terrible. I certainly know a few awful immigrants too.

30% of our population was born overseas. It seems to be working fine for those born here and for the immigrants.

Young New Zealanders emigrate, and existing immigrants get older so NZ has an ongoing need to have more immigrants.

People want to come here so we have the luxury of setting filters. I'm not sure what will happen when other countries start competing harder for the "better" immigrants.

Australia is similar but it has less trouble with losing its young people - it gains a lot of New Zealanders because it is a wealthier country with better weather (but bitier fauna)
