I was about to descend into responses to these issues directly, but it is obvious that no responder has any actual familiarity with New Zealand or its history especially as it deals with racism.
But I’ll add this. I live in a country right now, where a specific racial segment of the population has constitutional rights based on ethnicity to purchase homes at a lower rate, reserves 20% of the land for specific ethnic domain, bans all public debate of its constitutional privileges, imprisons or “reducates” any ideological dissenters, bars other races from public service, politics (despite being a functional democracy) and is the last nation not currently at war (or North Korea) that has not ratified any human rights documents (racism is actually legal).
I can’t go to the same universities as my neighbours (I’m too old anyway), my kids can’t go to specific schools. My children have lesser access to education, jobs and less free speech.
And all of this is in the constitution. That’s racism. Some idiot putting up a no spitting sign, doesn’t remove NZ from pretty high up the tolerance scale. And yes it’s had it’s problems as a country largely isolated with early 20th century migration, but that doesn’t disqualify a nation from exhibiting some extremely phenomenal acts of racial integration and harmony.
