"New Zealand's crime statistics are compounded by the over-representation of Māori. Though Maori make up only 12.5% of the general population aged 15 and over,[28] 42% of all criminal apprehensions involve a person identifying as Maori, as do 50% of those in prison."

No matter how you interpret that, there is something fucked up:

"The figures lend themselves to extremist interpretations: at one end, some accuse the criminal justice system of being brutally racist, as either intentionally or unintentionally destructive to the interests and well-being of Māori as a people. At the other, there are those who dismiss the entire Māori race as constitutionally 'criminally inclined'."

NZ has quadruple incarceration rate compared ton Finland, Japan or Iceland, which you could claim to be homogeneous.

I said NZ was a peaceful society - it is. I said that NZ was multicultural - it is. I didn't claim that we have no racism and I agree with you that the over-representation of Maori in the prison population is a problem. However, it was only the first two claims that I actually made.

Yea so is Sweden, Norway and a ton of other places. FOR NOW... That is the whole point.
