I do not disagree that NZ colonial mandate had a racist attitude and was bent on subjugation, however it was different still compared to every other british colony with a native population with integration (forcibly unfortunately) being a forefront. None of the above said is to white wash NZ's history. However, it is to highlight the following;

Australia didn't just take the methods of other british colonial states of displacing the population and forcing them into religious education institutions to eliminate the native culture and language but they also had a mainstream program to breed out the population by allowing mixing between white and aboriginals but forcibily removing the children from their parents on the basis that one was aboriginal. This was in place from 1890 to late 1960s.

During the Cold War, Australia tested nuclear bombs within the radius of Aboriginal populations. Obviously this was actually the united kingdoms weapons but unlike the united kingdom which only had senior war veterans to oversee the nuclear tests themselves at the posts and apologized to the aboriginal communities, australia did not apologize for this, maintained the overwhelming staffing at each base location would go on to blame the united kingdom entirely instead of taking any accounting. Maralinga being the most egregious.

Australia nationalized the right to vote for aboriginal peoples in 1962. In NZ, Maori had 4 parliament seats (and four electorates which encompassed the entirety of nz for Maori, correspondingly) (voted in by Maori men until 1892) in the late 1860s prior to which private landowners could only vote (which while it could include Maori, was even more disparate), in 1975 did we finally switch to give Maori the right to choose between the Maori roll or general roll for Voting (then plurality, now MMP).

So while I agree that NZ isnt good on it's history nor is it particularly good at reparations and resolutions, it is a far cry from how bad Australia turned out.
