New Zealand is a bad example to use, given that it's one of the few cases where settlement was based on a non-coerced treaty intended to actively integrate the native people as equal citizens with the settlers. While the NZ government later spent about a hundred years ignoring the treaty and treating the Maori badly, the treaty itself, the process that led to it, and the actions of the settler leaders at the time of its signing had a legitimacy that most other cases of colonization and settlement (including that of Israel) have generally lacked.
