It is rumoured (by locals) that Kim Dotcom has been allowed to reside in New Zealand (being a German/Finish) on the basis that he spent his money in New Zealand. I don't think they are in a rush to extradite him to the US, and the US will not come after NZ for the money spent.
How is that a rumour? That's literally how the Investment 1 and 2 resident visa worked before 2022 when they finally scrapped the program. You invest at least NZD $750,000 in growth investments. Given that that's 450k USD, and kim dotcom's net value was quite a few million, that was barely an inconvenience. Then he just needed to spend the majority of his time in NZ to qualify for citizenship.
NZ is not a random atoll island in the Pacific. Kim Dotcom is wealthy, but still way far, way far from having enough money to bribe the whole country like that.
