While being Serbian, with family from Croatia (some of which are now there dealing with corrupt government employees accepting faked papers to transfer land ownership). Means I totally get the pessimistic and corruption focused view of the world/governments/etc.
We just don't have enough info to go into such tabloid level direction for this guy.

Maybe his wife or one of grandparents came from N.Z. and he can live/work there without visa?!?
Maybe it's intra-company transfer (like how many Googlers from "east" start in EU/Canada, and then get transferred to USA after a year or two) there?

Either way - it's still pretty shitty "Do as I say, not as I do" behavior from the guy, and Google itself (Hey, here are great tools for remote collaboration with your team - as long as you're not a Google employee).
I am also sorry that your family is dealing with Croatian government corruption, which is never OK. I hope your family is able to get a good lawyer, that will protect your family’s interests and needs.
People have shown that NZ has investment pathways. It’s entirely possible he used them. If you disagree with those, fine, that’s your call. However, that doesn’t make it corruption, and you shouldn’t frame it as such.
