It is very frustrating to hear multinationals opening offices in Sydney and saying "New Zealand people can work there too, it's all the same" when it's not. American companies open Canadian offices all the time because the cultures are different. Australia and New Zealand have the same relationship: same language, different cultures.
It grinds my gears to this day because I would love to return for good, but I can't/won't give up my career, and I don't really want to move to Sydney. I want to move to New Zealand.
EDIT: N/M looks like I can get in easily if I'm offered a job by an NZ employer listed as an "absolute skill shortage", so I guess I answered my own question. I'm using this tool for anyone curious: https://www.immigration.govt.nz/new-zealand-visas/apply-for-...
