So would I have to buy from New Zealand region or could I just change the region on my Xbox and play when it goes live NZ time?
When i buy Forza from Singapore, i change location of console to Singapore, enter credit code, purchase game, download game, switch console location back to UK.
Forza always unlocked Singapore midnight timezone, never unlocked by console location, only by purchase location from my testing.
Also, i've purchased Forza horizon 3 from Singapore, then purchased DLC from USA, works perfect
EDIT: how much is Destiny 2 in New Zealand?
