There are a number of resources regarding government and travel restrictions. We've outlined them for you here.

All passengers arriving into New Zealand must register their managed isolation accommodation requirements to be permitted to board their flight. A Managed Isolation Allocation System Voucher will need to be presented at check-in. Accommodation can only be booked a maximum of 3 months in advance. We highly recommend checking managed isolation availability before booking your ticket, and registering as soon as possible. For more information visit the MIQ Government site
