Actually both.

Actually no.
DOT regulations are generally based on either the origin or destination (one has to be within the U.S., including territories).
EC regulations are generally based on both the origin and the airline's country of registration (either one within EU).

Generally, to ensure compliance, airlines will comply the law that is more restrictive to its operations. So if NZ government says vouchers work but not USDOT, then NZ will follow USDOT regulations for anyone who are covered, and follow NZ government's policy for those who are not covered by USDOT regulations.
