Very cool video! 7:18 Those seats are mostly likely closed off with the tray tables out to prevent people from upgrading themselves to extra legroom seats. I’ve seen United do this exact thing.
Im 95% sure they refer to NZ by its indigenous name because both places have a huge historical legacy of being settled by indigenous Pacific islanders/Polynesians - which still constitutes a major aspect of both places' cultural identities today. Same with Australia but idk if Qantas refers to NZ in the same way lol
