紐西蘭移民局對奧克蘭機場國際中轉的規定, 沒有隔夜與否一說(所以客服說隔夜中轉行李或不能直掛一事,存疑),只有24小時限制,參見移民局 Transit through New Zealand規定: As a transit passenger you can only travel through Auckland International Airport where you must stay in the transit area of the airport or on board your craft. Normally you must spend less than 24 hours in transit in New Zealand. https://www.immigration.govt.nz/new-zealand-visas/apply-for-a-visa/tools-and-information/your-journey-to-new-zealand/before-you-travel-to-new-zealand/transit-passengers
