To purchase an AT HOP card at Auckland International Airport (AKL), you should head to the Airpoints / Transport / Tourism information desk or specific convenience retailers located in the International Terminal. As of 2026, the most reliable spot is the Hub Convenience store located in the arrivals area, which typically stocks the blue AT HOP cards required for travel on Auckland’s buses, trains, and ferries. The card itself usually costs around $5.00 NZD (non-refundable), and you will need to add a minimum balance of credit to use it for your journey into the city. Alternatively, if you are taking the AirportLink bus to the Puhinui Train Station or the SkyDrive express bus, you can often find dedicated vending machines near the bus stops just outside the terminal doors. It is highly recommended to buy and top up the card before boarding, as Auckland's public transport system is largely "cashless" on board. Once you have the card, you simply "tag on" and "tag off" at the electronic readers to benefit from significantly lower fares compared to paper tickets, making it an essential purchase for any traveler landing in New Zealand's largest city.
