is running.
It takes about 30 minutes, about the same time as a taxi. The fare is 10 NZD one way for adults. You can pay by cash or touch credit card. AX is highly recommended as it operates on a regular schedule and approximately every 20 minutes. Courtney Place at Courtney Central is the closest stop for Takina and TePaPa. It is the 4th station from the airport.
