Auckland International Airport is New Zealand’s busiest airport and is the main arrival point for most visitors to the country.
There is a free shuttle bus service between the international terminal and the two domestic terminals, which operates 6am–10.30pm; alternately it is about a 10-minute walk between the two terminals.
The quickest way to travel between the airport and downtown Auckland is on the SkyBus, which runs 24 hours per day. The SkyBus leaves from 396 Queen Street in the city centre, although there is also a shuttle bus that connects the Auckland city SkyBus terminal with hotels and hostels in the city centre (although the shuttle bus only runs Mon–Fri noon–7pm). The SkyBus costs $18 one-way or $32 return.
A cheaper option is to take a train to either Onehunga or Papatoetoe and then hop on bus route 380. Bus 31 also runs between Papatoetoe station and the airport. This option will take considerably longer than the SkyBus, but is much cheaper at $9–10.50 (or $4.85 if you pay using an AT Hop card). The trip between the airport and the city centre crosses three fare zones.
