A $300 million-plus development that will transform how travellers arrive and depart from the Auckland Airport terminal, while paving the way for any future mass rapid transit, will get underway in June.

The Transport Hub, to be built in the footprint of the main international carpark, has been designed to allow traffic to flow through its ground floor. Two traffic lanes will enter from Ray Emery Drive into an undercover pick-up and drop-off area with a short covered walk into the terminal.
