Access to that lounge was $50 at the door for passengers travelling on any airline and any class of travel.
The new Strata Lounge will be bigger and able to seat 180 people. It is part of an upgrade of the main terminal building and airfield areas where the airport company says it is spending $1 million every weekday.
It copped criticism during summer as some passengers and the growing number of workers in the area found it difficult to get to the airport.
The new lounge has six ''relaxation pods" or bookable, acoustically treated alcoves where people can nap between flights. There is also a dedicated children's play space away from the business zone.
A larger facility is at Level 2, near the other premium lounges of Emirates and Qantas airlines.
Jason Delamore, Auckland Airport's general manager - marketing and technology, said the Strata Club was one way the airport was investing to getting to know its customers better.
''It has been designed by our customers for our customers, and is part of an extensive programme of short- and long-term improvements."
