Auckland airport hopes to welcome 40m passengers by 2044.
To achieve this the airport is going to be developed enormously with an investment of approximately NZ$2.5bn over the next 30 years.
Among other benefits this will create an estimated 27 thousand jobs in construction for the local area.
The city was recently named in the top 10 in the world by Lonely Planet and third best city for sports after London and Sydney.
It achieved a record 93% hotel occupancy in February this year.
