However, a function was held last night and details of a few happenings would be released later today.
The first terminal served both domestic and international passengers for more than a decade.
A new international terminal was opened in 1977 by Prime Minister Sir Robert Muldoon.
Work has begun on a $180 million development which will double the size of the current international departure lounge.
