The construction of a new $17 million international terminal for Queenstown's Airport is underway.
The 4,080 square metre extension will increase the current building by a third, to meet the growing numbers of overseas visitors.
Queenstown Airport chief executive Scott Paterson said the new terminal will double the size of international operations.
He said the interior will be developed in three stages and include new arrival and departure lounges, a customs area, retail stores and office space.
Mr Paterson said the first stage of work is expected to be completed by mid 2015.
