The number of domestic passengers passing through Auckland International Airport is down for the first time in more than a year and a half.
The airport company says patronage fell 4% to 471,000 in November, compared with the same period a year earlier.
Strong domestic travel has offset some of the fall the airport has seen among international visitors, as the global slowdown curtails holiday plans and business trips to this part of the world.
Meanwhile, the number of international passengers fell 2.5% in the month, with fewer visitors from Britain, the United States and Asia.
The number of tourists from Australia bucked the trend, rising nearly 4%.
