Air New Zealand's patronage fell in November, with long-haul routes particularly hard hit.
The airline carried 1 million passengers in November, 1.1% less than in the same month last year.
Domestic patronage slipped 0.7%, but trans-Tasman Pacific passenger numbers rose more than 4%.
Long haul passenger numbers were down 12% on last year, with the North America UK route down more than 10%.
The airline says the effects of the Christchurch and Japan earthquakes continue to affect passenger numbers on the Japan routes.
