Tourism Holdings says its first-half result will be down on last year's as sales suffered partly because of the Rugby World Cup and the weakening US dollar.
Addressing shareholders at the company's annual meeting in Auckland, chief executive Trevor Hall said that while first-quarter trading had met expectations, sales during October and November had been "disappointing".
"It is too early to tell whether this will be characteristic of the full three months."
One factor that had affected trading over the period was New Zealand and Australian rugby supporters squeezing airline seat capacity from the Northern Hemisphere.
"The ongoing collapse" of the US dollar against the euro was also making the US a more attractive tourism destination.
