Ms Pavlovic said previous productions that included Walking with Dinosaurs and How to Train Your Dragon had been "enormously successful" and Auckland remained a "key touring city" for future shows.
The show's publicist, Bridget de Launay, said the sales of tickets, which ranged from $49 to premium tickets that started at $110, were "below expectations".
"And I think there were a few other contributing factors: it's become quite a competitive market and [with] the extended summer I think a lot of people were focused on being outdoors and were not looking at indoor pursuits that early."
Aucklanders are spoiled for choice with shows and had the season of War Horse gone ahead it would have, in its final week, gone up against Broadway show Wicked, which starts in September.
Magic show The Illusionists: Witness the Impossible starts later this month while Disney on Ice: Princesses & Heroes starts in early June.
Ms de Launay said buyers who had bought tickets to the show, which was scheduled to start on August 20, would get a full refund.
