Auckland Zoo has been hammered by the recent storm, with a large gum tree toppling down into the Pridelands enclosure that is home to giraffes, zebras and ostriches.
Acting director Kevin Buley said in his past eight years at the zoo he had never seen anything like the recent damage from a single weather event.
"Coming in and seeing the damage is one thing but knowing all the animals are fine and no one was injured is the most important thing," he said.
Buley said it was standard procedure for staff to check the weather forecast daily and to secure the animals if there was an indication of an impending severe weather event.
All potentially dangerous animals had been confined before the rough weather hit, he said.
