Hackers uploaded a pornographic video which screened on Asics' central Auckland promotional screens to shocked shoppers and pedestrians early on Sunday morning.
Staff at the Shortland St store confirmed the hacking but said they could not make any further comments about how the inappropriate content appeared on the large screen above the shop entrance.
Dwayne Hinagano, a security officer who witnessed the screening, said an explicit sex video which ran for nearly two hours were seen by shocked passers-by when they walked past the sports retail shop.
"It's not something anyone who comes to Queen St early on Sunday morning would expect," Hinagano said.
