Three window panels have been blown out of the Rotorua Novotel Hotel damaging three cars.
Rotorua Novotel general manager Edward Judd said he didn't know what had happened as he was on the other side of the building when the windows fell.
"We are just cordoning it off and making it safe at the moment and we will go from there. We have a manual we have to look at and then we have a whole lot of people we have to call and we will go from there," Mr Judd said.
