Two tornadoes ripped through Auckland and Papamoa, near Tauranga, on Saturday morning.
Multiple buildings and roofs were damaged in East Tamaki, south Auckland, with store owners now left to clean up the damage.
Residents in Otara and East Tamaki shared videos of the tornado swirling, carrying up debris, as witnesses looked on in horror.
"WOW! What a way to start the day!!" wrote Renee Williams, who shared a video of the twister on her Facebook page.
Fire and Emergency said there have been some reports of "major structural damage" from the Auckland tornado.
"We've got about 10 calls in the area, just going from one job to the other, assessing the damage," said spokesperson Craig Dally.
"[The calls are] mainly to roofs lifted and a few trees down, damage to industrial buildings in the area."
He's urging residents to stay indoors.
Around 10am on Saturday morning Bay of Plenty news outlet SunLive reported a tornado in Papamoa.
A reader told them they saw roof tiles, gutters and TV discs coming off houses and a trampoline flying through the air.
Roadworks signs were also flung through the air.
Multiple roads have been affected and a tree is down in Topaz Ave.
These incidents come after a tornado in Mangawhai on Friday night which was followed by rain, leaving houses water damaged and furniture destroyed.
