This flood caused many people surfing in Karitane's coast to panic. The sponge is high with a length of about 100m, News reported.

"I've never seen such an image in 10 years of surfing photos , " said 30-year-old photographer Chris Garden from Dunedin.

Chris Garden also said that there are 3 "innocent" guys surfing the waves in 20 minutes to return to the shore. "The sponge didn't last long and I was lucky to record that moment," he said.

According to scientists, sponges occur when last week's floods flooded the sea. Strong winds carry waste, plankton, dead fish, floating trees and become foam and follow the waves drifting to the coast.

The amount of sponges spilling onto the beach depends on many factors, such as coastal terrain and weather conditions.
