Multiple tornadoes have ripped through Kāpiti just over a week after two tornadoes left damage in their wake last Wednesday.
Tim O'Connor from auto parts workshop ACS Limited on Omahi St, Waikanae said he didn't know what was happening when a tornado came through around 1.15pm.
"I was upstairs in the office and I thought the weather was looking a bit odd so I raced downstairs and saw all this debris flying around.
"It just got worse and then the trees started coming through the building.
A number of trees have also been brought down due to the tornado, which would have damaged some cars as well, she said.
Wellington Region Emergency Management Office is urging residents in Porirua and Kāpiti to prepare for high seas from midnight tonight until midnight Friday.
Manager Jeremy Holmes said there was potential for more wave run-up and flooding, with coastal residents facing instances of coastal erosion, scouring, surface flooding and deposits of driftwood, seaweed, sand and gravel.
"We urge residents in affected areas to start thinking about ways to reduce impacts of swells on their property, such as using sandbags or barriers and moving things off their front lawn and driveway."
Kāpiti residents in Paekakariki, Raumati South, Raumati Beach, Te Horo Beach and Ōtaki Beach could see waves overtopping seawalls, causing surface flooding and debris disposal.
"We could also see debris disposal and surface flooding on State Highway 59 so we urge anyone planning to drive along this road to take care and use Transmission Gully as an alternative if they can, said Holmes.
