Watch: 'It looks like a tsunami' - tidal surge swamps beach near Wellington

Yesterday's wild weather in the lower North Island has been highlighted by an astonishing film recorded at Raumati Beach, around 50km north of Wellington.

Nicki Munford-Gibbs posted on the Wellington Severe Weather Reports Facebook page a video taken at high tide.

It was taken at 12.30pm from a pedestrian bridge at the Kapiti Coast beach.

It shows a tidal surge swamping the beach, going up on to a grassy verge and covering part of a car park.

The water then heads up a river.

"It was a little wild to say the least," Nicki Munford-Gibbs wrote.

The clip has had close to 1000 Facebook shares and generated dozens of comments.

Shirliz Gasca wrote that the surge "looks like a tsunami",  while Nessie Allan posted "Oh my goodness, scary stuff".
