Large swells from Cook Strait closed Moa Point Road earlier this morning, at the southern end of Wellington Airport.

Wellington City Council said the waves had brought boulders, rocks and other debris on to the road.

Huge seas generated by the same storm that has affected New Zealand all week are responsible for the big waves hitting the North Island’s south coast today.

Offshore swells are 6 to 8 metres high.  The same same swells hit the western coastline at the start of the week, and at the time WeatherWatch.co.nz said the area of huge swells was the largest on the planet.

The council advised motorists to avoid south coast roads especially in the Owhiro Bay and Island Bay areas where kelp, rocks and other debris had been washed up and was making driving conditions hazardous.
