Severe Tropical Cyclone Atu is continuing to intensify with Fiji's Meteorological Service now classifying it as a category four storm.

It is forecast to strike Vanuatu and WeatherWatch.co.nz predicts while it will brush New Zealand, it will pass here out of harm's way.

However big seas are still a possibility between Northland and East Cape from Wednesday to Friday.
