Elsewhere, a week of brilliant weather would continue for most throughout the country.
"It was a fine start for a lot of people," Metservice meteorologist Tahlia Crabtree said. "It's still pretty summery weather and warm across the country."

Rain would batter those on the West Coast the worst. There would be snow about the ranges and winds would be strongest in eastern areas and Cook Strait.
However, the storm could enhance the summery weather for some areas of New Zealand.
