Flood flows on the Buller River were the largest of any river in the country since 1926 after the deluge last month. The stand-out rain event between 15 July and 18 July brought over 690mm of rain to parts of the West Coast in under 72 hours.
Along with the West Coast, well above normal rainfall (more than 149 percent of normal) fell in large areas of Marlborough, Nelson, Tasman, Canterbury high country and northern Otago.
Parts of coastal northern Northland, inland Bay of Plenty and around Wellington central and the Kāpiti Coast had above normal rainfall.
