The wild weather that has battered the South Island's West Coast is tracking north - bringing rain and possible thunderstorms to the North Island.
A "red warning" has been issued for Buller and Westland - as heavy rain caused flooding, slips, major road closures, evacuations and left people trapped on the roofs of their cars needing to be rescued by helicopter and front-loader truck.
A state of emergency has been declared in Marlborough by the region's deputy mayor Nadine Taylor, while hundreds of properties have been evacuated. A state of emergency has also been declared in Buller - where last night more then 820 people were forced from their homes.
MetService said the bad weather would move swiftly up the country today - bringing with it periods of heavy rain to much of the North Island.
