It's going to be a sleepless night for many across the West Coast and top of South Island as a weather bomb continues to inundate the area.
Multiple rivers, streams and creeks have breached their banks and communities have been cut off after flooding has closed roads.
A state of emergency has been declared in Nelson after the Maitai River burst it's banks this afternoon and residents living nearby have been asked to evacuate.
The New Zealand Defence Force and Fire and Emergency are helping with the evacuations.
Further south a state of emergency is also still in place across the West Coast after severe weather warnings were raised to red for Buller and Westland until Thursday afternoon.
Nelson Mayor Rachel Reese is on the line now.
