Clean-up is underway after heavy rain battered parts of the country this week, with Nelson the most hard-hit.
Around 570 people were evacuated from their homes since the heavy rain began, with further evacuations expected, the Nelson Tasman Civil Defence said on Saturday morning.
A further 50 to 90 mm of rain was recorded overnight across the Nelson, Tasman Marlborough and Taranaki districts, MetService said.
"Some high elevation stations even measured over 100 mm since midnight - a lot of rain to fall on top what has already fallen."
In the Rai Valley, an elderly couple have been left homeless after their house was swept away by a slip.
