More than 220 homes near the Maitai River were evacuated yesterday as the river surged, and ten more in the Tahunanui Hills joined them overnight because of a slip.
The mayor, Rachel Reese, told Morning Report the region isn't out of the woods yet, with poor weather continuing and high tide expected about midday.
She says when some people return home, it won't be a warm welcome.
NIWA's Chris Brandolino told the programme the Nelson-Tasman region can expect heavy rain through to sunset and then a lull before it picks up again tomorrow.
