As the floodwaters in Buller disappear, damage caused by the severe weather that hit the West Coast on the weekend becomes more evident.
Hundreds of people were forced from their homes when heavy rain caused flooding, closed major roads, submerged fields and prompted Buller and Marlborough to declare local states of emergency.
Buller mayor Jamie Cleine said around 22 homes in his district were "red stickered" yesterday - meaning their occupants couldn't return home to live before repair work was done.
There were around 100 people still staying in the area's three evacuation centres, including a school where people were camped out in classrooms.
Relocatable accommodation units would be ordered to house some people in the medium term - as some residents faced months out of their homes, while others may never be able to return to their properties, Cleine said.
The focus for the coming days was to continue assessing the damage to homes - with Cleine predicting the number of "red stickered" homes likely to be more than 100.
"A lot of the red-stickered houses are dotted [around]. You could have a red stickered house and the next one is fine. It came down to the luck of the draw," he said.
Floodwaters in the area had receded - while the streets were "a hive of activity" with people pulling carpet and furniture from their homes and piling it on the streets.
"The streets are all looking a little dirty and dusty," he said.
MetService has issued a "heavy rain watch" for Buller and the ranges of Westland, with periods of heavy rain forecast and thunderstorms possible for inland areas.
Forecaster Sonja Farmer said a front would move across the South Island today and Thursday morning - bringing a brief burst of heavy rain.
"It's not expected to be exceptional but because of the recent flooding, it's pretty much a precautionary watch," she said.
The deluge on the West Coast elicited a multi-agency response - including from the New Zealand Defence Force, which deployed more than 30 personnel and soldiers, four Unimogs, an Air Force helicopter and other vehicles.
Defence Force personnel did emergency food drops to rural areas, cooked for up to 300 emergency responders and assisted with the evacuation of more than 800 properties.
Buller Health, a DHB health service provider for Westport and Northern Buller, is also continuing to deal with the damage caused by the flooding - including replacing damaged electrical cabling and switchgear.
Two patients were being cared for in a makeshift ward facility at the local community club, while acutely unwell people were being diverted to Greymouth's Te Nikau Hospital, the DHB said in an update.
West Coast Emergency Management said 89 houses in the West Coast had suffered severe or total damage (red category) and 400 suffered moderate damage (yellow category).
Recovery from the weekend's storm also continues in Marlborough - another badly impacted area - where residents were evacuated and roads closed.
"We are working with many Marlborough-based agencies, organisations and iwi to get our region back up and running," Mayor John Leggett said.
In Nelson, the stormy weather washed away a section of footpath on Rocks Rd, with a temporary footpath erected on Monday night, the Nelson City Council said in a Facebook update.
Construction of a permanent path would take several weeks to complete.
