Roads around the Nelson-Marlborough region are an active construction site of flashing lights as crews work to get the crucial links re-opened after major flooding.
Council officials have been out assessing the extent of the damage on the roads today.
At least 120 homes in Nelson have been red stickered, which means they're too unsafe to enter.
Another 100 houses have been yellow stickered - so residents can go home temporarily but may need supervised entry.
Emergency Management Minister Kieran McAnulty says most of those out of their homes are staying with family and friends.
