Help Katrina Recover from the Kaiaua flooding

I've created this page to try help my Mum, for the second time in 9 months mums house has been taken out by flooding from a storm . This time the flooding has come from the sea and the saltwater, mud and sand has completely destroyed her home, taking out walls and ruining everything inside the house, the smell is extremely bad from the thick mud that has coated their house and belongings. They have had to leave their home with nothing as its all floated away and been ruined. Sadly they have no contents insurance and a very small amount of cover for house insurance that’s not going to cover the damage .It's going to be a long road to getting the house fixed and things replaced. Its honestly just so devastating. Any help is so so appreciated.
