Wellington city centre's pretty much deserted, and Kaikoura is completely cut off by road, meaning also, that travelling north by road from East Coast Christchurch means going across the S.Alps to the West Coast.
Rail links from Picton (S.Island) to further south are also cut.
All of the southern end of the South Island (the Mainland) is now dependent on the West Coast road route north via the Haast Pass north of Wanaka, Otago, or via Arthur's Pass, or flying to get out of there and head to Nelson, Blenheim then to Picton and the North Island.
It's estimated that this EQ bill will cost NZ at least 2 billion dollars,....that's so far. Loss of business and incomes will further increase tgat amount as will the cost of relocating hundreds of families once more.
