Updated route

Here's our updated route. Once we decided not to go up the West Coast because of weather, we headed back inland and east, retracing our route from Christchurch. We went further north from there. 

The road along the east coast is one of the most beautiful seacoast highways I've ever been on. Only rivaled by parts of Oregon on Highway 1. Just stunning. 

Then we headed back west along the north coast to Nelson. That's where we met our most twisty-turny road. I think we were all about seasick when we got there. 

Then we headed back east to Picton, took the ferry to Wellington, and went north to Auckland from there.
