New Zealand really is a much prettier version of the UK. The landscapes are breathtaking and the vast majority of people I met (albeit I spent most of my time on South Island) were from the UK.
By sheer luck, I overhead a short conversation on top of Queensland Hill about a road closure. After descending, I did a quick search and realised Highway 6 was closed near Haast. This meant the whole of the West Coast was really hard to get to, with the only alternative being a 15 hour detour.
Though the highway agency said the earliest day it would reopen would be in a few days time I did not want to risk it and proceeded to rebook all my accommodation. This eventually turned out to be the right decision as that section of road was closed for nearly 2 weeks!
So no helicopter ride at Franz Josef. I rerouted and planned to visit Lake Tekapo and Arthur's Pass. The comments online of Arthur's Pass being scary to drive unsettled me, but I didn't have many alternatives. I had to just go for it.
At least the two train rides I had booked was still scheduled to run!
