I'm planning on GETTING OUT of NZ as I believe almost all the country will sink during a pole-shift. The country is very flat and cannot survive tidal waves - I discovered the highest South Island town is Arthurs pass (its tiny with a few dozen people who live there year round). The most worrying thing is the North Island is full of VOLCANOS (Auckland city has around 10). There's a massive earthquake fault running through Wellington & the South Island - see image below (sorry the faultline through Wellington is NOT shown here).
The North Island has huge volcanoes running down its middle (one erupted in the 1990s & another erupted in the 19th Century destroying the "Pink & White terraces" - the 8th wonder of the world). Here's a picture of the Kermadec Trench just to the right of the North Island & you can see "train tracks" to the North of the North Island - the huge volcanoes run in the middle of these train-tracks down the North Is - see picture:
You'll need to research some of my above points yourself as I can't explain everything in detail in one post.
