PC Access
This is where things get silly. Amazon has a free Kindle for PC application to read kindle books on your PC. This is not accessible, but they do have Kindle for PC accessibility plug in. This works well, but you cannot download it in New Zealand. It is currently available in Australia, Canada, U.K. and U.S. You can download the Kindle for PC application in New Zealand, just not the accessible plug in. We have no idea why. Technically you could download it from overseas, or get someone to send you the file, but this could be in breach of your terms of service with Amazon. We haven’t had an answer from them.

How to unblock the contents on Amazon’s Kindle?
Because of Amazon’s tracking system on your IP’s origin, the solution simply consists of switching it to an US one. A VPN is an ease-to-use application which allows you to connect to a VPN server which provides you an IP according to its country location.
Thus to unblock the Amazon’s Kindle contents, you just have to connect to an US server! However you also have to get an Amazon US account, so here is a way to proceed:
Create an account at the Amazon web store at amazon.com
Select the table ‘Manage your Kindle’ and then from the Country Settings choose United States.
Change your address to an address in the United States.
Register for the credit card details, your address don’t have to be an US one.

So it looks like you should be able to download the Kindle for (your device) app and then download the book albeit with a bit of messing around.
Or ask your friend who downloads films etc because they will be up to speed with IP blockers, VPN (Virtual Private Networks), proxy servers and all sorts of such things that are as interesting to me as pushing pins into my eyes. OK slight overstatement there but you get my meaning...
Hey if anybody in NZ sorts it, please let others know exactly how you did it.
