Happy New year Matt,
Here is a website from a pair of your fellow Kiwis who are living your dream. Long White Cloud
I met Stephen and Paula Pepperell in the fall of 2008 when they gave a slide show at Barrington Yacht Club (Rhode Island, USA) covering the construction of their dream yacht and first half of their voyage. They are currently in Florida on their return trip to New Zealand. You can follow their progress on their sailblog
and keep inspired.
