My wife was cleaning a shelf and came across a photo album of our 2009 trip to New Zealand. It is amazing what you forget. Luckily, we did a blog and can look back and recall the visit.
If you get a chance, do go. At every turn it is beautiful and the people are warm and welcoming. It is NOT like the UK. Yes, the people speak English and lots of the birds in towns are English ones, but the wild places are not the same, with wild tree ferns and many trees quite different. 4 million people instead of more than 60 million helps!
