Hey down there, when I was on my GS in New Zealand I soon realized that Kiwis like it to have special letterboxes. I always took pictures when I saw one...Back home in Germany I created a poster with all the letterboxes I took pictures from. It's on the wall in my living-room now - as a reminder to New Zealand: 
If anybody is interested to have it as a poster as well - just send me a message and I'll send you the fileBest wishes from Gerrmanybernd
