Funny you should mention about the paper in passports. We were looking at Will's passport the other night and we thought we could see some strangely wavy lines that appeared and disappeared. I went and dug out my uv long wave torch that I use for grading the fluorescence in diamonds and low and behold, not only did the wavy lines show up but there are hidden flecks like you find in japanese papers, all the way throughout the passport as well as a hidden number just above where they put your photo.

Just got txt from home (his day off) to say my passport is ready to pick up too. By the time you read this you'll have been to NZ and had a bloody good time :)
