Just in case anybody's missed it, in my opinion by far the best SatNav package is now available for NZ.
Even better (for UK users) maps on the TomTom website are half price until 31 Jan (so hurry if you want them).
That means NZ is £60 or so, still expensive but not the eye-watering £120!
You can get the whole of North America for £35 at the moment - I guess the sign of much greater competition in that market.
