Query: Not very useful

This book was not at all useful as a travel guide. It's not very useful as a story either. The author is self involved, self important and describes things we'd rather not know, like his sexual exploits (just look at his picture and you'll know why). He's into wine, women and cigars in a very annoying way. He complains a lot and seems to have an inability to roll with the punches. He is basically a sexist bore. Look elsewhere for a better read and info on New Zealand.
