Looks Like An Ideal Guide.,
This review is from: Frommer's New Zealand Day by Day (Frommer's Day by Day - Full Size) (Paperback)
Customer review from the Amazon Vine Programme (What's this?)I am off the Egypt this year but I have been looking in to going to New Zealand some time in the next couple of years.
As with any such trip it is worth spending some time and effort in researching the location and what it has to offer and this guide book appears to answer many questions relating to local customs and mains voltage which is 230v so our UK devices should work with just an adapter plug.
The guide also gives other advice such as if your visit is for a limited amount of days you may want to stick to one of the two islands rather than wasting a lot of time travelling.
It gives you lots of information on where to stay and of course where to visit plus of course outside activities available in that part of the country.
It also suggests multi day tours and has some information on hiking.
Based on how much a trip to NZ is going to cost, I think this is a small price to pay.
Enjoy the guide and enjoy your trip to New Zealand.
