Tramping the New Zealand bush (forests) can be extremely dangerous if you are not properly prepared and equipped. The weather can change without warning. If you don't have the right equipment you may die from hypothermia. [http://www.mountainsafety.org.nz/ NZ Mountain Safety Council] has some information online but it is recommended that you visit a DOC office before setting out on a trip. You should always ensure you tell someone reliable of your plans, and inform them when you return. You can do this at a DOC office.
The New Zealand bush is very dense in most places. Unless extremely experienced, you should not leave marked tracks.
In most back country areas, water can be drunk directly from streams. In some areas, such as the Mangatepopo Valley in the North Island's mountain plateau, diseases such as ''Giardia'' are present. The safest options are to use a water-purifying tablet, such as iodine, or to boil water for at least 3 minutes.
Many of the national parks have basic accommodation called huts, which range from a basic roof over your head with large bunk spaces and a "long drop" toilet, to the deluxe huts on the [[Milford Track]] with individual bunks and flush toilets (one of which has electric lighting).
There are two classes of huts. Back country huts and great walks huts. The back country huts are very basic but also very cheap. Back country huts range in price from $0 to $15 per person per night and you can get an annual back country hut pass for $65. The great walks huts range in price from $10 up to $35 per person per night.
Back country huts are often maintained by tramping clubs on a volunteer basis whereas DOC tend to maintain most of the great walks huts. Please treat the huts with respect as they are offered to enable people to access the national parks and no
-one is paid to clean up after you.
It's a good idea to sign the visitors book that you will find in most huts. If you get lost, it helps narrow down where you last were.
Some people feel inclined to bring a tent. There are tent sites in some of the low lying areas but most people will find that the hut system is roughing it enough. A tent is great if you want to camp next to your car but it's not really what you want for tramping.
New Zealand has a number of 'Great Walks', which are very well maintained, cover some of the most beautiful scenery, and in the peak season, can be quite busy, requiring bookings with DOC well in advance. More information is available at [http://www.doc.govt.nz/

New Zealand tries hard to prevent introduction of unwanted flora and fauna. Make sure you clean the mud from your boots, tents, groundsheet and stoves before you enter the country. Tramping equipment will be inspected on entry into the country. If you have any type of sports equipment in your luggage, declare it; there is a $200 instant fine for having undeclared (and dirty) equipment or sports footwear in your possession.
