Although New Zealand is one of the easiest countries in the Asia-Pacific region for Westerners to navigate, a little extra knowledge can still go a long way. Most of the following tips are courtesy of www.newzealand.com.
When to go
The north of New Zealand is subtropical and the south temperate. The warmest months are December, January and February, and the coldest June, July and August. In summer, the average maximum temperature ranges between 68º-86º F, and in winter between 50º-60º F.
Costs
Prices are very reasonable for such a developed, modern country. The average room rate in New Zealand hovered around $120 in 2006, and a three-course meal without wine can range anywhere from $15-$40 (prices are in USD).
Safety
The country has a relatively low crime rate and good health care. The telephone number for any emergency in New Zealand is 111. If travelers happen to be using one of the country's two main cell phone providers, they can send text message updates about their location and travel movements to 7233 [SAFE]. These details are kept on a central database that can be accessed by police if necessary.
Electricity
Electricity is supplied at 230 volts, 50 hertz. Hotels provide 110-volt, 20-watt sockets for electric razors only. Most plugs in New Zealand accept three-pin plugs or similar international adapters.
Money
New Zealand's unit of currency is the New Zealand dollar (NZ$). Foreign currency can easily be exchanged at banks, some hotels and Bureau de Change kiosks, which are found at international airports and in most city centers. All major credit cards can be used in New Zealand. Travelers checks are accepted at hotels, banks and some stores. Tipping is not obligatory.
Visas
Most visitors to New Zealand do not require visas unless they intend to work, study or seek employment. All visitors must have a current passport, valid for at least three months after the intended date of departure from New Zealand.
