New Zealand cities and towns have excellent water supplies and in all cases tap water is fresh and safe to drink. Water from rivers and lakes should be boiled, chemically treated or filtered before drinking to avoid stomach upsets. Please note that power outlets only accept flat three or two-pin plugs, depending on whether an earth connection is fitted. The main international companies such as Avis, Hertz and Budget operate in New Zealand. There are also local rental companies such as Maui Rentals.
International airports are at Auckland, Wellington and Christchurch.
There are also direct links between Australia and Hamilton, Palmerston North and Queenstown. Tracks such as the Abel Tasman, Heaphy and Queen Charlotte Sounds Walkway located at the top of the South Island can be walked all year round. However, those tracks at higher altitudes such as the world famous Milford Track, Kepler and Routeburn are closed in the winter due to snow. You must book the Milford and Routeburn tracks between October and April. If you like hot showers and other home comforts, you should book a guided walk.
