Before You Travel To New Zealand
Check Passport and Visa requirements on the New Zealand Immigration website.
Electricity
The voltage in New Zealand is 230/240 volts (50Hz). If you’re bringing appliances or chargers from countries where the voltage is lower, such as the USA, Canada or Japan, check that your appliance states clearly that it is safe for use up to 240 volts.
If not, you will also need a voltage converter/transformer. If you plug a lower voltage appliance into New Zealand’s highest voltage supply, the item could be damaged.

Phone Coverage in New Zealand
Phone coverage is not guaranteed in all parts of New Zealand. Keep this in mind if you are going off the beaten track. The map below shows the general areas of 4G coverage. This may vary slightly between providers.

The Weather, Roads and Driving
The weather can be changeable. Roads can be closed for a few hours or a few days due to snow or flooding. I have been known to leave home a day early if there is a possibility the pass through the Southern Alps may be closed if I have a flight or appointment to make in Christchurch.
Drive on the left-hand side of the road. Roads in many parts of New Zealand can be narrow and twisting, more so than in other parts of the world.
The New Zealand Transport Agency has a great tool for checking for road closures and major road works.
Walking the Trails in New Zealand
There are all levels of trails in New Zealand. From simple and easy 10-minute strolls to multi-day, pack-on-back difficult/hazardous terrain trails. Pick one that is right for your level of fitness and ability.
The Department of Conservation is a great place to start planning your trips. They have good Downloadable maps of many areas showing trails and some points of interest.
