Electrical Equipment
The New Zealand electricity supply is 240 volts, 50 hertz. Your electrical equipment should work here if you come from The UK, continental Europe, South Africa, South Korea, India, China, Russia or Malaysia.
You will usually need to fit new plugs to your equipment because New Zealand plugs are most likely shaped differently from those in your country.
A good tip is to bring 4-socket extension boards and fit a New Zealand plug to each board. In this way, you will be saved from putting new plugs on irons, kettles, toasters, computers, Hi-Fi's, etc. Keep the old plugs on them and plug them into the extension board.
If you come from a country with a 100 - 120 V supply, first check if any of your equipment can be switched to 240 V operation. If it cannot, it will need an electrical transformer to work in New Zealand. This is an expensive solution and, unless you are intending bringing equipment that you truly want to keep, you are probably best to sell it before you leave and replace it when you get to New Zealand.
Your electrical equipment will need to be modified if you come from The US, Canada, Japan, Taiwan and most of Latin America.
Wherever you come from, don't bring fixed-line telephones or faxes. They probably won't work here.
