Make the most of your stay in the Cook Islands by being aware of the 'essentials' before you arrive.
Voltage is 220 AC/50 cycle, the same as New Zealand and Australia and the same three blade plugs (type I plug) are used. If you are traveling from a part of the world where your appliances are 110v you will need a voltage transformer. Check your specific appliances though - some can handle a range of voltages. Many of the hotels have at least one 110v 'plug' in their rooms, often in the bathroom.
On Rarotonga, Aitutaki and Atiu electricity is available 24 hours. On the outer islands it is more limited.
Electricity is relatively expensive in the Cook Islands so remember to turn off lights and appliances when you aren't using them.
