Plugs and Sockets in the Cook Islands

Didn’t pack an adaptor? You can still grab one when you arrive. Still, it’s better to bring your own than risk paying too much for something unreliable.

The Cook Islands are often visited with Niue and Fiji. Plug systems aren’t always consistent across the Pacific, so it’s worth checking in advance.

Type I sockets have two flat angled pins and sometimes a vertical earth pin. UK Type G plugs do not fit into Type I sockets.

Do You Need a Voltage Converter?

A voltage converter only helps if the supply is different. In the Cook Islands the mains voltage lines up with the UK, so there’s no need.

Always check the mains voltage label before plugging in abroad; if it shows ‘100–240 V, 50/60 Hz’, you won’t need a converter.
