New Zealand's electricity supply runs at 230/240 volts, and we use angled two or three pin plugs (the same as Australia).
Most hotels and motels provide 110 volt ac sockets (rated at 20 watts) for electric razors only. For all other equipment, an adapter/converter is necessary, unless the item has a multi-voltage option.
