Electricity and water
Electricity is supplied throughout New Zealand at 230/240 volts, 50 hertz. Most hotels provide 110 volt AC sockets (rated at 20 watts) for electric razors only.
For all other equipment, an adapter or converter is necessary, unless the item has a multi-voltage option. Please note that power outlets only accept flat 3- or 2-pin plugs, depending on whether an earth connection is fitted.
It is safe to drink tap water in New Zealand.
