Plug adapters / New Zealand
Type I · 230 V · 50 Hz
Do I need a plug adapter for New Zealand?
Yes. New Zealand uses type I sockets, and a US type A or B plug does not fit them. The supply is 230 V at 50 Hz, higher than the US 120 V.

What to pack for New Zealand
Pack a type I adapter. An adapter only changes the shape of the pins; it does nothing to the voltage. That matters in New Zealand, because the supply is 230 V. Look for "INPUT: 100–240 V" on your phone, laptop and camera chargers; nearly all made in the last decade say it, and those work with a plain adapter. A hair dryer, curling iron or electric kettle marked 120 V only will not, and a converter heavy enough to run one is bulkier than buying a cheap dual-voltage version or using the hotel's.
About type I sockets
Type I has two flat pins set in a V with an earth pin below, used in Australia and New Zealand. It does not resemble any US plug, so an adapter is unavoidable; one type I adapter covers both countries and Argentina.
Voltage and frequency in New Zealand: 230 V, 50 Hz
New Zealand runs on 230 V, nearly double the 120 V of a US outlet. Any device with "INPUT: 100–240 V" on its label, which includes nearly every phone, tablet, laptop and camera charger, adjusts automatically and needs only the plug shape sorted out. A device marked 120 V only will draw too much current and can burn out in seconds; that mostly means hair dryers, straighteners, kettles and some older electric shavers. A travel converter can run them, but a converter rated for a 1,500 W hair dryer is heavy, so a dual-voltage model is the usual answer. The 50 Hz frequency matters even less than the voltage: chargers and electronics ignore it, and only old clocks and some motors notice.
Same sockets elsewhere
China, Australia and Argentina use at least one of the same socket types as New Zealand, so one adapter covers a trip that includes them.

Frequently asked questions
What plug type does New Zealand use?
New Zealand uses type I sockets. A US type A or B plug does not fit, so you need an adapter.
What voltage is New Zealand?
New Zealand supplies 230 V at 50 Hz. Chargers marked 100–240 V handle it; single-voltage 120 V appliances do not.
Do I need a voltage converter for New Zealand?
Not for phones, laptops or cameras, whose chargers accept 100–240 V. Only a single-voltage appliance such as a 120 V hair dryer needs a converter, and a dual-voltage model is the easier fix.
Will my phone charger work in New Zealand?
Yes, provided it is marked 100–240 V, which almost every phone charger is. You still need a type I adapter for the socket.
