Can I Use My Hair Straightener (Flat Iron) in New Zealand?

Q: What plug type does New Zealand use?

New Zealand uses Type I sockets at 230V / 50Hz.

Based on what's typical for this device — confirm on the label to be sure.

Typical profile: Your hair straightener (flat iron) needs a converter and an adapter in New Zealand.

Why

The device profile's voltage and plug differ from the destination. Do not plug in with only a plug adapter: it cannot change voltage. A converter and a plug adapter that preserves any required grounding may be an option only after checking your actual INPUT label, load type, startup demand, frequency and both manufacturers' instructions. Wattage alone cannot establish compatibility; the wrong setup can damage the device or cause a fire. The cited Conair manuals describe 120V/60Hz and automatically adjusting 120/240V, 50/60Hz models. Do not broaden those ratings to 100–240V. Check your exact model and any converter prohibition; a plug adapter cannot correct an incompatible electrical supply.

New Zealand runs 230⁠V / 50⁠Hz. New Zealand runs 230V at 50Hz with the Type I plug, the same as Australia. One Type I adapter covers both countries.

Conair: CS4VCSR/CS19VCSR dual-voltage flat iron instructions: PDF p1, Operating Instructions / Dual Voltage: automatic 120/240 V AC, 50/60 Hz, correctly configured plug adapter. Preserve literal manufacturer rating; it does not establish 100 V support.
Conair: CS29N single-voltage flat iron instructions: PDF p1, Operating Instructions / safety item 16: 120 V AC, 60 Hz; no voltage converter.

Look for "INPUT 100-240V" on the label. If it shows one voltage only, size any converter from the wattage before buying.
