Using a USA Prusa MK3 in New Zeland
I purchased an MK3 in 2018 for use in the USA. I sold it to a friend last week. They are going to move to New Zealand in a few months. Do they need to replace the power supply? Or will a universal power adapter work?

Safest bet would probably be to ask Prusa.
The PSU seems to be rated to handle New Zealand's 230V and 50mhz and I can only find one PSU on their site. Which could be that I'm region locked and just can't see the PSU's for other markets.

"The PSU is designed to work worldwide and automatically switch to the local voltage."
New Zealend uses 230V 50hz, You may need a new power cable with the local plug.
Cheerio,

Thank you. Also confirmed with Prusa support. Nice feature to have.

Cheerio,
I can 100% confirm your message as this is how I solved the problem with the power supply unit

Most of today's off-the-shelf power supplies, as in those in most 3d printers, use switching regulators which regulate the voltage by varying the duty cycle of the regulator device and can compensate for line voltage differences as well as varying load levels.
They don't even need to 'automatically change' between 115/120 and 230/240. They just go with the flow, so to speak.
Before I retired we had one project that needed to be used in various countries, mostly 120/60Hz and 230/50HZ but some oddballs such as Jamaica which was 115/50Hz. We tested some sample power supplies under load, and they would usually hold the output voltage constant from maybe 80 volts or so input all the way up to 250 or so, which was as high as our variable transformer could go.
You still do see some devices which will have an input voltage selector, but those are becoming uncommon.
