WHY WE EXIST
Korean engineering, distributed with care.
Onui exists because the K-beauty devices NZ customers were searching for did not have a proper local distributor. We changed that.
ENGINEERED IN KOREA
Made by people who do this all day.
We only carry products from small Korean houses with real engineering or formulation depth behind them — not white-label, not drop-ship.
BACKED IN NEW ZEALAND
Twelve-month local warranty.
You deal directly with Onui for any service, returns or replacements. No overseas shipping involved.
ONE EDITED ROUTINE
Three devices, one gel, eight minutes.
We carry the smallest set we can — what actually works as a daily routine, nothing else.

How Onui works
Curated from Korea. Backed in NZ.
Named after the Korean word for siblings (오누이), we embody the older sister side of the relationship: protective, discerning, and honest. We source directly from the makers and back every product here at home with fast local shipping, a 12-month NZ warranty, and a real person to call whenever you need support.
Our first shelf opens with DualTetra, a dual-head skincare wand from a Korean engineering house that spent years quietly perfecting the technology. The fact that each unit is individually tuned before leaving the factory tells us everything we need to know about how seriously they take their craft.
Our catalogue will always stay small by design. We only add a product after it has truly earned its space.
