Authentic Ngāi Tahu pounamu prominently displays both the registered trademark and a unique traceability code. When entered online this code identifies the origin and whakapapa (genealogy) of the stone.

It will describe how it was extracted and processed and tell you who the artist was that carved it. It will explain that the stone has been treated according to the customary respect and carved with every possible care.

Only licensed individuals or businesses can use this mark. This means, provided they follow the specific rules and regulations, that these businesses can purchase raw pounamu from Ngāi Tahu for carvings.
