What is the traditional practice of gifting pounamu (greenstone), where it is considered culturally appropriate only for the stone to be given as a gift rather than purchased for oneself?

• A Pounamu must be worn at all times
• B Pounamu can only be carved by tohunga
• C Pounamu must be given by a kaumatua
• D Pounamu should be gifted, not bought for oneself ✓

While not a universal rule, many Māori hold that pounamu carries the mana of the giver and that purchasing it for oneself lacks the spiritual significance of receiving it as a gift — a belief that has been widely adopted in broader culture.
