Koha is an example of the reciprocity which is a common feature of much Māori tradition, and often involves the giving of gifts by visitors (manuhiri) to a host marae.
Traditionally this has often taken the form of food although taonga (treasured possessions) are also sometimes offered as koha, and in modern times money.
At hui, any money given helps with the actual costs associated with the meeting, and for the benefit of non-Māori unfamiliar with the custom some marae may suggest a particular amount to be given as koha, but it remains a freely given gift rather than a charge for services or facilities.
In New Zealand English it is becoming more frequent to refer to the small gifts, or more commonly food such as biscuits, desserts or cakes, which are presented when visiting friends or family as koha.
