what is the difference between iwi and hapu
Hapū The word hapū literally means "pregnant";[8] the usage in a socio-political context expresses a metaphor for the genealogical connection that unites the members of the hapū. (Similarly, the Māori word for land, whenua, can also mean "placenta", metaphorically indicating the connection between the people and the land, and the word iwi, for a Māori tribal group, can also mean "bones", indicating a link to ancient ancestors.)
