Mihimihi is the processes of formal communication as defined by Maori tikanga (custom).
Mihimihi prescribes the order in which speeches are delivered, as well as their content.
As such it defines protocol during a gathering or meeting, thus creating order and allowing all to speak and/or to be represented.
In clinical terms, this translates to a respectful exchange between clinician and service recipient/whanau.
Both have an obligation to allow the other party to speak, to actively listen and to respond in a way that fosters a sense of mutual respect and understanding.
It also relates to the clinical protocols followed by professionals, which in a mental health setting should be orderly and deliberate, and involve feedback and shared responsibility for decisions and informed consent.
