Rāhui
Māori term: the ritual and temporary prohibition that suspends access to a place or the use of a resource. According to Hirini Moko Mead, *rāhui* is fundamentally a way to halt—or prevent—a specific human activity; it can target a group or a single person, be marked by a planted post, and be lifted by an announcement or a ritual gesture. The most common forms are the *rāhui* for drowning, which protects a place where someone has drowned, and the *rāhui* for conservation, which allows a resource to replenish—both often overlap. *Rāhui* is neither an arbitrary taboo nor a mere top-down nature reserve: it is a targeted response to a specific event, lifted as soon as balance is restored.
Basically, the rāhui is a means of prohibiting a specific human activity from occurring, or from continuing.
Hirini Moko Mead classifies rāhui among the tikanga of ritual prohibition, alongside aukati, the line that must not be crossed. His definition is concise: « Basically, the rāhui is a means of prohibiting a specific human activity from occurring, or from continuing »—in essence, rāhui is a way to halt or prevent a particular human activity. It may apply to an entire group or a single person; a planted post (whakatū, “to make stand”) sometimes marks its beginning, while a ceremony or a simple announcement signals its end—or, more often, the acknowledgment that the agreed-upon period has elapsed.
Mead identifies two dominant forms, often intertwined. The rāhui of drowning targets a place where water or land has been touched by the tapu of death: the sea off Tauranga, he writes, was closed to fishing for kilometers after the drowning of Muriwai’s twin sons. The rāhui of conservation, meanwhile, suspends harvesting—shellfish, fish, timber—until a resource recovers. The two reinforce each other: death demands respect, and respect safeguards what sustains.
Rāhui is neither the folkloric “taboo” of traveler’s tales—a senseless ban defied for thrills—nor the Western nature reserve, imposed by an external authority with no connection to lived experience. It arises from a precise, dated event, often tragic, and expires with it. Its kinship with tapu is direct: it is the same sacred-prohibition activated temporarily over a place or activity—where tapu describes a permanent state of beings and places, rāhui is its time-bound application, enacted by those with the authority to impose it, and lifted once the danger or mourning has passed.
