Shortening of Wainuiomata, a tough hard-core town in Wellington, New Zealand.
Residents of Wainui are known for being relaxed about their appearance and the disproportionately large number of beneficiaries living there. It is not uncommon for young Wanuiomata residents to wander down the local mall in their pyjamas and slippers after an afternoons tagging.
Also earlier known as 'Nappy Valley', Wainuiomata was a new city of young mothers and hard-working men who liked nothing more than beer, babes, and brawling.
The main centrally located taverna was the site of many altercations between groups of citizens roughly divided into five distinct groups: Rugby players (league or union), gang members (Black Power or Mongrel Mob), Honkies (People of European descent), Hori's (Maori or indigenous peoples) and Boongas (pacific islanders). All other races had to own or operate a dairy or take-away shop else they would be run out of town.
In 1981, in the first instance of it's kind in New Zealand, police were locked out of the central tavern by patrons involved in an all-out five-way melee.
Wainuiomata is a city-within-a-city, being 20 minutes from the nations capital, yet entirely surrounded by very large hills with only one way in and out (unless by sea). In recent years Wainui has become a more relaxed suburb, with the aging or imprisonment of most of it's progenitors. Male hairdressers and Asiatic races are now mostly safe in public daylight hours.
