Tapanui Flu is a colloquial and outdated name used in New Zealand for myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), coined after an outbreak occurred in the Tapanui area in the early 1980s. Though sometimes still used informally, it has been replaced in the medical community with the terms: myalgic encephalomyelitis (ME), postviral fatigue syndrome (PVFS), Chronic Fatigue Immune Dysfunction Syndrome (CFIDS) and/or chronic fatigue syndrome (CFS).
The term, Tapanui Flu, originated from a 1984 outbreak in the small, rural town of Tapanui, in West Otago in New Zealand's South Island, close to the boundary with Southland region. The late Tapanui GP Peter Snow was instrumental in identifying this outbreak.

myalgic encephalomyelitis (ME) - A disease often marked by neurological symptoms, but fatigue is sometimes a symptom as well. Some diagnostic criteria distinguish it from chronic fatigue syndrome, while other diagnostic criteria consider it to be a synonym for chronic fatigue syndrome. A defining characteristic of ME is post-exertional malaise (PEM), or post-exertional neuroimmune exhaustion (PENE), which is a notable exacerbation of symptoms brought on by small exertions. PEM can last for days or weeks. Symptoms can include cognitive impairments, muscle pain (myalgia), trouble remaining upright (orthostatic intolerance), sleep abnormalities, and gastro-intestinal impairments, among others. An estimated 25% of those suffering from ME are housebound or bedbound. The World Health Organization (WHO) classifies ME as a neurological disease.
Chronic Fatigue and Immune Dysfunction Syndrome (CFIDS) - Chronic Fatigue and Immune Dysfunction Syndrome is another term for Chronic Fatigue Syndrome, but one which emphasizes the immunological aspects of the disease. Popular in the 1990's, this term has apparently fallen into disuse.
chronic fatigue syndrome (CFS) - A fatigue-based illness. The term CFS was invented invented by the U.S. Centers for Disease Control as an replacement for myalgic encephalomyelitis (ME). Some view CFS as a neurological disease, others use the term for any unexplained long-term fatigue. Sometimes used as a the term as a synonym of myalgic encephalomyelitis, despite the different diagnostic criteria.
