[3] While some people thought they were no different from commonly found "tired all the time" cases, Dr Snow was convinced that they were indeed sick and proceeded to investigate.

Observing a similarity between the symptoms of stock suffering from selenium deficiency and these patients, he was the first doctor in New Zealand to identify the disease which turned out to be an outbreak of myalgic encephalomyelitis/chronic fatigue syndrome.

[1][2] Owing to, often disparaging, publicity surrounding these discoveries and a study into them by Snow, Marion Poore, and Charlotte Paul, the illness came to be known in New Zealand as "Tapanui flu" after the town of the same name in West Otago.

[3] A memorial to Snow, comprising a Moon rock and plaque, was unveiled in the main street of Tapanui on 8 August 2009.

Notable winners include Pat Farry, Tim Malloy, Graeme Fenton, Garry Nixon, and Professor Jean Ross.
