He was a former provincial rugby lock and an opening batsman in provincial cricket, and prior to working in radio was a physical education teacher at Auckland Grammar School (working with Graham Henry), and later became deputy principal of Takapuna Grammar School. As well as radio he hosts an aptly titled television show on Sky Sport "Deaker on Sport". Murray's trademarks are his straight-talking and his love of Biomag. His bald head has become a cult symbol in New Zealand popular culture, fondly parodied in shows such as TVNZ's Facelift.
Deaker has conducted a number of high profile interviews, including the last interview with Tiger Woods before his tabloid controversies of 2009. Deaker fell into his own bunker of controversy in 2011, with a racially sensitive slur in reference to a colleague. Despite the NZ Race Relations Commissioner describing the turn of phrase as "Not appropriate" and a weight of public outrage reminiscent of fellow broadcaster Paul Holmes' "Cheaky Darkie" saga and Paul Henry's derogatory comment about an Indian Diplomat with the surname "Dikshit", Deaker's network described the phrase as "widely used". Deaker later apologised, stating "It was a bad choice of words and I apologise unreservedly".
