He reported on New Zealand's tour of South Africa in 1953-54, and wrote his first book about the tour, Silver Fern on the Veld. Great Days in New Zealand Cricket followed in 1958: 26 chapters, each one describing a significant match in New Zealand cricket history. Fittingly, the longest chapter is the last one, on New Zealand's first, and at that stage only, Test victory, in Auckland in 1956. In 1961 he wrote New Zealand Cricketers, 50 chapters, each one on a prominent New Zealand player, past or present. An extra chapter at the beginning is about Lord Cobham, New Zealand's cricket-playing Governor-General, who had just played his last first-class game at the age of 51, while a postscript is dedicated to "the below average cricketer", the dedicated but ungifted club player: "Without him, the game would not survive, because it would be meaningless." Having attended first-class cricket matches in New Zealand since 1928, Brittenden had watched and in most cases known personally all 50 subjects, except for the Wellington batsman Syd Hiddleston, "and I have found many cricketers of mature years eager and willing to talk about him". He covered the tour to England, India and Pakistan in 1965 and the West Indies tour to New Zealand in 1968-69 and subsequent New Zealand tour to England, India and Pakistan in 1969-70. In 1977 he wrote The Finest Years: Twenty Years of New Zealand Cricket, covering 17 significant Test Matches beginning with the victory at Auckland in 1956 and ending with the victory over India in Wellington in 1976; 22 profiles of leading players of the period follow. Of New Zealand Test cricket he writes, "It will always be a matter of ups and downs, with such a relatively small cricket population. The fact that there are ups is sufficient encouragement." More books followed: 100 Years of Cricket: A History of the Canterbury Cricket Association, 1877-1977 ; Hadlee ; A Cricket Century: The First 100 Years of the Lancaster ParkCricket Club Inc. ; Test Series '82: The Australian Cricket Tour of New Zealand ; Big Names in New Zealand Cricket: Fifty Profiles ; The New Zealand Cricketers' Who's Who ; England Skittled: New Zealand v. England, Wellington, 10–15 February 1978.
