In the First Test he overtook Wally Hammond's record of 7,249 runs to become the most prolific Test batsmen, a record he held for a year when it was overtaken by Gary Sobers. Cowdrey made only 1 run in the inaugural One Day International at Melbourne and was dropped for the Fourth Test, had his cap stolen while fielding in the Fifth Test and was dropped again for the Sixth and Seventh Tests. Illingworth won an argumentative series 2–0 and regained the Ashes, but Cowdrey only made 82 runs (20.50) in the series. They carried on to New Zealand, Cowdrey missed the First Test and needed a runner to make 54 and 45 in the Second Test at Auckland, coming in at 63/4 in the second innings when New Zealand had a real chance of winning their first victory against England, but he added 76 with Alan Knott (96), and the danger was averted.
