Colquhoun was a lower-order right-handed batsman and a useful wicketkeeper who came late to first-class cricket, not making his debut for Central Districts until he was 29. A year later, he was in the New Zealand Test team for the two matches against Len Hutton's 1954-55 England team, fresh from retaining the Ashes. England won both matches fairly comfortably and in the second, at Auckland, New Zealand were dismissed for 26, which remains the lowest-ever total by a Test match side.
Colquhoun's own distinction in this second match was to be dismissed first ball in each innings by Bob Appleyard; each time, Alex Moir, who also failed to score in either innings, prevented the hat-trick.
