The Chappell–Hadlee Trophy in cricket is a One Day International cricket series between Australia and New Zealand. It is named after legendary cricketing families from the two countries, the Chappell brothers (Ian, Gregory, and Trevor) of Australia and Walter Hadlee and his three sons, (Barry, Dayle and Sir Richard), of New Zealand. The trophy was contested annually from 2004–05 until 2009–10 as a three- or five-match series, and as a one-match series during the World Cups in 2010–11 and 2014-15. However, the tournament is no longer an annual event.
