Kirk played domestic rugby for Otago and Auckland, and first toured with the All Blacks in 1983. He stood out from his fellow players as "urbane, articulate and thoughtful," and when the planned 1986 All Black tour to South Africa was cancelled David and John Kirwan were the only two players to refuse to join the rebel "Cavaliers" team on moral grounds—he felt that it would give comfort to the apartheid regime. With the rebels banned from playing in the next two All Black test he captained the so-called "Baby Blacks". On the return of the rebels however, his position was uncomfortable and he was lucky to retain his place in the squad. Despite this, when original captain Andy Dalton had to withdraw with an injury, Kirk was made captain—and led New Zealand to victory over France in the 1987 Rugby World Cup Final. He was appointed a Member of the Order of the British Empire in the 1988 New Year Honours, for services to rugby.
