 In 1978 , Graham <unk> captained New Zealand to their first Grand Slam , including a 13 – 12 victory over Wales . That game generated controversy after New Zealand won as the result of a late penalty . Lock Andy Haden had dived out of a line @-@ out in an attempt to earn a penalty , but referee Roger <unk> insisted the penalty was against Welsh lock Geoff Wheel for jumping off the shoulder of Frank Oliver . New Zealand 's only loss on the tour was the famous 12 – 0 defeat by Irish province Munster at Thomond Park . Later a play which focused on the loss was written by John Breen , called Alone it Stands .
