The 1983 Chatham Cup was the 56th annual nationwide knockout football competition in New Zealand.
Mount players Tony Sibley and Ron Armstrong joined an elite group to have played in four Chatham Cup-winning sides, having previously played in Mount Wellington's victories in 1973, 1980, and 1982.
Fred de Jong opened the scoring for the Aucklanders after 14 minutes, only for Colin Walker to equalise halfway through the first half.
In the second period Walker put the East Coasters ahead, and they held the advantage until the dying minutes when Keith Nelson, scorer of the only goal in the 1982 final, scored for the Mount to level the tie.
The Mount took the lead on the half-hour mark with a John Price penalty, and the game was put firmly out of Gisborne's reach just before the final whistle by a shot from Nelson.
