The 2002 Chatham Cup was the 75th annual nationwide knockout football competition in New Zealand. Up to the last 16 of the competition, the cup was run in three regions (northern, central, and southern), with an open draw from the quarter-finals on. The competition comprised a preliminary round and four rounds proper followed by quarter-finals, semi-finals, and a final. The competition was held considerably earlier in the year than normal, with the final being held in July rather than September. In all, 136 teams took part in the competition.
