The 1981 Chatham Cup was the 54th annual nationwide knockout football competition in New Zealand.
Early stages of the competition were run in three regions (northern, central, and southern), with the National League teams receiving a bye until the Fourth Round of the competition. In all, 124 teams took part in the competition. Note: Different sources give different numberings for the rounds of the competition: some start round one with the beginning of the regional qualifications; others start numbering from the first national knock-out stage. The former numbering scheme is used in this article.
The major talking-point of the 1981 competition was the giant-killing run of Stop Out, who caused upsets against the higher-ranked Nelson United, Miramar Rangers and Wellington Diamond United on their way to the semi-finals.[1]
