The 1980 Chatham Cup was the 53rd annual nationwide knockout football competition in New Zealand.
The match returned to its former regular home, the Basin Reserve, for the first time since 1972.
Mount Wellington won the competition, becoming the third team to win the league/cup double.
Te match was a dour affair, with the Mount scoring both of the goals.
The first was scored after eleven minutes when a Clive Campbell corner was headed into the Dunedin goal by Stewart Carruthers — a welcome change from his sending off in the previous year's final.
