The 1973 Chatham Cup was the 46th annual nationwide knockout football competition in New Zealand.
Mount Wellington made up for their narrow loss in the marathon final of the 1972 Chatham Cup by inflicting a sound defeat on their neighbours from across the Waitematā Harbour.
Coach Ken Armstrong added to his impressive tally of cup victories both on and off the field.
Shore's cause was not helped when keeper Turner had to be substituted early on after an injury, but even without this handicap the Mount would have proven the stronger side.
All the goals came from Mount Wellington's players, with two from Dave Taylor and one from John Houghton.
