There were three New Zealanders in the 1912 team; Malcolm Champion, Anthony Wilding and George Hill. Wilding won a bronze medal in the men's indoor tennis singles, and Champion won a gold medal as part of the swimming relay team.
Nine athletes competed for Australasia at the 1912 Games. The team finished with six medals, two of each color, as well as one world record and an additional Olympic record at the end of the Games.
Fanny Durack and Mina Wylie, the two women who swam for Australasia, finished first and second in the only women's individual event, the 100 metres freestyle. Durack set a new Olympic record in the quarterfinals, which held throughout the rest of the competition.
The men's freestyle relay team earned the gold medal, breaking the world record of 10:26.4 (itself being newly set after the Americans broke the 10:53.4 set by the British team at the 1908 Summer Olympics) swam by the United States team in the first semifinal by swimming 12.4 seconds faster in the second final. The Australasia team dropped the world record in that event a further 2.8 seconds in the final.
Harold Hardwick and Cecil Healy each briefly took the Olympic record in the men's 400 meters freestyle heats, with the pair finishing third and fourth, respectively, in the final. Hardwick took another bronze medal in the 1500 free, while Healy took silver in the 100 free.
