New Zealand competed at the 1928 Summer Olympics in Amsterdam, Netherlands with a team of ten competitors: four athletes, four swimmers and two boxers.

Porritt was at the time based in England for tertiary study and was thus in a position to arrange some things in Europe.

Porritt, a runner, was joined by eight other competitors: four swimmers, three track and field athletes, and two boxers.

[2][3] Both the boxer Alf Cleverley and the swimmer Len Moorhouse did not receive financial support by the Olympic Council for their journey to the Games, but had to pay for it themselves.

[4] A New Zealand rowing eight (including the future All Black Hubert McLean) was selected but was unable to travel to the games because of lack of funds.
