It is the premier club competition trophy of the Wellington Rugby Football Union, and the current holders are OBU, following their defeat of Tawa in the 2024 final.
The next most successful club is Marist St Pats (14 titles since formation in 1971) who can also claim another 6 titles from its predecessor clubs Marist Brothers Old Boys (3 outright, 2 shared) and St Pat's Old Boys (1 shared).
Since then the trophy has been won by Marist St Pats (7), Petone (3), Norths (3) Poneke (2), Hutt Old Boys-Marist (2), Tawa (2), Oriental-Rongotai (2), Western Suburbs (1), and Old Boys-University (1).
Norths and Marist St Pats also shared the 2008 title after the final finished 10-all and the competition rules did not allow for extra-time to be played, a situation which has since been rectified.
The Jubilee Cup is also contested in a round-robin format, this time over seven rounds, with the top 4 teams progressing to the semi-finals where the top team (since 2009 awarded the Andy Leslie Trophy) hosts the fourth-placed qualifier and second hosts third.
