OBU is one of Wellington and New Zealand's largest clubs and has a number of thriving social or non-training teams add colour and vibrancy to the club. We also have senior teams in the top 3 grades of mens rugby in the Wellington competition and other training teams such as the under 85kg teams,  age grade teams (under 19 and under 21), as well as a strong womens team. Over the summer we also have several touch teams entered in local competitions.

Over the years, the clubs combined have produced twenty-nine all blacks, including two All Black captains - George Gothard Aitken in 1921 and Stuart Sinclair Wilson in 1983. The club's most recent All Blacks have been half-back, Jon Preston, midfielder Paul Steinmetz and centre Conrad Smith.
