Club rugby is a large part of Wellington rugby. 18 clubs currently comprise the Wellington union and all contribute at least one team to the club competitions. The premier trophy in Wellington club rugby is the
Jubilee Cup, which was won in 2012 by Marist St Pat's. Petone are the club with the most Jubilee Cup successes having won the title 22 times. Years in parentheses are when the current club was formed, though many are amalgamations of previously extant clubs. For example, Oriental-Rongotai claim their heritage back to the formation of the Oriental club in 1888 even though the current club was formed in 1969. Wellington FC is New Zealand's oldest continuous club. • Avalon RFC (1980) (Lower Hutt) •
