List of Leaders of the Opposition of New Zealand by time in office

This list notes each Leader of the Opposition of the House of Representatives, the leader of the second largest faction within it a statutory title and salary, rather than the customary role as Official Opposition, in order of term length. This is based on the difference between dates; if counted by number of calendar days all the figures would be one greater.

Of the 18 Leaders of the Opposition, 6 served more than 30 days (1 month) and 5 have served less than 15 days.
