After 1984, Southern Hemisphere sides started to tour the British Isles more frequently, but to play fewer Tests on each tour, and thus there were no Grand Slam tours between 1984 and 1998. However, since 1998 Grand Slam tours have again become quite common, as the number of Tests on each tour has increased. The All Blacks' tours of 2005 and 2008 were originally planned to include only three Test matches; the late inclusion of matches against Wales and England respectively turned these into Grand Slam tours.
