This year's end of year tour could be the last the All Blacks play in its current form.
French newspaper Midi Olympique reports from 2020, World Rugby wants to introduce a 'League of Nations' format involving the top 12 teams in the world.
The idea of World Rugby vice president Agustin Pichot reportedly sees an international competition dividing into four groups of three, with three pool games followed by a semi-final and final.
The report says the World League would be played alternately in the Northern and Southern Hemisphere each November, with the North to hold the proposed first edition in 2020.
The groups would also be held in different countries.
