It didn't start as it meant to go on because England were the first No 1-ranked team and Australia also started above New Zealand.
Since then, it has been an All Black landslide apart from three brief spells when they were at No 2.
South Africa is the only other country to hold the No1 spot which they last held in 2009, when the current All Black reign began. Since taking back the top spot the All Blacks have played 90 tests, winning 82 with six defeats and two draws for a 92 percent winning record.
South Africa, England, Australia, Ireland and Wales have also moved into second spot during the All Blacks' run at the top.
All Blacks fullback Ben Smith made his debut against Italy two days after New Zealand re-gained the No1 spot in 2009, meaning the side have held the top ranking during all of his 55 test appearances
