The world champions moved to 95.52 rankings points following Sunday's 25-24 win over the Springboks in Cape Town.
England sit in second spot on 90.14 but don't have a chance close the gap until they face 10th ranked Argentina next month.
Australia were the big movers in the latest rankings, leapfrogging South Africa and Ireland to go into third. Ireland slipped down to fourth and South Africa dropped one place to fifth.
The All Blacks moved to number one on November 16, 2009, taking the spot from the Springboks after South Africa beat New Zealand three straight times earlier that season.
Over the near eight year reign the All Blacks have claimed two World Cup titles and played 106 tests, losing just eight with three draws. During that run the All Blacks have a staggering points differential of +2091 and average 4.4 tries a game.
The rugby ranking system was brought in by World Rugby just before the 2003 World Cup. Since then the All Blacks have held the top spot for more than 12 years.
It didn't start as it meant to go on because England was 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.
The All Blacks play Australia in the third Bledisloe Cup clash next weekend and open their end of year tour against the Barbarians on November 5.
