New Zealand have dropped to an all-time low of fifth in the world rankings after losing to South Africa in their Rugby Championship opener on Saturday.
The All Blacks started the defence of their title with a 26-10 defeat at the hands of the world champions at Mbombela Stadium.
It was a third consecutive loss for New Zealand, representing their worst run since they were beaten five times in a row back in 1998.
The Springboks piled more pressure on under-fire All Blacks head coach Steve Foster, who vowed to fight on after a first ever home series loss to Ireland.
Another setback in Nelspruit has dropped New Zealand below England just over a year before the Rugby World Cup starts in France.
It is now five defeats in six Tests for the All Blacks, who face South Africa once again at Ellis Park this weekend with Foster’s job seemingly on the line.
Ireland are top of the rankings ahead of France, with the Springboks third.
