New Zealand have suffered their first ever home defeat to Argentina to renew the pressure on coach Ian Foster.
The Pumas won 25-18 in Christchurch amid scenes of wild celebration to go to the top of the Rugby Championship table, having also beaten Australia a fortnight ago.
The pressure on beleaguered All Blacks coach Foster looked to have been eased when his team defeated South Africa 35-23 in Johannesburg in the last round. But now it is sure to be ratcheted up again.
