Former All Blacks players said they were "shocked" on Sunday and described Wales' performance as "heroic" after New Zealand suffered a monumental 35-28 upset in Cardiff.
The Welsh defensive display was lauded by New Zealand commentators and media after the home side clung on in the Nations Championship match to record their first success between the two sides since 1953.
Former test flyhalf Stephen Donald admitted he had given the 10th-ranked Wales little chance of ending their run of 34 successive defeats against New Zealand.
"I may have said during the week that this was going to be pretty much a training run," Donald told New Zealand broadcaster Sky TV.
"And to my surprise, the Welsh performance – no one could believe that they had that performance in them.
"I'm shocked really to be fair. You still felt that the All Blacks attack was going to be too much for them in the second half once they got going.
"But all of a sudden Wales' defence went through the roof."
Former New Zealand prop Angus Ta'avao said while hard to accept the result, it provided a much-needed shake-up at the top of the global game.
He lauded the performance of Wales, given their dire run of results over the past two years and off-field financial struggles.
"You've got to tip your hat to Wales. This is an amazing effort, a heroic effort from them," Ta'avao said.
"You see what it means to them, the tears that are on their faces.
"As gutted as we are as All Blacks fans, I think what a great occasion, what a great day for rugby and it just goes to show anyone on any day can beat another team."
Under a headline, "The upset of a generation", the New Zealand Herald described the All Blacks' performance as "clunky" and Wales' as "scarcely believable".
The Stuff news website said questions would be asked of coach Dave Rennie, who had been praised for bringing cohesion since taking over this year, despite New Zealand crashing 3-1 to South Africa in their recent four-match series.
Stuff's report said "embarrassment might rise in the cheeks of some All Blacks" when they review the loss ahead of next week's match against England in London.
