McKenzie went over for a score of his own early in the second half with Australia continuing to demonstrate alarming fragility in defence and when Beauden Barrett converted Ben Smith's 48th-minute try, the score read 54-6 in favour of the visitors.
The New Zealand Herald reported on Saturday there were with fresh revelations suggesting the All Blacks management knew Smith's behaviour was not a one-off.
The late rally merely masked the deficiencies after the Wallabies' haphazard first-half attack included a forward pass from playmaker Bernard Foley as well as an intercept that led to a try after he tried to transfer a bad ball.
Australian rugby legend Michael Lynagh has savaged the Wallabies' "schoolboy" skills and revealed how his offers to help have fallen on deaf ears.

The Wallabies hoped to bring some solace to fans who have begun to turn away from the sport because of administrative issues and poor on-field performance.
New Zealand Rugby (NZR) confirmed in a statement that Kaino had returned home after the Daily Telegraph newspaper in Sydney claimed Kaino was having an affair with a 24-year-old Canberra model.
But the All Blacks again found a way through the Australian defence when left-winger Ioane got on the outside of floundering Israel Folau to score for a 12-6 lead midway through the half. Within minutes of the restart, Damian McKenzie scored on after escaping on the right-hand side, before Aaron Smith added an eighth score in the 47th minute.

The world champions extinguished any chance of an upset with three tries in seven first-half minutes.
With a stunned Sydney crowd on hand and the game gone, New Zealand sights turned to record scorelines.
"It showed the quality of the Aussie side in the second half to come back there and perhaps we just took the foot off the throat there". "It's not often you come here and put 50 points on the Wallabies".
A veteran of 81-Tests for New Zealand and the incumbent in the No. 6 jersey, Kaino was curiously dropped for the opening Bledisloe Cup Test in Sydney Saturday night in favour of Liam Squire. He said he wasn't going to make many changes.
"We've got to acknowledge what we did wrong first of all and then say, 'OK, we've got to fix that thing or those two things or whatever they might be, ' and then go to it and do it".
"It's nice to play in when it's coming off like that", he said.
"I've seen it over this first month that they've been together and this is a roadblock in front of us, of course, and it's going to knock us down but it's not going to stop us".More news: Gorka denies dismissing Tillerson's role on North Korea
