New Zealand put one hand on the Rugby Championship trophy with a dominant 40-14 victory over Australia in Auckland, leaving South Africa requiring a 40-point win later on Saturday to take the title.
The All Blacks never looked likely to give South Africa hope after Will Jordan raced home for the first try 23 minutes in, with Australia's ill-discipline costing them as the hosts went in search of a bonus-point victory.
New Zealand added a penalty try and then three second-half tries to wrap up an emphatic win over their Bledisloe Cup rivals, and simply require Argentina to avoid a mammoth defeat to the Springboks to retain their crown.
Australia were temporarily reduced to 14 men through Jed Holloway's yellow card just two minutes in, but New Zealand did not get off the mark until the Wallabies were back at full strength, with Richie Mo'unga kicking a 20th-minute penalty.
The All Blacks finally clinched the first try of the contest shortly afterwards when Jordan powered home after the ball was worked to the right, before Mo'unga added the extras.
Things quickly went from bad to worse for the disjointed Wallabies, with the All Blacks handed a penalty try and Dave Porecki being yellow carded after a collapsed maul 27 minutes in.
Although the Wallabies avoided further concessions to go into half-time 17-0 down, the All Blacks stretched their lead when Sam Whitelock went over three minutes after the interval, with a video review sticking with the on-field decision to award the try.
Mo'unga then added another penalty and, as the All Blacks looked to wrap up the all-important bonus point, a well-worked maul then saw Codie Taylor fall over the line as the hosts went 32-0 ahead.
Australia added two consolation scores through Folau Fainga'a and Jordan Petaia either side of Samisoni Taukei'aho going over, but the All Blacks richly deserved their margin of victory, which makes them favourites to lift the trophy.
Resurgent New Zealand on the brink
New Zealand are on the brink of another Rugby Championship title, which would represent a remarkable turnaround for an All Blacks team which came under huge pressure at the start of the campaign.
Ian Foster's men have now won four of their last five Tests after winning just one of their previous six.
If they clinch the title, this would be their sixth success in the last seven years - only South Africa in 2019 have denied them in that span.
Home comforts reign for All Blacks
Australia struggled from the off, producing a flat display, and have now lost three Tests in a row in the Rugby Championship for the first time since September 2013.
Meanwhile, New Zealand have posted five consecutive wins over Australia and have won each of the last 23 Tests between the teams in Auckland. The last time Australia got the better of their neighbours in that city was in 1986.
