Foster had his own thread for this (here), seems only fair to have one for the messiah.

Heaviest defeat in All Blacks history
Lost 43–10 to South Africa in Wellington (33-point margin). This is the largest margin of defeat ever for New Zealand in, surpassing previous highs like the 35-point loss to South Africa in 1921 or the 28-point loss to Australia in 2003.

First-ever loss to Argentina on Argentine soil
Lost 29–23 to Argentina in Buenos Aires. Prior to this, the All Blacks were unbeaten in 18 Tests in Argentina (dating back to 1985), with all previous losses to the Pumas occurring on New Zealand soil (e.g., 2022 and 2024 in Christchurch and Wellington).

First back-to-back losses to Argentina in All Blacks history
Following the 38–30 home loss to Argentina on August 10, 2024 (in Wellington), the 29–23 defeat in Buenos Aires on August 23, 2025, marked the first time New Zealand lost consecutive Tests to the Pumas.

Lowest win percentage after first 14 Tests for any All Blacks coach in the professional era
At the end of 2024 (14 Tests: 10 wins, 4 losses), Robertson's 71.4% win rate was the weakest start since 1996—worse than predecessors like Ian Foster (78.6%), Steve Hansen (92.9%), and Graham Henry (85.7%).

Most losses in the first 19 Tests for any All Blacks coach since the 1970s
As of mid-September 2025 (after the South Africa loss), Robertson had 6 losses—tied for the most in a coach's opening 19 games since Laurie Mains (1992–1995). This climbed to 7 after the England defeat, exceeding any coach's tally in that span during the professional era.

And just some Rugby Championship highlights;

First consecutive non-winning finishes in the Rugby Championship for the All Blacks
2024 (2nd) and 2025 (2nd), marking the first time New Zealand has failed to win the title in back-to-back years since the tournament began in 2012. All prior non-1st finishes (2015: 2nd; 2019: 3rd) were isolated

Lowest points tally in a single Rugby Championship campaign for the All Blacks

2024: 3 losses (to Argentina at home, and South Africa twice away), the highest ever in the tournament's history (since 2012). Previous highs were 2 losses (e.g., 2015, 2019).
