However, with the All Blacks being handed their first home series loss to Ireland, de Groot was re-selected for the 2022 Rugby Championship squad.

Retaining his role as the first-choice loosehead prop in 2023, de Groot was selected in Ian Foster's 33-man squad for the 2023 Rugby World Cup.

De Groot became the first New Zealand player to be given a red card in a Rugby World Cup in the pool stage of the tournament.

In this pool game against Namibia, a 71–3 win, he was initially given a yellow card for a high tackle on Adriaan Booysen, with a 'bunker' review upgrading it to a red.

[13] De Groot returned from a suspension to produce strong performances in New Zealand's quarter and semi-final fixtures against Ireland and Argentina respectively before he started in the World Cup final; an 11–12 loss to South Africa.
