The All Blacks and Highlanders prop married long-time girlfriend Claudia Hutton in Queenstown at the weekend.
"The de Groots" was the simple message as the pair shared their first photo as a married couple from Jack’s Point on Instagram.
De Groot was resplendent in a sharp tuxedo, his bride wore a flowing veil, and the couple were accompanied by the rugby star’s beloved golden lab, Vinny.
Among the guests was Highlanders No 8 Hugh Renton, who posted about the "unreal day".
All Blacks forwards Ardie Savea and Tamaiti Williams also sent messages of congratulations, while former Highlanders first five Rhys Patchell posted "llongyfarchiadau" — Welsh for congratulations.
De Groot will get another week to celebrate his nuptials before rejoining his team-mates for the Super Rugby Pacific season.
