La Rochelle, with former All Black Victor Vito to the fore, are further advancing their French Top 14 claims, after defeating champions Racing-Metro 38-15 in Paris on the weekend.
Vito scored a try from No 8, while fellow former Hurricane Jason Eaton was in the No 7 jersey. Former Waikato hooker Hikairo Forbes played off the bench.
Dan Carter kicked a conversion in his first game back from injury and his drink-driving incident, but it was not a happy homecoming for the 35-year-old, as some of the crowd at Stade Yves du Manoir booed him. Ben Tameifuna and Joe Rokocoko also appeared for the Parisians.
Toulouse suffered a 21-19 reverse at Brive. Joe Tekori was lock for Les Toulousains, while Luke McAlister entered the fray off the pine.
Simon Hickey kicked six goals for Bordeaux-Begles in their 46-14 victory over Grenoble. Luke Braid, Hugh Chalmers and Jayden Spence all featured for the victors, while Grenoble fielded Rory Grice and Sona Taumalolo.
