The Blues followed up last week's win over the Crusaders by easing to a bonus-point 47-8 victory over Moana Pasifika at Eden Park on Saturday.
All Blacks winger Mark Telea scored a hat-trick of tries and Stephen Perofeta put 17 points on the board in a comprehensive win.
"This game wasn't going to be easy. They're a tough side, they're a lot of our brothers and we grew up playing with them, so we always knew this was going to be a tough match," Auckland back rower Akira Ioane said.
Fijian Drua overcame a first-half red card for hooker Tevita Ikanivere to notch up a third successive win at Churchill Park in difficult conditions in Lautoka on Saturday with Isaiah Armstrong-Ravula scoring 16 points in the home side's 31-13 victory over the Western Force.
Tom Horton put the visitors ahead with an early try but the Drua took control as they mastered a waterlogged pitch, with wingers Epeli Momo and Selestino Ravutaumada, and centre Iosefo Masi scoring tries.
Filipo Daugunu's last-minute try confirmed the Melbourne Rebels' 27-21 win over the New South Wales Waratahs, the winger sealing a third victory of the season for the team facing serious financial problems.
