New Zealand smashed Ireland by a record 60-0, with Australia narrowly beating Wales 20-19 in the final tests of their Southern Hemishpere tours.
New Zealand racked up nine tries over Ireland to help sweep their three-test series.
A brace of tries from Sonny Bill Williams and Sam Cane saw the match effectively over as New Zealand led 29-0 at half-time.
Ireland captain O'Driscoll said: "That scoreline is a bit embarrassing. We knew we had to start well and we didn't. That's what the All Blacks do when they get a 15, 20-point lead they just play their own game and you're running after them for 80 minutes."
The previous largest winning margin against Ireland was 53 points, when the All Blacks won 59-6 in 1992.
Australia claimed a 3-0 series whitewash over Wales punishing indiscipline by the Grand Slam winners.
The first half was scattered by errors with referee Craig Joubert blowing 14 penalties in the opening 40 minutes.
The Wallabies took a 12-9 half time lead.
Wales regained the lead in the 71st minute with another penalty goal but Barnes sealed victory for the Wallabies with his fifth penalty of the match to give Australia a narrow 20-19 win.
Wales caretaker coach Rob Howley said: "It has been a fantastic series and we are going to improve as a result of this. It was disappointing in the last 10 minutes after taking the lead because we didn't make the most of the opportunities we had. We have to learn from that."
