New Zealand arrived in Dublin on Sunday looking to become the first Test team to complete a perfect calendar year.
The All Blacks dispatched England 30-22 at Twickenham to secure their 13th successive victory and have Ireland in their sights at the Aviva Stadium next weekend.
Wing Julian Savea finished man of the match in London after running in two tries to lift his tally to 18 in 19 Tests.
It was an epic contest decided by Savea's 64th-minute try as he capitalised on a moment of genius from centre Ma'a Nonu.
"There were moments when we dominated and moments when they dominated. We knew it would be a fight to the end and the boys really stepped up," Savea said.
"Under pressure we made the right decisions. We kicked well, we chased well and put the pressure back on them. We're happy we've got the win.
"England are very dangerous. They have some big boys who carry well. We respected them and they really took it to us."
Savea sat out last Saturday's victory against France with a lung infection, but earned an instant recall to the All Blacks' starting XV.
"Missing an opportunity in France motivated me. Just that black jersey, it means a lot," he said.
"There's obviously competition and we're all striving to be better.
"If one guy's playing well, we have to play better. That's how it is."
