Nick Walshe's side will now face South Africa in the final, a late try from the Baby Boks defeating the host nation New Zealand.
Billy Burns thrived on the surfeit of possession that he was given to work with, and the superiority up front quickly translated into a cutting edge out wide.
Great shift from all the boys tonight. Extremely excited to be in a World Cup final at Eden Park!Thanks for all the messages,One last push!- Billy Burns (@BillyBurns10) June 15, 2014
Burns opened the scoring with an early penalty, before possession through multiple phases had Ireland on the ropes and centre Harry Sloan ghosted over.
Another penalty from Burns made it a 13-0 game before Ireland, who were looking distinctly punch drunk, got the on the scoreboard with a penalty of their own.
It seemed to simply provoke the English pack into a reaction with Itoje and Hill carrying powerfully to set up Hobbs-Awojemi for the second try.
Burns then floated an absolute gem of a cross kick for Howard Packman to catch on the run before stepping his way to the line for a superb third. 27-3 before the half hour was up and the game looked over.
If there was any lingering doubt, to seemed to be quashed when a perfectly executed catch and drive from five metres out resulted in a try for hooker Tom Woostencroft. Burns added his fourth conversion of the evening.
Packman dropped a goal to extend the lead before a neat grubber from Ross Byrne put Gary Ringrose in for Ireland's first try of the afternoon.
Again England responded in style. Another catch and drive was superbly set up and, on this occasion, Gus Jones touched down.
Amidst a flurry of replacements from both sides, there was a late consolation for Ireland from Alex Wooton but it was too little, too late as England marched into Friday's final at Eden Park.
