But Black Sticks coach Mark Hager remained wary of the opposition, despite England enduring a miserable one-win World Cup campaign last month.
"You're always wary of wounded teams," he said after watching the romp over Canada. "Their World Cup wasn't a good performance and they know that.
"They've had a change of coach for this tournament and they've been getting better and better, I've felt, each game. I thought they played really well against Australia and I don't think 3-0 was a good reflection of that game.
"We've got to be mindful of them and make sure we do our homework and give them the respect they deserve."
Hager was impressed with England's 2-1 win over Scotland earlier in the day, sealing second spot in their pool, and Forgesson was also expecting a tough encounter in the semifinal.
"We watched the game this morning and they seem to be improving as we go on, so they will be really dangerous," she said. "They're quite attacking at the moment, which is a little bit of a change from the World Cup, so we just have to be aware of that."
The Black Sticks' own attack has yet to gell, Forgesson reckoned, with their impressive offensive output skewed by the 14 they put past a hapless Trinidad & Tobago. There were positive signs in this morning's thrashing of Canada but still too many missed opportunities.
"Canada have been defending quite well so it was satisfying to score a few," Forgesson said. "We're creating lots of opportunities but we're just not quite connecting with them all, so that would be nice to tidy up."
And if the Black Sticks do manage to sweep aside England, the big one awaits on Sunday morning.
"We obviously know Aussie quite a bit, and vice versa, so we're always watching them, and they are playing quite nice hockey," Forgesson said. "They're really dangerous, so we are watching them, but we have to win the next one first."
