"Look, it wasn't up to our usual standards, we know that. We've spoken about the things we need to work on and hopefully we can fix that up this week."
In the Kiwis' favour is the fact they will field an unchanged starting line-up from the Whangarei match, with coach Stephen Kearney resisting the urge to make changes ahead of their final round robin game.
"That's something that's been really good," Foran said. "We haven't been hit with too many injuries, as has happened in previous tournaments, so that's a good thing. And it always adds that flow when you can keep the same team on the paddock."
Foran brushed aside concerns over his fitness, having fully recovered from a corked thigh sustained in the torrid Toll Stadium win.
"We're all right. We were a bit battered and bruised. They played a really physical game against us and we just got away with the win there.
"We rested up and got all the bumps and bruises fixed and now [we're] just focused on the game on Saturday night."
The Kiwis were finding it a bit colder down south, with Dunedin's temperatures perhaps better suited to their opposition, but Foran was confident they would adjust to the local conditions.
"It's pretty cold isn't it? A different temperature to what we are used to but it was a good training session today. Maybe they're [England] a bit more used to it than us but we'll adapt fine."
Foran revealed he was yet to receive an apology from Warriors co-owner Eric Watson for a premature tweet made on Sunday that welcomed his signing with the club.
Watson later made a second tweet apologising for the gaffe but Foran would not comment on whether the matter would affect his decision about which club he will sign with for 2016 and beyond.
"No, not yet but I haven't really read too much into it. I'm not looking into my future, in the meantime I'm just focusing on the Four Nations."
England will present another strong physical challenge for the Kiwis, with the visitors boasting a big, strong forward pack that includes the likes of South Sydney's Burgess brothers, George and Tom, however Foran was confident they could match them.
"Yeah, they're big boys aren't they? They're used to playing with one another, they're great players, they've really established themselves in the NRL and they are hard to handle.
"They are a quality side, they always have been and it will be no different this Saturday night."
England forward Tom Burgess yesterday limped out of training with what looked to be a lower leg problem.
2 ways Kiwis can make the final
If they beat England
A win over England, or a draw, will put the Kiwis through to the final at Westpac Stadium on November 15. Should the Kiwis lose to England by nine points or less they will still make the final. A nine-point loss will leave them tied with England on for-and-against but their stronger defensive record would see them advance on percentages.
If they lose...
However, if New Zealand loses by 10 points or more England will finish higher on the tournament ladder. The Kiwis would then be left hoping the Kangaroos do not make up the points differential between the two teams against Samoa.
