Harvey, 32, made headlines and attracted criticism when he went on radio in the aftermath of the 87-point drubbing and said the pair needed to take their games to the next level if the Kangaroos were to achieve success.
The Roos' veteran will choose his words more carefully in the future, but the message will remain the same.
"I certainly wouldn't individualise, [but] I won't shy away from what I said because that's what I said and I still feel that now," Harvey said from Etihad Stadium on Thursday.
"For us to go anywhere we need our young guys to really stand up, but I wouldn't have mentioned their names [in hindsight].
"I've spoken to the boys, I've spoken to the coach and I've spoken to the entire group, [but] I reckon there was a little bit of an over-reaction to it.
"As long as those boys know what I was talking about then I'm happy with everything I said."
While Harvey was dismayed by the heated reaction to his comments in the media, he is at least able to see the lighter side of the situation three weeks on.
"There hasn't been much fallout other than Lachie and Sammy won't kick me the ball now," he said, tongue firmly in cheek.
"I don't have a good relationship with the coach any more and I train by myself. Other than that there's been nothing.
"But seriously, as long as the boys knew what I was talking about in-house I don't really care what other people think."
North has endured a torrid opening to the season and remains winless after suffering losses to West Coast and Fremantle as well as the Pies.
The Kangaroos play Richmond at Etihad Stadium in the only game scheduled for Easter Sunday and Harvey said he and his teammates were looking forward to moving past the indifferent start.
"It's been a tough month - I won't lie to you," he said.
"We've been to Perth twice and played Collingwood … but we get another opportunity in the next couple of days to rectify that.
"This week will be a huge test for us. We've watched Richmond's games and they're going OK as well."
Rookie Majak Daw is unlikely to earn a call-up for the match despite his recent wonder goal in the VFL that attracted so much attention, but Harvey is buoyed by the rate at which the Sudanese sensation is learning his craft.
"If you had of asked me [where he was in his football development] 12 months ago I would have said 'Absolutely nowhere', but the improvement in Majak this year has been sensational," he said.
"Some of the classy things he can do [are great] … but he's still got a little way to go. He's certainly improved and I'm hoping that he keeps improving. If he gets a game this year it will be because he's earned it."
