Wayne Pivac’s side scored seven tries in a 48-7 victory over the Italians with North among the men to cross the whitewash.
North’s second-half try at the Stadio Olimpico was his 22nd in the Six Nations which equalled the Welsh tournament record of the legendary Shane Williams.
Now the focus turns to Saturday’s game with France in Paris where Wales will hope to complete a second Grand Slam in three years.
“We came with a real focus on what we had to do and what we had to deliver. The first-half performance gave us that straight away,” said North on the Italy match.
“We’ve obviously got a few little bits to work on which is always really positive going into a big game next week. To come away with the five points is exactly what we wanted.
“We left a few tries out there and there were a couple of defensive tidy ups, but as a whole the package was pretty good. To go to that next level we need to be at we’ve got to really up our game.
“The bigger picture is we’ve given ourselves an opportunity to go forward next week.
“Certainly after the autumn series there wasn’t much hype about us which is always good because we like to be underdogs.
“I think the hard work the boys put in over the autumn series and the early part of the Six Nations is really coming true now.
“We are far from the finished article as it is now, but we’ve still got to take some positives out of this performance and fully focus on next week.”

A brace from Ken Owens, plus scores from Josh Adams, Taulupe Faletau, North, Callum Sheedy and Louis Rees-Zammit secured a bonus-point win for Wales in Rome.
It means Wales have already equalled their best ever Six Nations try-scoring record with 17 touchdowns with a game to spare.
“We know what France are like physically. They attack with real flair. We know we’ve got to be on our mettle come Saturday. They are a team in great form at the moment,” said North.
“Physically and defensively they’ve come on leaps and bounds and we know in every aspect of our game we’ve got to make a step up.
“I don’t think we need to change anything. Plenty of us have been involved in Grand Slam weeks and big Test weeks. If you start trying to change it now you are in panic stations.
“We are at the pointy end of the stick now. This is what all the work comes down to and this is why we play this game.”
