The Canaries have flown up to seventh in the Barclays Premier League after extending their unbeaten run to 10 matches with a 2-1 win over Wigan at Carrow Road on Saturday.
The club have been linked with a January move for Brighton striker Craig Mackail-Smith and midfield team-mate Liam Bridcutt.
However, Hughton wants any new player to buy into the ethos of the current squad, which has now kicked on again following the departure of former manager Paul Lambert to Aston Villa.
"Of course if you can strengthen your team you will look to do it, but it is not as easy as that," Hughton said. "We have a real competitive group and a strong squad who are all fighting.
"Sometimes players who you might think can strengthen your team, it is not the best time to do that in January. We will look at it, but if you are asking me will we definitely bring in, then I don't know."
