The Canaries established a 2-1 lead with goals from Robert Snodgrass and Michael Turner, only for Luke Moore to snatch a point with 15 minutes remaining of an entertaining match notable for both teams' madcap defending.
It was the hosts' fifth draw in their last six home matches, leaving them only five points above the bottom three with six games remaining.
"We wanted a win but nothing changes, we still have to get enough points from the six remaining matches to make sure we're secure," Hughton said.
"But all the teams around us are capable of winning games so we need to make sure we get enough points from the last games to make sure we're ok.
"We're at the part of the season that makes everyone that bit anxious and you have to have belief in the players."
