David Cotterill had fired Blues into a tenth minute lead against Chris Powell's side but poor defending allowed the visitors to equalise and take a point from the game at St Andrews.
"You could see that Huddersfield were very keen to block the game and work incredibly hard to stop us playing after losing three games on the spin," Rowett said after the match.
"That was evident and it is testament as teams make it difficult for us to play our normal game.
"We moved the ball too slowly and that was the frustration.
"We scored a well worked goal and it was great to see David Cotterill on the goal sheet after five games without scoring.
"Then we concede from a long throw-in that bounces in the six-yard box. We have two chances to clear and they end up equalising. That was frustrating for me.
"Later we had moments when we should have done better.
"It was a battling performance when we didn't quite reach the heights of previous games.
"It is another game undefeated. It is another point so again we are not going to be too greedy.
"We have only lost five in 23 league games and we have to be pleased with that record."
