The Canadian wing was back in try-scoring form after an injury lay-off and a four-match drought.
DTH said: "I can't remember the last time I scored. It is great to be back playing and scoring. With all the competition we have here now and four games without scoring, you fear you will lose your spot in the team. I was thankful the coaches showed faith in me and happy it paid off."
DTH's try count for the season has risen to seven, and a total of twenty-five since joining the Warriors.
