A robust and powerful flanker, Doug Tietjens is a proud Manawatu man. HIs clinical defensive work was only matched by his uncanny ability to find the try line. 40 games at the Turbos and saw a Highlanders in 2012. Due to a serious knee injury, he only appeared 6 times for the southerners in what would be his only showing in Super Rugby after having his career cut short through injury.
