"Luke is a fine sculler, but will have to adapt to a sweeping role in the four. Sculling blades are a bit small and are pulled out of the water slightly differently. I'm confident he will adapt well though," Weenick said.
Watts represented New Zealand at the World University Games in Kazan, Russia, in 2012 finishing second in the B final of the single sculls after a fourth in the A final.
He was the youngest and lightest rower at the world university championships and ended up eighth overall.
Pawson was in the AWRC men's club eight crew that won silver at the North Island championships at the Bankstream NZ Rowing Championships in February on Lake Karapiro.
Watts and Pawson will be joined in the men's lightweight four by Matthew Cole from Lincoln University and Jake Guy from Auckland University.
