Howlett pushes right winger Isakela Nacewa to the reserve bench while Woodcock's introduction means there is no place in the 22 for loosehead prop Saimone Taumoepeau.
Halfback Steve Devine will make his first start of the competition ahead of David Gibson, as will hooker Derren Witcombe, who usurps All Blacks rake Keven Mealamu.
Ben Atiga is still sidelined with a hamstring strain, meaning usual first or second five-eighth Luke McAlister will start again at centre.
