Crusaders coach Todd Blackadder has made seven changes to the side humbled 34-25 by the Blues at Eden Park last weekend, with the main discussion point around his decision to retain Colin Slade at fullback and shunt Dagg, the All Blacks incumbent No 15, on to the wing.
Following an indifferent performance in the Crusaders' opening loss to the Chiefs in Christchurch Dagg was dropped to the bench for the Blues match.
Dagg is no stranger to playing on the left wing for the Crusaders, having started there in the opening round loss to the Blues last year. He has also been selected on the wing for the All Blacks.
Johnny McNicholl has been added to the right wing and Rob Thompson has dropped right out of the 23. Blackadder has resisted chopping-up his midfield by retaining Ryan Crotty and Lee-Lo. Tom Taylor is again at flyhalf.With Richie McCaw gone for two months with a fractured thumb, Matt Todd gets his first start of the year at No 7.
Luke Romano replaces fellow All Blacks lock Dominic Bird and Wyatt Crockett comes in for loosehead prop Tim Perry.
