Blues coach Tana Umaga named an unchanged starting XV after their impressive opening round demolition of the Melbourne Rebels last Thursday.
But he's been quick to add some star power to his impact options for the juicy second round clash with the Chiefs.
Umaga has six All Blacks, a Maori All Black and a New Zealand under-20s player on his bench.
This derby is usually a high-octane affair that often goes right down to the wire. Substitutions are sure to be hugely influential.
