All Black full-back Israel Dagg will start for the Magpies as they look to wrestle the Ranfurly Shield off Counties at the ECOLight Stadium in Pukekohe.
Dagg comes into the side at number fifteen after missing out on selection for New Zealand's two Rugby Championship fixtures against Australia.
He takes the place of Mikey Vuicakau, with Ryan Tongia shifting to the number eleven jersey in an otherwise unchanged starting XV from last week.
Meanwhile, the Steelers have a strong backline that includes captain Tim Nanai-Williams at full-back as Sherwin Stowers moves to the wing.
Rey Lee-lo and Bundee Aki continue their centre partnership while the eight, nine and ten axis is once again Jordan Taufua, Augustine Pulu and Ahsee Tuala as Tana Umaga's Counties look to retain the coveted Log o' Wood.
