Just four players who started in the Maori All Blacks' 32-10 loss to the British and Irish Lions in Hamilton in June have been included. They are captain Ash Dixon, lock Tom Franklin, No8 Akira Ioane and midfield back Charlie Ngatai.
McMillan is blessed with midfield back options, having named five such players with Super Rugby experience. However, the only outside back specialist is Manawatu flyer Ambrose Curtis.
Those selected for the first time are props Ross Wright and Tyrel Lomax, hooker Liam Polwart, locks Jackson Hemopo and Keepa Mewett, loose forwards Sam Henwood and Jordan Manihera, halfback Jonathan Ruru, first five-eighth Jackson Garden-Bachop and midfield back Teihorangi Walden.
Interest will surround the form of former Melbourne Rebels front-rower Lomax, the son of former Kiwis league prop John Lomax. The 21-year-old has committed to New Zealand by signing a two-year contract with the Highlanders and Tasman.
McMillan said most of his squad have displayed strong NPC form but admits they will lean on the experience of a handful of players to show the way.
"We are fortunate to have Ash Dixon return as captain; he is the heart of our pack and his leadership, both on and off the field, steers the team's special character," he said.
