Steven Luatua and Ben Franks are among six former All Blacks and 13 Kiwis in the team coached by Robbie Deans and Scott Robertson.
Highlanders' Luke Whitelock, Richard Buckman and Dillon Hunt were included, while other notables additions were fullback George Bridge and Auckland wing Vince Aso.
The squad already included five players - Richie Mo'unga, Dominic Bird, Hunt, Mitchell Drummond and Atu Moli - who join the All Blacks after this match on Sunday (NZT).
Leading UK and French players have largely not been released from their clubs with the match sitting outside the test match window.
Julian Savea and former Crusaders halfback Andy Ellis are joined by two of the Barbarians side that lost 31-28 to the Wallabies in Sydney last Saturday. Giant Fijian-born wing Taqele Naiyaravoro will be keen to repeat his two-try effort against the Wallabies. Likewise lock Sam Carter his strong performance.
The South African contingent includes former Springboks captain Adriaan Strauss and Stormers first five-eighth Robert du Preez, who led Western Province to last weekend's Currie Cup final victory over the Sharks.
While there are some headline acts, of the 26-man squad, 17 players are uncapped internationally.
