Veteran Chiefs back Charlie Ngatai will lead the team in his final season before taking up a two-year deal with French club Lyon.
Ngatai, who has been with the Hamilton-based club since 2013, was named as co-captain alongside loose forward Sam Cane for the team's 2018 Super Rugby campaign.
Ngatai, 27, has captained Colin Cooper-coached sides in the past, leading Taranaki at provincial level as well as the Maori All Blacks.
Cane, 26, has been part of the Chiefs' leadership group for years, heading into his third campaign as co-captain.
