Marshall takes over the captaincy from the injured Dallin Watene-Zelezniak, who will miss the upcoming Test campaign against Australia and Great Britain following knee surgery.
The halfback will captain the Kiwis in a record 20th Test as skipper in Friday night's Oceania Cup match against the Kangaroos at WIN Stadium in Wollongong.
Marshall and the Kiwis will then return to New Zealand for matches against the Great Britain Lions in Auckland on November 2 and Christchurch on November 9.
