Marshall played the last of his 44 matches for the Hurricanes when the club won its first Super Rugby title in 2016 before he headed to the United Kingdom to link up with London Irish.
The 29-year-old joins loose forward Reed Prinsep and prop Alex Fidow in signing on for the 2019 season.
"I'm very excited to be heading back to the Hurricanes, a team that I've always loved and supported since I was a kid," Marshall said.
"I feel that it's the best environment for me to play to my potential being surrounded by the quality players and management that they have."
