The Christchurch-born loose forward had the game of his life against South Africa in 2015.
Leitch was arguably the best player on the park, when the 'Brave Blossoms' shocked the sporting world with a 34-32 win.
Leitch has since had a decent stint at the Chiefs, before joining the Sunwolves for the last two Super Rugby campaigns.
This will mark Leitch's third World Cup and second as captain, after Eddie Jones handed the 30-year-old the armband in 2014.
