Having younger players in such key positions makes Wanganui's task even more of a challenge, given South Canterbury have named their strongest and most experienced outfit.
Hawke's Bay loan fullback Liam Edwards, centre Shayne Anderson and wing Setefano Sauqaqa are confirmed in the starting lineup after injury.
Brad Hemopo was the No8 who caught Wanganui napping and snuck down the blindside from a 5m scrum to score the winning try in South Canterbury's 21-17 win between the team's in September.
The side is captained by incumbent NZ Heartland XV skipper Kieran Coll.
The TAB has literally taken a bob each way, with both team's paying $1.85 head to head.
Kickoff is 2.30pm.
