Lock Josh Lane and first-five Dane Whale are in the standby group.
New head coach Nigel Walsh, his Whanganui assistant Jason Hamlin and the selectors have chosen a side weighted towards the six teams who made trophy games this weekend, with only three players (two East Coast, one Horowhenua-Kapiti) not taking part.
After their unbeaten season to host the Meads Cup final, the highest-represented union is Walsh's own team South Canterbury with six players, while Mid Canterbury have four, Meads finalists Thames Valley two, Lochore finalists North Otago two and Poverty Bay one.
With highly physical games expected, Whanganui coach Jason Caskey hoped circumstances might yet allow Lane and Whale to pull on the black jumper.
"Hopefully, might ease them into the squad. They're both two guys that really deserve a crack at it.
"Dane's been pretty consistent for most of the year.
"It's a pity that Jamie [Hughes] didn't make it."
Hughes played his 50th game for Whanganui in the win over Thames Valley, but the selectors have gone with South Canterbury's Nick Strachan as the specialist openside flanker.
Unless Covid-19 restrictions prevent it, the squad will assemble in Tāupo on December 2 for a five-day camp.
Walsh said the build-up will have an off-field focus to allow the players to come together.
"We obviously don't have a lot of time to prepare so it'll be about building culture, morale and team atmosphere.
"Apart from that we'll focus on our connection work and getting our phase plays and structures right."
The game will be at Owen Delany Park on December 5 at 2pm, and broadcast live on Sky Sport.
