With Wairarapa United playing at Central League level, a tier above Marist, who are in the Lotto Federation Cup, there is no question which side will be match favourites.
Keinzley pointed out, though, that Marist were in the Central League only two years ago and now were well on the way to recapturing that status.
In the Lotto Federation Cup, which involves clubs from Manawatu, Wanganui, Hawke's Bay and Taranaki, Marist have a four-point lead at the top of the table, winning eight of their nine games.
Winning that competition would earn them a play-off with the top side in the Capital premier division for the right to contest the Central League.
"I don't know a lot about them but they have the form on the board to suggest they will give us a tough game," Keinzley said. "I guess it's one of those banana-skin type of games, you are expected to win but you know the opposition are good enough to knock you off."
