"We've got a challenge on Saturday, and the boys will be up for it," said coach Mark Cosford.
"Since Russell Gedye and I started coaching them, we haven't beaten these guys. This Saturday's going to be the one."
Against Freyberg on their home ground, first-five Joey Devine had an 18-point haul from two tries and four conversions.
Vice captain Jack O'Leary added two more tries to his growing tally, while prop Emanual Savage, who won the 2018 title with Metro, also dotted down.
Cosford singled out flanker Neo Tichbon and centre Paiki Ponga, who switched in from fullback, for having standout games.
The coach will be looking for a big effort from his pack this week, having spoken in the past of all the Manawatu teams' propensity to stick to repeat phases through the channels off the breakdown.
"If we just manage to be more aggressive on defence, around the ruck, we'll get turnover ball.
"We feel we've got them out wide, so if the forwards create pressure, the backs will do the rest."
After a couple of players have been unavailable at different stages for the past two weeks, the coach has a full roster to pick from on Saturday.
Kickoff is 1pm at Spriggens Park.
