Opener Chris Stewart made a welcome return from a run of injuries, but needs more time than is available to regain full form, while bowler Angus Dinwiddie has been a champion of lost causes - getting late runs in the tail.
Big hitting Nick Harding will no doubt be looking to finally get going at the top of the order against a visiting side without a victory this campaign.
United CC's top performer has unquestionably been Gurdev Singh, who across all formats has taken eight wickets, second only to Regan Fricker (11), and heads the batting standings with 182 runs at 36.40.
Jaco Vorster, Robbie Speers and Kishan Dhiman can likewise deliver on their day with bat or ball.
Weraroa's only victory this campaign has been against United CC, but Wanganui United will still need full focus if they hope to stand in the winner's circle down in Levin.
On the road for both of their remaining games, United require batting effort support around their 47-year-old former Black Cap Andrew Penn, who if you include the representative Chapple Cup has scored a half century in each of the last three weekends.
Wicketkeeper Chris Sharrock has also had a decent run with the bat, while veteran spinner Robbie Power has taken 26 wickets this summer, although 16 of them were in the Rep Weekend Pro40 rather than Coastal Challenge games.
For the "White Herons" of Weraroa, few have gotten going with the bat – Locky Spring leads those standings with 129 runs in seven games and a squad highest score of 43.
Leg spinner Keegan Maclachlan leads their bowling standings with nine dismissals at a very economical rate, while Caleb O'Connell (eight wickets) has a five-for this summer.
The other big game of the round will be the Horowhenua-Kapiti derby between undefeated sides Levin Old Boys and Paraparaumu at Donnelly Park – the winner looking to cement top of the table to get home advantage for the semifinals and final should they progress that far.
All games start at 12pm.
