Wairarapa-Bush had the wintry weather at their backs in the first spell and led 9-3 at the interval, an advantage which always looked too slender because of the strength of the wind. And so it proved with Thames Valley pinning them deep in their own territory for most of the second half and keeping the scoreboard ticking over as well.
For coach Rutene the most frustrating aspect of the Wairarapa-Bush effort was their inability to move the ball through more than two or three phases before losing possession through poor handling or inadequate protection of the ball carrier.
"We just couldn't get any go-forward, we'd just start getting some momentum up and we'd turn the ball over. Sure, their defence was pretty good but we made it easy for them, we just kept doing the simple things badly."
Front rowers Richard Puddy, Finnbarr Kerr-Newell and Jonathan Fuimaono and loosies Johnie McFadzean and Ben Periera were the pick of a Wairarapa-Bush pack which lacked the fire seen from them in most of their previous games while none of the backs could be said to have enhanced their reputations, apart from Walters in the goal-kicking department.
Usual skipper Johan Van Vliet was missing from Saturday's game because of a sprained ankle suffered in the previous match against East Coast but he will be available for selection for the semi, as will another player who has been battling injury hassles, midfield back Titapu Pairama-Lewington.
Beating North Otago in Oamaru is never easy but Wairarapa-Bush do have the confidence of knowing they have already achieved that distinction this season, having won a hard-fought preliminary round match there 20-18.
Coach Rutene is "absolutely sure" they will be able to put the frustrations of the Paeroa result behind them and produce a top-notch performance in a game which could earn them home advantage for the Meads Cup grand final, something which would occur if they beat North Otago and West Coast upset Mid-Canterbury.
