Facing the side from down State Highway 1, Hunterville were deadlocked with Marton 7-7 at halftime on a warm March afternoon for playing rugby, but pulled away with 26 points in the second stanza.
The Stihl Shop Wanganui Challenge Shield changed hands in the first game of the season, as Bennett's Taihape got a big boost in confidence by travelling over to McNab Domain and holding off Counties 25-21.
Taihape got revenge for losing their last game of 2018 to Counties 43-24 in their previous shield challenge.
It proved a good weekend for the Marist club, as last year's runnersup Celtic picked up the bonus point in their 29-15 away win to Utiku Old Boys, while 2018's Consolation title winners the Buffalos defeated Black Bull Liquor Pirates 25-11 in the Spriggens Park derby game, after they trailed at halftime.
Pirates stepped into the game at short notice, as they were scheduled for the bye until the Ruapehu seniors pulled out for the season.
