As expected, the tightest game of the round was between the well-matched teams of Dave Hoskin Carriers Marist and a slightly understrength Marton, with the visitors hanging on for an 18-14 win at Marton Park.
Marist led 15-0 at the break through tries by Vikki Tofa and Ryan Gill, but could manage only another Scott Dowman penalty as Marton scored twice in the second half to close the gap to four points late in the match.
In Tasman Tanning Senior rugby, defending champions Hunterville picked up a 15-3 win over Tech on Spriggens Park, defending the Stihl Shop Wanganui Challenge Shield.
Under new coach and former NZ Heartland player Steelie Koro, Tech stood toe-to-toe with the champions through the early stages to be tied 3-3, before two tries lifted the visitors.
Celtic and Border earned the only bonus points of the round with the biggest wins, beating Marton 31-0 and Utiku Old Boys 44-25 respectively.
