In the 25th minute, first five-eighths Tyrone Albert drew two defenders to put newly arrived Whanganui second five Timoci “Jim” Serwalu over untouched for 14-5.
Kaierau struck back when Heartland back Peceli Malanicagi sliced through to put returning second five Ethan Robinson under the posts for a converted try.
But just before halftime, Border went back-to-back through No 8 and Whanganui representative Josefa Namosimalua scoring a double.
The vistors then cemented their advantage five minutes after the resumption of play. Horrocks cross-kicked for speedster fullback Harry Symes, who dashed under the posts, Albert slotting his fifth conversion.
The comfortable bonus-point win put Border top of the table from Byfords Readimix Taihape, who won the quintessential “game of two halves” against Dave Hosking Carriers Marist 24-17 at Memorial Park.
Taihape scored all their points in the first half, including a double to former Whanganui halfback Kahl Elers-Green, one of the players to shift allegiances down from McCarthy’s Transport Ruapehu after the club again left Premier to focus on Senior.
Former representative fullback Tyler Rodgers-Holden dotted down, while 2023 Heartland Hurricanes Under-20s first five Chad Whale, the latest of his family dynasty, booted nine points.
But the new-look Marist line-up came roaring back in the second half, thanks to tries off the bench from veteran prop Cameron Neilson and Whanganui back Josaia Bogileka, both converted by centre Daniel Kauika to add to his first half penalty.
In Senior rugby, the returning Ruapehu wasted no time getting back in the swing of things, as they dealt the new-look two-time defending champions Ali Arc Logistis Marist Celtic a blow, coming from behind at halftime to win 17-5 at Rochfort Park and lift the Stihl Shop Wanganui Challenge Shield.
On a weekend without many high scores and with games under inclement weather conditions, two sides to really impress were Kelso Hunterville and Forest 360 Marist Knights, who secured big road wins over Black Bull Liquor Pirates (43-7) and Bennett’s Taihape (45-10) respectively.
