Border's try came from halfback Lindsay Horrocks scoring for the second game in a row, but Kaierau would extend their advantage to 19-5 with their second try to second-five Dillon Adrole and another crucial Scott penalty.
The visitors gave themselves an outside shot of at least leaving the Country Club with the shield by virtue of a draw, as reserve prop Kamipeli Latu scored a converted try inside the last ten minutes, but ultimately they would run out of time.
This means Kaierau will take the shield up the Waitotara Valley this coming Saturday to face another team who have never held it in Settler's Honey Ngamatapouri, who find themselves in the likewise new position of table leaders, following a 33-17 win over McCarthy's Transport Ruapehu in Ohakune.
Trying to manufacture a new-look backline after several key player departures, Ruapehu's Premiers had never lost to Ngamatapouri before, but knew it would be daunting to contain the visitor's contingent of Fijian flyers out wide.
New recruit Emitai Logadraudrau scored for the second week in a row, getting a double, while Samu Kubunavanua also dotted down in consecutive games.
Wanting to keep Rochfort Park a fortress, Ruapehu stayed with Ngamatapouri for as long as they could, as after trailing 21-12 at halftime they closed the gap to 21-17 with their third try.
Andre McDonnell and Steelform Wanganui incumbents Gabriel Hakaraia and Jamie Hughes dotted down for the home side.
However, Ngamatapouri broke out to get two more tries and move ahead of likewise unbeaten Taihape at the top of the standings by virtue of their bonus point.
Another piece of silverware swapped clubrooms in the Senior competition, as the new-look Harvey Round Motors Ratana cleaned up Utiku Old Boys 48-17 at the Pa.
Taking the Stihl Shield Wanganui Challenge Shield off Utiku in their first defence, a Ratana team which has seen a couple of former Wanganui players return from neighbouring unions never looked back after leading 34-0 at halftime.
Previous shield holders Bennett's Taihape travelled down the road to face 2019's Division 3 champions Kelso Huntervile, having their first match of the campaign, and the side's fought out a 13-13 draw after a scoreless first half.
It was somewhat unprecedented to have two identical draws in one round, as Counties came from 10-0 down at halftime to tie with Marist Buffalo's 13-13, in the first rugby game played on Cooks Gardens this season.
Marist Celtic sit on top of the table after they smashed Pirates 51-0 in the Spriggens Park derby, while Gemini Pepper Construction Kaierau occupy the all-important second spot, as only two teams will qualify for a final this season, after pulling away from Border 25-13 at the Country Club.
